National Coverage Determination (NCD) for Tinnitus Masking -
Tinnitus Masking is not considered reasonable and necessary for the diagnosis or treatment of an injury or disease.
Tinnitus Masking (CPT code 92599 (unspecified otolaryngologic procedure)) is noted as a noncovered service.
Some of the emerging techniques and associated tools are considered investigational and this LCD does NOT endorse such procedure.
• NOTE: An Advance Beneficiary Notice (ABN) is required for items and services not covered by Medicare
due to being considered not medically reasonable and necessary.
◦ The beneficiary should be thoroughly educated about the benefits and risks of this item or service.
◦ If such notice is not given, providers may not shift financial liability for such items or services to beneficiaries
should a claim for such items or services be denied by Medicare.
• Tinnitus masking is considered an experimental therapy at this time because of the lack of controlled clinical trials
demonstrating effectiveness and the unstudied possibility of serious toxicity in the form of noise induced hearing
• Therefore, it is not covered.

• The masker produces external sounds to distract the person from the tinnitus.
• By producing an external sound a few decibels above the person's audible threshold, tinnitus masking is thought to
provide sufficient distraction from subjective idiopathic tinnitus to alleviate the discomfort and debilitation
associated with endogenous sounds within the ear and/or head area.
