What 30545 covers

This operation corrects choanal atresia, a congenital blockage between the nasal cavity and throat, by reaching the obstructed posterior nasal airway through the palate. An otolaryngologist typically performs it in an operating room when the surgeon selects this approach to open the blocked passage. Choanal atresia can cause serious breathing difficulty in newborns, particularly when both sides are blocked; the diagnosis and operative findings establish the condition being treated.

Report 30545 for the transpalatal repair, not for an intranasal repair. The operative report should identify the atresia, the approach used, and the repair performed. Medicare assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. If 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% multiple-procedure reduction. Bilateral adjustment is not appropriate for this code. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

How to choose

30540Choanal atresia repair
Both codes repair choanal atresia; 30545 is for the transpalatal approach, while 30540 is for the intranasal approach.
30520Septoplasty
Use 30520 for repair of the nasal septum. It does not describe opening congenital choanal obstruction through the palate.
30560Nasal adhesion lysis
30560 treats intranasal synechia, or adhesions, rather than choanal atresia. Select based on the obstruction documented and treated.

30545 billing questions

How do I choose between 30545 and 30540?

Choose 30545 when the surgeon repairs choanal atresia through a transpalatal approach. Code 30540 describes repair through an intranasal approach.

What documentation supports 30545?

Document the choanal atresia, the transpalatal approach, and the operative work performed to correct the blockage. The operative report should make the approach distinguishable from an intranasal repair.

Can I append modifier 50 for bilateral atresia?

No. CMS identifies bilateral adjustment as inappropriate for this code, even when atresia affects both sides.

How does the 90-day global period affect postoperative billing?

The day-before preoperative visit and 90 days of related postoperative care are included in the global period. Care unrelated to the repair is not described by that global-period rule.

Can an assistant or another surgeon be reported?

An assistant at surgery may be paid. CMS does not permit co-surgeons or team surgery for this code.

What happens when another procedure is performed in the same session?

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.

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.
