2023 Medicare Physician Fee Schedule

On November 1, 2022 the Centers for Medicare and Medicaid Services (CMS) issued a final rule which revises CY 2023 payment policies under the Medicare Physician Fee Schedule (PFS) and makes other policy changes.

CMS has also published a fact sheet on the 2023 Medicare Physician Fee Schedule Final Rule, available here.

A summary of the major changes is listed below:

Conversion Factor

CMS finalized a CY 2023 Medicare conversion factor (CF) of $33.06, a decrease of $1.55 from the 2022 CF rate of $34.6062. The final CF is largely a result of an expiring 3 percent increase funded to the CF at the end of CY 2022 as required by law. The additional approximate 1.5 percent decrease to the CF is a result of a budget neutrality adjustment primarily from increases to payment for hospital, nursing facility, home health and emergency medicine visits.


During the COVID-19 Public Health Emergency (PHE), CMS significantly expanded the Medicare Telehealth List through the addition of about 150 services that can now be provided via telehealth, including emergency department visits, critical care, home visits, and telephone visits. It also created two new categories of interim telehealth services. Codes in Category 3 of the Medicare Telehealth List are covered on an interim basis until data can be gathered to help determine whether they should become Category 1 or 2 services or be removed from telehealth coverage. Category 3 services will be covered through the end of 2023. Interim services that are not in Category 3 were only slated to be covered until the end of the PHE. In March 2022, the Consolidated Appropriations Act included a provision that extended payment for Medicare telehealth services to all communities in the country, not just rural areas, and allowed patients to continue to receive telehealth services in their homes or wherever they are located without going to a medical facility for an additional 151 days after the end of PHE, which is five months. In an earlier proposal, CMS proposed to similarly extend Medicare telehealth coverage for the codes that were only going to be on the telehealth list through the end of the PHE for an additional five months after the PHE ends. CMS adopted this proposal in its final rule and services included temporarily on the list of telehealth services on an interim basis will now be covered for 151 days after the end of the PHE. CMS also finalized a delay of the in-person visit requirements for mental health services (including substance use disorder) furnished via telehealth until 152 days after the end of the PHE, inline with the Consolidated Appropriations Act of 2022.

Additionally, CMS received requests to add the telephone evaluation and management (E/M) codes to the list of covered telehealth services on a category three basis. CMS noted in the final rule that the agency was declining to add these services on a category 3 basis, noting that while audio-only services will remain appropriate to bill for delivery of mental health services given the change in the telehealth definition made by regulation last year, statute requires that telehealth services be so analogous to in-person care such that the telehealth service is essentially a substitute for a face to-face encounter. In the final rule, CMS again stated that it would not add telephone E/M codes to the list of telehealth services. CMS provided that due to a change in the definition of “telecommunications system” during 2022 rulemaking allowing telehealth services for the diagnosis, evaluation, and treatment of mental health conditions (including substance use disorder) to be furnished through audio-only technology in certain circumstances, the agency did not believe it was appropriate or necessary to add these codes to the list of telehealth services.

CMS also finalized certain changes in coding and payment policies that would take effect five months after the PHE ends. Most importantly, Medicare telehealth services will revert to being paid at the “facility” rate instead of the “non-facility” rate, as CMS believes that the facility payment amount “best reflects the practice expenses, both direct and indirect, involved in furnishing services via telehealth.” CMS finalized this proposal.

Medicare Coverage for Opioid Use Disorder (OUD) Treatment Services Furnished by Opioid Treatment Programs (OTPs)

Methadone Price

CMS is finalizing an earlier proposal that beginning in calendar year (CY) 2023 and for subsequent years, the payment amount for methadone will be based on the payment amount for methadone in CY 2021 as determined under § 410.67(d)(2)(i)(B)(1) and updated by the Produce Price Index (PPI) for Pharmaceuticals for Human Use (Prescription). The 2023 price for the drug component of the OTP bundle for methadone will be $39.29, a roughly $2 increase from the current rate.

OTP Bundle - Therapy

Currently, the individual therapy component of the OTP bundles is priced based on a crosswalk to CPT code 90832 (Psychotherapy, 30 minutes with patient). CMS has received feedback that patients with OUD are often utilizing more individual therapy than the current 30 minute crosswalk suggests. Therefore, CMS finalized a proposal to modify the payment rate for the non-drug component of the bundled payment for an episode of care to base the rate for individual therapy on a crosswalk to CPT code 90834 (Psychotherapy, 45 minutes with patient).

Beginning with CY 2023, CMS would apply the Medicare Economic Index (MEI) from 2021-23 to update the 2023 payment rate for the non-drug components of the bundle.

CMS also clarified that practitioners can bill for OTP bundled services even if the duration of a therapy session is less than 45 minutes, noting that “This crosswalk code is being used for the purposes of valuation, but we do not intend it to be a requirement regarding the number of minutes spent in an individual therapy session in order for the service to qualify as an OUD treatment service.”

G2076 – OTP Intake Activities

CMS finalized a proposal to allow G2076 to be furnished via two-way audio-video communications technology when billed for the initiation of treatment with buprenorphine, to the extent that the use of audio-video telecommunications technology to initiate treatment with buprenorphine is authorized by DEA and SAMHSA at the time the service is furnished. CMS also finalized its proposal to permit the use of audio-only communication technology to initiate treatment with buprenorphine in cases where audio-video technology is not available to the beneficiary. CMS interprets the requirement that audio/video technology is “not available to the beneficiary” to include circumstances in which the beneficiary is not capable of or has not consented to the use of devices that permit a two-way, audio/video interaction.


CMS sought comment on whether to allow periodic assessments (G2077) to continue to be furnished using audio-only communication technology following the end of the PHE for COVID-19 for patients who are receiving treatment via buprenorphine, and if this flexibility should also continue to apply to patients receiving methadone or naltrexone. Prior to the declaration of the PHE, the CY 2021 PFS Final Rule amended the definition of periodic assessment in Section 410.67(b)(7) to say that the definition is limited to a face-to-face encounter, and that a clinician must perform a face-to-face medical exam or biopsychosocial assessment to bill G2077. In 2023, CMS has finalized regulations that will allow G2077 to be furnished using audio-only communication technology following the end of the PHE for COVID-19 for patients who are receiving treatment via buprenorphine. CMS notes in the final rule that it will continue to evaluate whether to extend this flexibility to patients treated with naltrexone and methadone.

Mobile Units

CMS finalized policy clarifying that OTPs can bill Medicare for medically reasonable and necessary services furnished via mobile units in accordance with SAMHSA and DEA guidance. The agency also finalized a proposal allowing locality adjustments for services furnished via mobile units to be applied as if the service were furnished at the physical location of the OTP registered with DEA and certified by SAMHSA.

Requirement for Electronic Prescribing for Controlled Substances (EPCS)

CMS is finalizing a proposal to extend the existing non-compliance action of sending letters to non-compliant prescribers for the EPCS program from 2023 into 2024. These letters would consist of a notification to prescribers that they are violating the EPCS requirement, information about how they can come into compliance, the benefits of EPCS, an information solicitation as to why they are not conducting EPCS, and a link to the CMS portal to request a waiver. CMS will utilize email addresses as the primary method of contacting prescribers.

While CMS noted in it proposed rule that the agency plans to increase the severity of penalties beginning in CY 2025, CMS added in the final rule that it continues to consider potential penalties and therefore does not intend to finalize any additional penalties at this time. Below is a list of potential penalties that CMS included in the earlier proposed rule for non-compliant prescribers beginning in CY 2025:

  • Requiring a non-compliant prescriber to enter into a corrective action plan, which would require the non-compliant prescriber to comply with the EPCS requirement within 2 years prior to applying other potential actions outlined below;
  • Posting a non-compliant prescriber’s name on the CMS website and identifying the prescriber as non-compliant;
  • Public reporting of EPCS compliance status, including that a prescriber is noncompliant, on the Care Compare website;
  • Referral of non-compliant prescribers to the DEA to support potential investigations;
  • Sharing the list of EPCS non-compliant prescribers with the States; and/or
  • Referral for potential fraud, waste and abuse review.

Annual Alcohol Misuse and Depression Screenings

CMS finalized a proposal to revise the code descriptors for G0442 and G0444 from 15 min to 5-15 minutes following feedback that the 15-minute threshold in the code descriptors for G0442 and G0444 is too high and limits providers ability to bill the codes. CMS did not respond to ASAM’s request that the agency reexamine the payment and coverage policy for these services to ensure that qualified practitioners are eligible to bill for these services and to ensure that the policy was consistent with the latest guidance from the US Preventive Services Task Force (USPSTF).

Chronic Pain Management (CPM) Services

CMS is finalized a proposal to create two bundled codes to describe chronic pain management and treatment. The agency is finalizing its proposal to define chronic pain as “persistent or recurrent pain lasting longer than three months.” The code descriptors will read as follows:

  • G3002: Chronic pain management and treatment, monthly bundle including, diagnosis; assessment and monitoring; administration of a validated pain rating scale or tool; the development, implementation, revision, and/or maintenance of a person-centered care plan that includes strengths, goals, clinical needs, and desired outcomes; overall treatment management; facilitation and coordination of any necessary behavioral health treatment; medication management; pain and health literacy counseling; any necessary chronic pain-related crisis care; and ongoing communication and care coordination between relevant practitioners furnishing care, e.g. physical therapy and occupational therapy, complementary and integrative approaches, and community-based care, as appropriate. Required initial face-to-face visit at least 30 minutes provided by a physician or other qualified health professional; first 30 minutes personally provided by physician or other qualified health care professional, per calendar month. (When using G3002, 30 minutes must be met or exceeded.)
  • G3003: (Each additional 15 minutes of chronic pain management and treatment by a physician or other qualified health care professional, per calendar month. (List separately in addition to code for G3002. When using G3003, 15 minutes must be met or exceeded.)

    After seeking comment from interested parties, CMS also finalizing other provisions related to this bundle, including that:

  • These codes will not be used to report acute pain;
  • The practitioner must see the patient in-person the first time G3002 is billed;
  • A physician or other qualified health practitioner may bill HCPCS code G3003, for each additional 15 minutes of care, an unlimited number of times, as medically necessary, per month, after HCPCS code G3002 has been billed;
  • CMS is not limiting the types of physician specialties, or the types of qualified health professionals, who can furnish CPM services, as long as they can furnish all of the service elements of HCPCS code G3002, including prescribing medication as needed, within their scope of practice in the State in which the services are furnished;
  • These codes will not be limited to specific places of service, other than that G3003 must be provided in person for the first visit; and
  • Any of the CPM in-person components included in HCPCS codes G3002 and G3003 may be furnished via telehealth, as clinically appropriate.

Rural Health Clinics (RHCs) and Federally Qualified Health Centers (FQHCs)

CMS finalized its proposal to add the CPM and behavioral health integration services to the all inclusive RHC/FQHC payment for general care management (G0511).

CMS also finalized its proposals to implement the telehealth provisions in the Consolidated Appropriations Act, 2022 (CAA, 2022) via program instruction or other sub-regulatory guidance to ensure a smooth transition after the end of the PHE. These policies extend certain flexibilities in place during the PHE for 151 days after the PHE ends, including allowing payment for RHCs and FQHCs for furnishing telehealth services (other than mental health visits that can be furnished virtually on a permanent basis) under the payment methodology established for the PHE. The CAA, 2022 also delays the in-person visit requirements for mental health visits furnished by RHCs and FQHCs via telecommunications technology until 152 days after the end of the PHE.

Supervision Requirements for Behavioral Health Services

CMS finalized its proposal to amend the direct supervision requirement under the agency’s “incident to” regulation at § 410.26 to allow behavioral health services to be furnished under the general supervision of a physician or non-physician practitioner (NPP) when these services or supplies are provided by auxiliary personnel incident to the services of a physician or NPP.

Comment Solicitation on Intensive Outpatient Mental Health Treatment, including Substance Use Disorder (SUD) Treatment, Furnished by Intensive Outpatient Programs (IOPs)

As part of the agency’s Behavioral Health Strategy, CMS sought comments on whether or not the current coding and payment mechanisms under the PFS adequately account for intensive outpatient services that are part of a continuum of care in the treatment of substance use disorder. CMS thanked commenters for their responses and indicated that the agency will consider the comments for future rulemaking.

On November 2nd, 2021, the Centers for Medicare and Medicaid Services (CMS) issued a Final Rule which revises CY 2022 payment policies under the Medicare Physician Fee Schedule (PFS) and makes other policy changes, including the implementation of certain provisions of the Substance Use-Disorder Prevention that Promotes Opioid Recovery and Treatment (SUPPORT) for Patients and Communities Act (the SUPPORT Act). 

CMS has also published a fact sheet on the 2022 Medicare Physician Fee Schedule Final Rule, available here.

The 3.75% payment increase provided by the Consolidated Appropriations Act of 2021 is set to expire at the end of 2021, absent Congressional action. This along with a decrease in the Medicare conversion factor will mean that several specialties, including Addiction Medicine (ADM), will receive less Medicare dollars as a result during the 2022 payment year.

CMS also finalized changes to other programs. The primary changes are as follows:

Opioid Treatment Programs

CMS finalized rules enabling Opioid Treatment Professionals (OTPs) to furnish counseling and therapy services via audio-only (telephone calls) technologies in cases where two-way audio and video communication is unavailable to the beneficiary, after the conclusion of the public health emergency (PHE) for COVID-19.This includes circumstances where the beneficiary is not capable or denies consent to the use of two-way audio and video interaction.

Electronic Prescribing of Controlled Substances (EPCS)

CMS finalized plans to implement the second phase of the electronic prescribing requirement included in the SUPPORT Act. This revision codifies certain exemptions to the requirement, including when:

  • The prescriber and dispensing pharmacy are the same entity;
  • The prescriber issues 100 or fewer controlled substance prescriptions for Part D drugs per calendar year;
  • The prescriber is located in the same geographic area as a natural disaster or;
  • Prescribers are approved for a waiver for extraordinary circumstances (e.g., a sudden influx of patients due to a pandemic). Other extraordinary circumstance exemptions that CMS recently added include technological failures and cybersecurity attacks.   

    CMS finalized rules enabling prescribers to request a waiver where circumstances beyond their control prevent them from electronically prescribing a controlled substance covered by Part D.

    Formal compliance actions will begin on January 1st, 2023. In the interim, CMS will enforce compliance through compliance letters.


CMS announced that it will allow certain services added to the Medicare telehealth list to remain on the list until the end of 2023. The complete list of Medicare telehealth services can be found here. Additionally, CMS finalized proposals to:

  • Continue reimbursement for mental health telehealth services without geographic restrictions, provided that the patient has an existing in-person relationship with the provider. CMS requires that an in-person relationship include 1 in-person visit within a 6 month period prior to the telehealth encounter, and at least 1 in-person visit every 6 months thereafter.
  • Continue reimbursement for mental health telehealth services in the home, provided that providers and patients complete 1 in-person visit within 6 months of the initial telehealth service, and at least once for every 12 months afterward with exceptions for situations where providers and patients agree that the risk/burden of in-person meetings outweighs the benefit. Requirement for in-person meetings can be satisfied by other physicians within the same specialty and subspecialty group if the existing provider is unavailable.  
  • Amend current regulatory requirement for interactive telecommunications (multimedia communications equipment that includes, at a minimum, audio and video equipment permitting two-way, real-time interactive communication between the patient and distant site physician or practitioner) to include audio-only communication technology when used for telehealth services for the diagnosis, evaluation, or treatment of mental health disorders furnished to established patients in their homes.
  • Limit the use of an audio-only interactive telecommunications system to mental health services furnished by practitioners who have the capability to furnish two-way, audio/video communications, but where the beneficiary is not capable of using, or does not consent to, the use of two-way, audio/video technology.
    • CMS clarified that substance use disorder (SUD) is included in the revised definition above such that practitioners can use audio-only communication technology to provide treatment for a SUD. CMS also clarified that the in-person requirements described above do not apply to treatment of a patient diagnosed with a SUD for treatment of that disorder or a co-occurring mental health disorder.
  • Require the use of a new modifier for services furnished using audio-only communications, which would serve to certify that the practitioner had the capability to provide two-way, audio/video technology, but instead, used audio-only technology due to beneficiary choice or limitations.

Other Provisions

CMS confirmed that it will extend its audio-only flexibility for OTPs to the therapy and counseling portions of the bundled payments for SUDs in office-based practices.

CMS finalized coding and payment for a take-home supply of 8 mg naloxone hydrochloride nasal spray.



On December 2, 2020, the Centers for Medicare and Medicaid Services (CMS) released the Final Rule  that makes revisions to the CY 2021 payment policies under the Medicare Physician Fee Schedule (PFS) and makes other policy changes, including implementation of certain provisions of the Substance Use-Disorder Prevention that Promotes Opioid Recovery and Treatment (SUPPORT) for Patients and Communities Act (the SUPPORT Act). 

CMS has also published a fact sheet on the PFS final rule, available here 

The Consolidated Appropriations Act, 2021, signed into law on December 22, 2020, made several
modifications to the CY2021 PFS:

• Provided a 3.75% increase in MPFS payments for CY 2021.
• Suspended the 2% payment adjustment (sequestration) through March 31, 2021.
• Reinstated the 1.0 floor on the work Geographic Practice Cost Index through CY 2023.
• Delayed implementation of the inherent complexity add-on code for evaluation and
management services (G2211) until CY 2024.


The main changes are as follows:

  • CMS adopted AMA CPT coding and documentation guidelines to report office and outpatient E/M visits based on either medical decision-making or physician time and reduce unnecessary documentation. These changes will be effective beginning January 1, 2021.  Learn more about the changes here.
  • CMS permanently added several services to the Medicare telehealth services list, including Group Psychotherapy.

  • Medicare Coverage for Opioid Use Disorder Treatment Services Furnished by Opioid Treatment Programs (OTP).

CMS finalized its proposal to extend the definition of OUD treatment services to include opioid antagonist medications, specifically naloxone, that are approved by Food and Drug Administration under section 505 of the Federal Food, Drug, and Cosmetic Act for emergency treatment of opioid overdose, and overdose education provided in conjunction with opioid antagonist medication. Read more in the CMS Factsheet.

  • Bundled Payments under the PFS for Substance Use Disorders (HCPCS codes G2086, G2087, and G2088)

In the CY 2020 PFS final rule (84 FR 62673), CMS finalized the creation of new coding and payment describing a bundled episode of care for the treatment of Opioid Use Disorder (OUD). In response to requests to expand those bundled payments to be inclusive of other SUDs, not just OUD, CMS is revising the code descriptors by replacing “opioid use disorder” with “a substance use disorder.” The payment and billing rules otherwise remain unchanged.

  • Initiation of Medication Assisted Treatment (MAT) in the Emergency Department (HCPCS code G2213)

 In the CY 2020 PFS proposed rule, CMS sought comment on the use of medication assisted treatment (MAT) in the emergency department (ED) setting, including initiation of MAT and the potential for either referral or follow-up care. It was persuaded by the comments received that this work is not currently accounted for in the existing code set. To account for the resource costs involved with initiation of medication for the treatment of opioid use disorder in the ED and referral for follow-up care, CMS is creating one add-on G-code (G2213) to be billed with E/M visit codes used in the ED setting.

  • Electronic Prescribing of Controlled Substances 

Section 2003 of the SUPPORT Act requires that, effective January 1, 2021, the prescribing of a Schedule II, III, IV, or V controlled substance under Medicare Part D be done electronically in accordance with an electronic prescription drug program. CMS finalized the provision with an effective date of January 1, 2021 and a compliance date of January 1, 2022 to encourage prescribers to implement EPCS as soon as possible, while helping ensure that its compliance process is conducted thoughtfully. It noted that physicians who do not implement EPCS “until January 1, 2022 will still be considered compliant with the requirement.

Read the full rule

On November 1, 2019, the Centers for Medicare and Medicaid Services (CMS) released the Final Rule that makes revisions to the CY 2020 payment policies under the Medicare Physician Fee Schedule (PFS) and other policy changes, including those required to implement certain provisions of the Substance Use-Disorder Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities Act (the SUPPORT Act) related to Medicare Part B payment. 

CMS has also published a fact sheet on the PFS Final Rule for 2020.  

Three sections of the Final Rule are particularly relevant to ASAM members and are summarized below: 

In addition, the Final Rule aligns Medicare E/M coding with changes adopted by the American Medical Association (AMA) Current Procedural Terminology (CPT) Editorial Panel for new and existing patient office E/M visits. A summary of those changes can be found here. The AMA built an educational website dedicated solely to the E/M changes, available here, which will be updated during the year. CMS also adopted the AMA Specialty Society Relative Value Scale Update Committee (RUC) recommended values for the office E/M visit codes for CY 2021 and the new add-on CPT code for prolonged service time. The AMA RUC-recommended values are anticipated to increase payment for office E/M visits.

There are now separately reimbursable “Interprofessional Telephone/Internet/Electronic Health Record Consultation” CPT codes that describe assessment and management services furnished when a patient’s treating physician or other qualified health care professional (OQHCP) requests the opinion and/or treatment advice of a physician (or OQHCP, if eligible) with specialty expertise (the consultant) to assist in the diagnosis and/or management of the patient’s problem without the patient’s face-to-face contact with the consultant.  The American Psychiatric Association (APA) has created resources for psychiatrists about these codes. Read more here on the APA's website. (See APA’s first bullet point under “Codes to Know”.)

This letter clarifies Medicaid and CHIP policy for coverage and payment of interprofessional consultations. It clarifies that Medicaid and CHIP coverage and payment of interprofessional consultation is permissible, even when the beneficiary is not present, as long as the consultation is for the direct benefit of the beneficiary. This guidance supersedes CMS’s previous policy that prohibited coverage and payment of interprofessional consultation as a distinct service, because the presence of the patient was required under that earlier policy guidance for specialty consultation services to be directly covered.
