Clinical Context
A typical patient is an adult or pediatric outpatient with documented hearing loss or significant difficulty communicating in noisy environments who is evaluated by an audiologist or otolaryngologist. The patient reports trouble hearing speech in classrooms, workplaces, or at home despite hearing aids or cochlear implants. The clinical workflow begins with a diagnostic audiologic assessment (pure-tone and speech audiometry, aided testing as needed) and discussion of communication goals. When assistive hearing technology is indicated, the provider selects and fits devices such as remote microphones (FM/DM systems, remote mics) or alerting devices (visual or tactile alarms) to improve speech access. The visit includes device selection, verification of fit and function, programming or pairing with the patient’s hearing devices, real‑world listening checks, counseling on use and maintenance, and documentation of device performance and patient instruction. Follow-up is scheduled for device adjustment and objective/subjective outcome review.
Coding Specifications
| Modifier | Description | When to Use |
|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day | Use when a medically necessary E/M visit is provided in addition to the device fitting and is clearly documented as separate. |
26 | Professional component | Use when billing only the professional component of a service separate from a technical component billed by another entity.
59 | Distinct procedural service | Use when the fit of assistive hearing technology is a separate, distinct service from other procedures performed the same day.
RT | Right side | Use when device fitting is laterality-specific and documentation supports right-sided service.
LT | Left side | Use when device fitting is laterality-specific and documentation supports left-sided service.
91 | Repeat clinical diagnostic laboratory test | Rarely applicable; use only if repeat objective testing is billed and meets payor criteria.
TC | Technical component | Use when billing only the technical component of a service performed by an entity separate from the clinician.
GA | Waiver of liability statement on file (Medicare) | Use when a voluntary waiver is on file for services likely non-covered by Medicare and payer rules permit.
GZ | Item or service expected to be denied as not reasonable and necessary | Use when the provider documents expectation of denial and does not have an Advance Beneficiary Notice/waiver.
KX | Requirements specified in the medical policy have been met | Use when coverage requires attestation that medical necessity criteria were satisfied.
