Hi there, I'm Dr. Smith, an otolaryngologist with over 10 years of experience in diagnosing and treating disorders of the ear, nose, and throat. Laryngoscopy is a common procedure we perform, and understanding the right CPT codes for billing is crucial. Let me break down the complexities of CPT coding for laryngoscopy for you.

The CPT code for a laryngoscopy can vary significantly depending on several factors, including:

* Purpose of the procedure: Diagnostic vs. surgical
* Approach: Direct vs. indirect
* Instrumentation: Flexible vs. rigid
* Additional procedures performed: Biopsy, vocal cord injection, etc.

Let's delve into these details:

1. Direct Laryngoscopy:

* Diagnostic, separate procedure:
* 31505: Laryngoscopy, direct, operative, with biopsy
* 31515: Laryngoscopy, direct, with injection, sclerosing agent; submucosal
* 31526: Laryngoscopy, direct, with injection, therapeutic drug; therapeutic

* Diagnostic, with other procedures: Often, direct laryngoscopy is part of a more extensive procedure like microlaryngoscopy (for vocal cord lesions) or bronchoscopy. In these cases, the laryngoscopy may not be separately coded, and you'll use the code for the primary procedure.

* Surgical, separate procedure:
* 31530: Laryngoscopy, direct, operative, with excision or destruction of lesion or other structure, simple
* 31535: ... with removal of foreign body
* 31536: ... with dilation
* 31541: ... with excision of lesion(s), with operating microscope or telescope
* 31545: ... with excision of lesion(s), laser surgery
* 31548: ... with arytenoidectomy or epiglottidectomy
* 31575: ... with open excision of lesion of vocal cord, cordectomy, partial or complete; with laryngoplasty
* 31578: ... without laryngoplasty

2. Indirect Laryngoscopy:

Indirect laryngoscopy, typically using a small mirror, is often considered a basic examination technique and might not be separately billable. However, if performed for reasons beyond a routine office visit, consider:

* 92510: Examination of larynx with mirror (indirect laryngoscopy)

Important Coding Notes:

* Modifiers: Always use appropriate modifiers to accurately reflect the service provided. For example, modifier -59 (distinct procedural service) might be necessary if performing a separately identifiable direct laryngoscopy alongside another procedure.
* Age-Specific Codes: Be mindful of specific codes for pediatric patients, like 31501 for direct laryngoscopy with biopsy in children under 12.
* Documentation is Key: Thorough documentation in the patient's medical record, including the type of laryngoscopy, instruments used, findings, and procedures performed, is crucial for accurate coding and potential audits.

For a laryngoscopy, flexible fiberoptic; diagnostic, bill with CPT procedure code 31575. If the CPT definition includes the use of an operating microscope, it is not appropriate to code the microscope code (69990) separately. To report flexible fiberoptic endoscopic procedures, use codes 92612-92617.read more >>
