Top 10 Things to Know About Podiatry Medical Billing
Podiatry medical billing comes with its own unique challenges—Medicare rules, coverage limitations, and the complexity of foot care procedures. One small oversight in coding or documentation can mean the difference between timely reimbursement and a denied claim.
Here are the Top 10 most important things you need to know about podiatry billing in 2025.
1. Routine Foot Care Often Isn’t Reimbursable
Basic services like nail trimming or callus removal are considered routine and not billable unless medically necessary.
Medicare requires an underlying systemic condition and specific clinical findings.
Tip: Document conditions like diabetic peripheral neuropathy (E11.42) and use proper ICD-10 codes.
2. Use Q Modifiers for Foot Care Eligibility
Q modifiers signal the severity of foot findings. They're essential when billing Medicare for routine foot care services.
Q7 – One class A finding
Q8 – Two class B findings
Q9 – One class B and two class C findings
They validate medical necessity and help avoid denials.
3. Nail Avulsions and Matrixectomies Have Different Codes
Don't mix them up.
11730 – Nail avulsion (simple)
11750 – Nail excision with matrixectomy
Incorrect use of these CPT codes often results in undercoding or overcoding.
4. Modifiers Matter—A Lot
Modifiers tell payers how services relate to each other.
In podiatry, improper modifier use is a top cause of denials.
Commonly used ones include:
-25 for separate E/M service
-59 for distinct procedural service
-GA to show an ABN is on file
-76 for repeat procedures
5. Ulcer Debridement Billing Depends on Depth
The depth of the wound debrided determines the CPT code. Documentation must reflect the exact tissue removed.
| CPT Code | Tissue Debrided |
|---|---|
| 11042 | Subcutaneous tissue |
| 11043 | Muscle |
| 11044 | Bone |
6. Always Check Medicare LCDs and NCDs
Medicare’s Local Coverage Determinations (LCDs) define when services like nail care or foot exams are covered.
‘‘Billing without checking the LCD can lead to blanket denials—even when procedures are done correctly.’’
7. Global Period Rules Must Be Understood
Surgical podiatry procedures often include global periods, during which follow-ups are not separately billable.
For example:
11730 – Has a 10-day global period
11750 – Also has a 10-day period
Any billing during this time must be justified with clear documentation.
8. Podiatry DME Billing Requires Extra Attention
Billing for diabetic shoes and inserts? Use HCPCS codes like A5500–A5513 and ensure a prescription and medical records are available for audits.
‘‘Missing proof of medical necessity is a common reason for DME denials in podiatry.’’
9. ICD-10 Specificity is Mandatory
Unspecified diagnoses (like L97.9) can trigger rejections. Be as specific as possible.
Instead of:
‘‘L97.9 – Non-pressure ulcer, unspecified
Use:
L97.413 – Non-pressure ulcer of right heel with necrosis of muscle’’
10. Documentation is Your Lifesaver
Insurance audits in podiatry are rising. If your notes don’t justify the CPT and ICD-10 codes, the claim won’t stand.
Checklist for each encounter:
Medical necessity
Procedure details
Modifiers (if applicable)
Global period awareness
Supporting diagnosis codes
