What 31820 covers

This service closes a persistent opening between the trachea and skin, commonly a tracheocutaneous fistula that remains after a tracheostomy tube has been removed. An otolaryngologist or thoracic surgeon typically performs the operation in a surgical setting, closing the tract without plastic reconstruction. The code is for closure of the established opening, rather than repair of an acute tracheal injury or revision of a tracheostomy scar alone.

Select this code when the operative report supports closure without plastic repair. Documentation should identify the opening being treated and describe the closure performed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed 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 for this service. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

31820 billing questions

How does this differ from 31825?

31820 is for closure without plastic repair. Use 31825 when the closure includes plastic repair.

Is this the code for an acute tracheal injury?

No. This code describes closure of a tracheostomy opening or fistula. Codes 31800 and 31805 describe tracheal repair for injury, depending on the site.

Can modifier 50 be used for openings on both sides?

No. The code's descriptor and anatomy make bilateral adjustment inappropriate; do not append modifier 50.

The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.

When may an assistant-at-surgery be paid?

Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted for this code.

How does another procedure in the same session affect payment?

The highest-valued procedure is paid in full, and other procedures performed in that session are subject to the standard multiple procedure reduction.

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.
