COVID-19: CMS Allowing Audio-Only Calls for OTP Therapy, Counseling, and Periodic Assessments

CMS revised regulation text to allow audio-only telephone calls for the therapy and counseling portions of the weekly bundles and the add-on code for additional counseling or therapy (HCPCS code G2080) for beneficiaries with opioid use disorders, provided all other requirements are met. Providers may conduct the periodic patient assessments (HCPCS code G2077) via two-way interactive audio-video communication technology or by telephone only in cases where the beneficiary does not have access to two-way interactive technology.

This change, effective March 1, 2020, is necessary so beneficiaries without access to interactive audio-video communication technology can continue receiving these important services.

This will apply for the duration of the public health emergency for the COVID-19 pandemic.  OTPs should continue to use Place of Service code 58 on claims for all OTP services, including those furnished using audio-video or audio-only communication technology.


As of January 1, 2020, Medicare pays enrolled Opioid Treatment Programs (OTPs) bundled payments based on weekly episodes of care for services including:

  • FDA-approved treatment medications for the treatment of OUD
  • The dispensing and administration of such medications (if applicable)
  • Substance use counseling
  • Individual and group therapy
  • Toxicology testing

Medicare will also adjust payments for the bundled payment amount for intake activities and periodic assessments, which are required by SAMHSA, as well as for additional counseling and therapy, and take-home supplies of medications.

There is NO copayment for OTP services for people with Medicare.

Review the OTP Medicare Billing & Payment Booklet (PDF) to learn about:

  • Covered opioid use disorder (OUD) Treatment Services
  • Coding and submitting claims for OTP services
  • Payment and remittance advice (RA)

If you’re a clinician, visit the office-based OUD treatment services webpage for more information on billing.  Clinicians can’t use OTP codes to bill for office-based treatment.

The CY 2023 National Final Unadjusted Payment Rates for OTPs  describe OTP HCPCS G-codes, bundled payments, and the total unadjusted payment assigned to each rate code. 

CMS adjusts the non-drug component of the OTP bundled payments for geographic locality so payment rates will vary depending on the OTP’s location.  CMS also geographically adjusts the add-on payments for non-drug services (i.e., intake activities, periodic assessments, additional counseling and therapy).

The CY 2023 Physician Fee Schedule final rule includes information for Medicare-enrolled OTPs:

  • Revises pricing methodology for drug component of methadone weekly bundle and add-on code for take-home methadone supplies
  • Modifies payment rate for individual therapy in non-drug component of the bundled payments for episodes of care
  • Allows OTP intake add-on code to initiate treatment with buprenorphine provided via 2-way audio-video communications technology or audio-only technology when audio-video technology isn’t available and all requirements are met
  • Extends the flexibility through the end of CY 2023 to provide periodic assessments via audio-only when video isn’t available, when authorized by SAMHSA and DEA
  • Clarifies OTPs can bill for medically reasonable and necessary services provided via mobile units

After the conclusion of the PHE, CMS expects OTPs to add the following modifiers on claims for HCPCS code G2076, G2077, and  G2080:

  • Modifier 95: for counseling and therapy provided using audio-video telecommunications
  • Modifier 93: for counseling and therapy provided using audio-only telecommunications
