What 31505 covers

CPT 31505 covers an indirect diagnostic examination of the larynx, typically using a laryngeal mirror to view the vocal folds and surrounding structures. An otolaryngologist commonly performs the exam in an office or clinic when evaluating persistent hoarseness, voice change, throat symptoms, or a suspected laryngeal abnormality. It describes examination only, not biopsy, lesion removal, or another therapeutic procedure.

Report the code when the indirect examination is a distinct service, rather than an integral part of a more extensive laryngeal procedure. Document the indication, examination method, structures viewed, and findings. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is statutorily restricted; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

31505 billing questions

When should 31505 be chosen over 31525?

Use 31505 for an indirect examination, typically with a laryngeal mirror. Use 31525 when the diagnostic examination is performed by direct laryngoscopy.

Can 31505 be reported with a biopsy code?

When a biopsy is performed as part of the laryngoscopy, select the procedure code describing that service, such as 31510 for indirect laryngoscopy with biopsy. Do not separately report 31505 for an examination integral to the biopsy procedure.

How does 31505 differ from flexible laryngoscopy?

31505 describes indirect mirror examination. Use 31575 for diagnostic laryngoscopy performed with a flexible fiberoptic scope.

Does 31505 have a global period?

It has a 0-day global period. Same-day preoperative and postoperative care is included.

Should modifier 50 be appended for both sides?

No. CMS indicates that bilateral adjustment does not apply and modifier 50 is inappropriate for this code.

How are multiple procedures in the same session paid?

CMS pays the highest-valued procedure in full and applies the standard multiple-procedure reduction to the other procedures in that session.

Where these rates come from

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.
