Audiology CPT and HCPCS Code Changes for 2026

The following updates to Current Procedural Terminology (CPT ® American Medical Association) related to audiology services are effective January 1, 2026. There are no changes to Healthcare Common Procedures Coding System (HCPCS) Level II codes related to audiology services in 2026. Audiologists can contact ASHA's health care policy team at reimbursement@asha.org for questions.

Note: Audiologists should always check with payers regarding coverage of new or revised billing codes. Coding changes may not always alter payer coverage decisions for specific conditions or services.

See ASHA's annual coding updates for past updates to audiology codes.

Overview of Changes

Starting on January 1, 2026, a new set of 12 Current Procedural Terminology (CPT®) codes will be available to describe the professional services provided by audiologists for hearing device-related services. These new codes will replace the longstanding CPT code set for hearing aid services (92590–92595).

The New Codes Describe the Following Service Categories

1. Candidacy Evaluation (92628-92629)
2. Hearing Aid Selection (92631-92632)
3. Fitting and Follow-Up (92634-92637)
4. Verification (92638- 92641)
5. Assistive Device Services (92642)

Important Reminders

• These new codes primarily describe the audiological services related to air conduction hearing devices. Codes describing services related to implantable devices such as auditory osseointegrated devices and cochlear implants remain as they were previously described elsewhere in the CPT code set.
• These changes apply to CPT codes only and do not affect the V codes for hearing aids and other hearing devices used under the Healthcare Common Procedure Coding System (HCPCS) Level II code set.
• Hearing aids and related services are statutorily excluded from Medicare coverage and are not reimbursable through traditional Medicare Part B. However, Medicare Advantage (Part C) plans may elect to use these codes if they have a hearing aid benefit.
• It is important to check directly with payers, including state Medicaid programs and third-party payers, before using the new codes. Some payers may not immediately replace the deleted codes (CPT codes 92590–92595) or may elect to continue using existing HCPCS codes for hearing aid services.
• These codes currently have no assigned Relative Value Units (RVUs) and are subject to carrier pricing, which mirrors the legacy codes, which were also not statutorily covered under Medicare. Payment will therefore depend on individual payer policy and provider contracts.

New Codes

The following 12 new CPT codes are effective January 1, 2026, to report the professional services audiologists provide for hearing aids and other hearing devices. The new code set replaces the six longstanding codes 92590–92595 (listed below).

Evaluation Services and Hearing Device Selection (Codes 92628–92632)

These codes include candidacy determination and hearing device selection. They recognize varying practice patterns and allow for flexibility in code selection.

Coding Notes:

• CPT codes 92628-92632 are time-based. Timed code requirements follow the “half plus one” rule, meaning that for a 30-minute code, at least 16 minutes must be completed, and a 15- minute code must meet at least 8 minutes to report a unit. Each time-based code has a minimum duration threshold that must be met before it can be billed. Add-on codes apply once the full-time requirement for the base code has been exceeded. For example, a clinician must provide the entire 30-minutes for 92628 before they can bill the add-on code 92629. See New Hearing Device Services Codes: Modernizing Audiologic Services for an outline of the minimum duration threshold for each code.
• 92628-92632 are unilateral or bilateral. Billing is not based on laterality but on time spent providing the service.
• Do not use modifier -52 with timed codes. This modifier can't be used to bypass minimum time requirements or to indicate laterality on timed codes.
  • Some payers may require you to indicate laterality by appending modifiers LT (left side) and/or RT (right side).
• Candidacy (92628, 92629) and selection (92631, 92632) codes cannot be billed on the same date of service, as overlapping preparatory and counseling components exist. If the patient elects amplification during the same encounter, the selection code should be reported, accounting for total time for both evaluation and selection.

Fitting and Follow-Up Services (Codes 92634–92637)

These codes include the work of fitting hearing devices and follow-up services provided after the fitting.

Coding Notes

• CPT codes 92634-92637 are time-based. Timed code requirements follow the “half plus one” rule, meaning that for a 30-minute code, at least 16 minutes must be completed, and a 15- minute code must meet at least 8 minutes to report a unit. Each time-based code has a minimum duration threshold that must be met before it can be billed. Add-on codes apply once the full-time requirement for the base code has been exceeded. For example, a clinician must provide the entire 30-minutes for 92634 before they can bill the add-on code 92635. See New Hearing Device Services Codes: Modernizing Audiologic Services for an outline of the minimum duration threshold for each code.
• 92634-92637 are unilateral or bilateral. Billing is not based on laterality but on time spent providing the service.
  • Some payers may require you to indicate laterality by appending modifiers LT (left side) and/or RT (right side).
• Do not use modifier 52 with timed codes. This modifier can't be used to bypass minimum time requirements or to indicate laterality in timed codes. 
• For simple routine services, such as cleanings or adjustments without orientation, the post-fitting follow-up codes (92636, 92637) may also apply only if the minimum times are met. These encounters document continued patient management rather than diagnostic testing.

Verification & Assistive Device Services (Codes 92638–92642)

These four codes describe additional assessments that require specialized equipment. The verification codes (92638-92641) were created to capture the specific types of verification that may be completed as part of the fitting and follow-up process (92634-92637). 92642 describes services for hearing assistive supplemental technology.

Coding Notes

• CPT codes 92638 and 92639 are untimed add-on codes to be reported in conjunction with fitting or follow-up codes. They cannot be reported separately.
  • 92638 and 92639 may only be billed once the minimum requirements of the applicable base code have been met. Time for the verification codes do not count towards the time for the base code.
  • 92638 is unilateral or bilateral. 
  • 92639 is bilateral. Use modifier 52 for unilateral testing.
• CPT codes 92641 and 92642 are untimed standalone codes that may be reported separately.
  • 92641 can be billed alone or alongside services for other types of (e.g. FM/DM technology, AODs)
  • 92641 is bilateral. Use modifier 52 for unilateral testing.
• Some payers may require you to indicate laterality by appending modifiers LT (left side) and/or RT (right side).
