Podiatry has some of the most specific Medicare documentation requirements in any specialty — particularly around routine foot care. Class findings, systemic conditions, and the "at-risk" patient designation must be documented precisely or claims deny. We know every requirement.
Common Billing Challenges
These are the billing failure points we see most often in podiatry practices — and the ones our team resolves systematically from day one.
Medicare covers routine foot care (11055-11057, 11719-11721) ONLY when the patient has a systemic condition (diabetes, PVD, peripheral neuropathy) documented with specific class findings. Missing or generic documentation = automatic denial.
Nail avulsion (11730/11732) vs. nail debridement (11720/11721) vs. mycotic nail (11720 with Q modifier) are distinct codes with different coverage rules. Incorrect selection affects both reimbursement and audit risk.
Bunion surgery (28290-28299) has a 90-day global period during which follow-up is included in the surgical fee. Separately billing E/M visits within the global period without proper modifiers (24, 25, 57) causes automatic denials.
Annual diabetic foot exams (G0245/G0246) require specific documentation of examination findings beyond a routine physical. Vascular, neurological, and dermatological findings must each be documented to support the code.
Custom foot orthotics (L3000-L3649) require a specific diagnosis, physician order, detailed measurement records, and proof of dispensing. Payers apply strict documentation review — template orders without individualized measurements are routinely denied.
Corticosteroid injections for plantar fasciitis (20550/20551) require documentation of conservative treatment failure. Without evidence of prior stretching, physical therapy, or NSAIDs, medical necessity is disputed by most payers.
Key Procedure Codes
Our coders hold specialty-specific credentials and train continuously on the codes that drive the most revenue — and the most denials — in podiatry.
| CPT Code | Description | Common Issue |
|---|---|---|
| 11721 | Debridement nails, 6+ | Q modifier required for mycotic nails with systemic condition |
| 11730 | Nail avulsion, single | Documentation of indication distinguishes from debridement |
| 28292 | Bunionectomy, Keller/Mayo | Global period 90 days; E/M within global requires mod 24 |
| G0245 | Initial diabetic foot exam | Specific component documentation required by CMS |
| 20550 | Injection tendon sheath | Failed conservative care documentation required |
| L3000 | Foot insert, molded to patient | Custom vs. prefab distinction determines reimbursement |
