What Q4112 covers
Cymetra is a micronized human dermal matrix supplied for injection as a soft-tissue augmenting material. Otolaryngologists may use it for vocal-fold augmentation, including treatment of glottic insufficiency; it may also be used for other soft-tissue augmentation procedures. The clinician reports the material separately from the procedure used to inject it, such as laryngoscopy with vocal-fold injection.
Q4112 represents 1 cc of Cymetra; report the number of units according to the volume used. Medicare assigns carrier-priced status: there is no national physician fee schedule payment, and the Medicare Administrative Contractor sets payment for each claim. The HCPCS pricing method places the code under the physician fee schedule, with coverage left to the contractor’s judgment. Q4112 is a technical-component-only code, with a separate code covering interpretation.
