Foot & Ankle Orthopedics in the ASC: CPT Codes and Coverage

Foot and ankle orthopedic surgeons treat conditions of the forefoot, midfoot, and hindfoot, billed in the foot and ankle CPT range 28000-28899. These span minor soft-tissue work like 28001 (drainage of a bursa of the foot) to bunion corrections like 28296 (distal first metatarsal osteotomy for hallux valgus). Whether Medicare pays a code in an ASC depends on the CMS addenda: codes on Addendum AA are on the ASC Covered Procedures List, while Addendum EE codes are excluded from ASC payment.

DataLily's procedure library tracks CPT-specific prior-authorization and documentation requirements so billing and coding teams can confirm what each payer expects before the case is scheduled.

Are foot and ankle surgeries performed in an ASC?

Many are. A large share of forefoot and soft-tissue foot and ankle procedures are performed in ambulatory surgery centers and billed with place-of-service 24. Whether Medicare pays a specific code in an ASC depends on its CMS addendum status: codes on Addendum AA are on the ASC Covered Procedures List, while Addendum EE codes are excluded from ASC payment. Check each code's status before scheduling.

What CPT codes does foot and ankle orthopedics use?

Foot and ankle procedures fall in the CPT range 28000-28899, which spans soft-tissue, bone, and joint work on the forefoot, midfoot, and hindfoot. Examples include 28285 (repair of hammertoe), 28296 and 28297 (hallux valgus corrections), and 28001 (drainage of a bursa of the foot). We have mapped 175 ASC-relevant codes in this range, each with its own page.

What is the difference between CPT 28296 and 28297 for bunion surgery?

Both address hallux valgus, commonly called a bunion. The CMS short descriptors indicate that 28296 is a distal first metatarsal osteotomy, where the bone is cut and realigned, while 28297 is a first metatarsophalangeal joint arthrodesis, where the joint is fused. The right code depends on the operative technique documented by the surgeon. Confirm coverage and any prior-authorization requirements for each.
