Podiatric billing requires careful attention to foot and ankle anatomy, diabetic foot care rules, and nail debridement frequency policies. This page covers the most frequently billed ICD-10-CM diagnosis codes and CPT procedure codes used by podiatrists across the United States.
Routine nail debridement (11721) requires a ‘class findings’ diagnosis for Medicare coverage — document systemic conditions like diabetes, PVD, or poor circulation that impair self-care.
Diabetic foot ulcer codes (E11.621) require the diabetes code first (E11.x) followed by the ulcer site code (L97.x) as an additional code.
Bunion correction CPT codes (28296 vs 28299) differ by technique — the operative note must specify the procedure performed.
Orthotics (L codes, HCPCS) require a detailed written order from the treating physician and proof of medical necessity before billing.
M77.30 is calcaneal spur, unspecified foot — this is the most commonly used code for plantar fasciitis billing. M72.2 (Plantar fascial fibromatosis) is a separate, distinct condition. Some coders use M79.671 (foot pain) as an additional code to support the clinical picture.
What is the class findings requirement for routine nail debridement?
Medicare requires documented Class A findings (absent pedal pulse, claudication, trophic changes) or Class B findings (diabetes, PVD, peripheral neuropathy) to support medical necessity for 11720/11721. Without a qualifying systemic condition, routine nail care is not covered by Medicare.
Is E11.621 coded as primary or secondary?
E11.621 (Type 2 DM with foot ulcer) should be coded as the primary diagnosis when the diabetic foot ulcer is the reason for the encounter. Add the site-specific ulcer code (L97.x) as an additional code to specify location and depth.
What CPT is used for bunion surgery?
28296 is the most common code for hallux valgus correction with distal metatarsal osteotomy (Chevron procedure). 28299 is for complex bunion corrections. The operative note must document the exact osteotomy technique to support the code selected.
