Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 31571 covers

An otolaryngologist uses direct laryngoscopy to reach the vocal folds and deliver a therapeutic injection under an operating microscope or telescope. For example, a surgeon may inject a vocal fold scar with medication under magnified visualization. The operative note should identify the treated fold or folds, injected agent, therapeutic indication, and use of the microscope or telescope.

Report 31571 when the direct laryngoscopic injection includes this magnified instrumentation; 31570 describes the related injection without it. Distinguish therapeutic injection from injection intended to augment a vocal fold, which is represented by a different approach and code. The CMS global period is 0 days, so same-day preoperative and postoperative care is included. CMS endoscopy-family pricing applies when related endoscopies are performed together. For bilateral treatment, report the service without modifier 50; the descriptor and anatomy make that modifier inappropriate. Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
