What 31830 covers

This service involves surgically revising scar tissue of the trachea, which may develop after prior airway surgery, tracheostomy, or injury. An otolaryngologist, head and neck surgeon, or thoracic surgeon typically performs it in an operating room when the tracheal scar itself is the target of the procedure. A scar limited to the skin or the configuration of the tracheostoma is a different operative target.

Report the code when the operative record supports revision of tracheal scar tissue, rather than repair of an acute tracheal injury or closure of a tracheostomy tract or fistula. Document the scar’s location and the work performed. This major surgery has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

How to choose

31800Tracheal repair
This code concerns revision of tracheal scar tissue. Code 31800 is for repair of a tracheal injury, not revision of an established scar.
31805Tracheal repair
Use 31830 for tracheal scar revision; 31805 describes repair of a tracheal injury.
31613Stoma revision
Code 31613 is for simple revision of the tracheostoma. Choose 31830 when the operative target is scar tissue affecting the trachea itself.
31825Tracheal defect repair
Code 31825 is for closing a tracheostomy or fistula with plastic repair. It is not the choice when the procedure revises tracheal scar tissue instead.

31830 billing questions

How is tracheal scar revision different from tracheostoma revision?

Use this code when the operative target is scar tissue affecting the trachea. Codes 31613 and 31614 concern revision of the tracheostoma itself, with the choice depending on the stoma procedure performed.

When would a tracheostomy closure code be more appropriate?

Codes 31820 and 31825 describe closure of a tracheostomy or fistula, with 31825 involving plastic repair. Choose based on whether the documented objective is closure of the tract or revision of tracheal scar tissue.

Can modifier 50 be reported?

No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.

What postoperative care is included?

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

How are other procedures in the same session paid?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50% when performed in the same session.

What documentation supports assistant-at-surgery payment?

The record must document the medical necessity of the assistant. Co-surgeons and team surgery are not permitted for this code.
