Audiology CPT Codes for 2026 + Modifiers

Accurate CPT® coding and modifier use are essential for audiologists to ensure proper reimbursement, reduce denials, and stay compliant with payer documentation rules. For 2026, audiology practices should pay special attention to a major update impacting hearing aid and hearing device-related professional services, along with ongoing best practices for vestibular and audiometric testing.

Major Audiology CPT® Updates for 2026

Critical update: Effective January 1, 2026, the legacy hearing aid/hearing device service codes 92590–92595 have been deleted and replaced by a new set of 12 CPT® codes (92628–92642) that more specifically describe hearing device professional services, including time-based reporting for certain components of care.

These changes apply to CPT® professional service reporting and do not replace HCPCS “V” codes used for hearing aid devices when applicable. Payer adoption and coverage policies may vary, so it is important to confirm plan requirements when implementing the new code set.

Hearing Device Professional Service Codes for 2026 (New)

The following codes describe professional services related to hearing device care. Several of these codes are time-based and require documentation that supports the time and work performed (for example: candidacy evaluation, device selection, fitting, follow-up, and verification).

• 92628–92632 – Evaluation services and hearing device selection (time-based options included)
• 92634–92637 – Hearing device fitting and post-fitting follow-up services
• 92638–92639 – Electroacoustic analysis/verification services
• 92641–92642 – Additional verification and/or related device service components

Vestibular Implant Procedures (Category III)

These Category III codes describe emerging vestibular implant technologies and related services. Coverage and payment are payer-dependent.

• 0725T – Surgical implantation or removal of a vestibular implant.
• 0726T – Surgical implantation or removal of a vestibular implant, alternative procedural approach.
• 0727T – Surgical implantation or removal of a vestibular implant using a different technique.
• 0728T – Initial setup, calibration, and configuration of a vestibular implant for diagnostic analysis, unilateral.
• 0729T – Subsequent programming, adjustment, and configuration of a vestibular implant for diagnostic analysis, unilateral.

Vestibular and Balance Testing

Vestibular testing supports evaluation of dizziness, vertigo, imbalance, and suspected vestibular disorders. Many services are comprehensive and can be subject to bundling edits, so the test performed should drive code selection.

• 92517 – Cervical vestibular evoked myogenic potential (cVEMP) testing, with interpretation and report.
• 92518 – Ocular vestibular evoked myogenic potential (oVEMP) testing, with interpretation and report.
• 92519 – Combined cVEMP and oVEMP testing, with interpretation and report.
• 92537 – Bilateral caloric vestibular testing with bithermal irrigations, with recording.
• 92538 – Bilateral caloric vestibular testing with monothermal irrigations, with recording.
• 92540 – Comprehensive vestibular evaluation including multiple nystagmus tests, optokinetic stimulation, and tracking, with recording.
• 92541 – Spontaneous, gaze, and fixation nystagmus testing, with recording.
• 92542 – Positional nystagmus testing in multiple positions, with recording.
• 92544 – Optokinetic nystagmus testing with bidirectional stimulation.
• 92545 – Oscillating tracking test for eye movements.
• 92546 – Sinusoidal vertical axis rotational testing.
• 92547 – Use of vertical electrodes during vestibular testing (reported separately when applicable).
• 92548 – Computerized dynamic posturography evaluating sensory organization, with interpretation and report.
• 92549 – Computerized dynamic posturography including sensory organization, motor control, and adaptation testing.

Audiometric Testing

Audiometric testing codes remain among the most common services billed in audiology. Select codes based on what was actually performed (air vs. air/bone thresholds, speech testing, and whether comprehensive testing applies).

• 92550 – Tympanometry and acoustic reflex threshold testing.
• 92552 – Pure tone audiometry, air conduction only.
• 92553 – Pure tone audiometry, air and bone conduction.
• 92555 – Speech audiometry threshold testing.
• 92556 – Speech audiometry threshold testing with speech recognition.
• 92557 – Comprehensive audiometry threshold evaluation and speech recognition.
• 92561 – Bekesy audiometry.
• 92562 – Loudness balance testing.
• 92563 – Tone decay testing.
• 92564 – Short increment sensitivity index (SISI) testing.

Audiology Billing Modifiers

Modifiers may be needed to indicate repeat testing, laterality, or distinct services performed on the same date. Always follow payer policy and ensure documentation supports modifier use.

Audiology Billing Tips for 2026

• Update hearing device workflows. Remove deleted codes 92590–92595 from templates and adopt the new 92628–92642 code family where applicable.
• Support time-based reporting. For time-based hearing device services, include total time and clearly document what was performed.
• Document medical necessity. Vestibular and balance testing should be supported by symptoms such as dizziness, vertigo, imbalance, or suspected vestibular dysfunction.
• Avoid unbundling and overlap. Many vestibular services are comprehensive; choose codes that match the test performed and avoid reporting overlapping caloric methods together.
• Use modifiers carefully. Apply -59 or laterality modifiers only when documentation clearly supports distinct testing or payer requirements.

Final Thoughts

2026 brings a meaningful shift in how hearing device professional services are reported, while diagnostic audiology and vestibular testing codes remain core to day-to-day billing. Keeping your audiology CPT codes and modifiers for 2026 current—and aligning documentation with payer expectations—helps protect reimbursement, reduce denials, and maintain compliance.
