Podiatry Billing Services Built Around Medicare's Foot Care Rules
We code and bill podiatry claims according to CMS routine foot care policy, Local Coverage Determinations, and the Q-modifier and class-findings documentation payers ask for before they pay — not after they deny.
Routine Foot Care Exclusions Cause Most Podiatry Denials
Medicare excludes routine foot care — nail trimming, corn and callus removal, hygienic care — from coverage under Section 1862(a)(13) of the Social Security Act, unless the patient has a qualifying systemic condition such as diabetes with peripheral neuropathy, peripheral vascular disease, or another condition listed in the applicable Local Coverage Determination. Getting paid for CPT 11055–11057 or 11719–11721 depends on documenting class findings (A, B, or C) and the treating physician for the underlying systemic condition, then attaching the correct Q7, Q8, or Q9 modifier to the claim.
We build every podiatry claim around this rule set first, because a technically correct CPT code still gets denied if the modifier, class findings, or referring physician information is missing or mismatched to the payer's LCD.
What We Check Before Every Claim Goes Out
- Qualifying systemic diagnosis is documented and linked to the foot care procedure
- Class findings (A/B/C) match the modifier billed
- Frequency limits for routine care (typically every 61 days) are not exceeded
- Referring/treating physician NPI is present when required by the LCD
- ABN is on file when a service is likely non-covered
What We Handle for Your Practice
ICD-10 and CPT Coding for Podiatric Procedures
We assign codes for nail debridement, bunionectomy (28290–28299), hammertoe repair (28285–28286), diabetic foot exams, orthotic fittings, and wound care, matching each procedure to the diagnosis that supports medical necessity.
Medicare LCD and Modifier Compliance
We apply Q7, Q8, Q9 modifiers based on documented class findings, and use GY or GZ modifiers correctly when a service is statutorily excluded or expected to be denied, so patients can be billed appropriately under an ABN.
Routine Foot Care Documentation Review
Before submission, we confirm the systemic condition, treating physician, and last-visit date fall within payer frequency rules, since most routine foot care denials trace back to a missing link between the podiatrist's note and the referring physician's record.
DME and Orthotics Billing
We handle claims for custom orthotics, diabetic shoes under the Therapeutic Shoe Bill, and ankle-foot orthoses, including the separate certifying physician statement Medicare requires for diabetic shoe claims.
Claim Submission and Clearinghouse Edits
Claims are scrubbed against payer-specific edits before submission, catching mismatched modifiers, missing frequency data, or invalid diagnosis pointers that would otherwise trigger a rejection at the clearinghouse level.
Denial Management and Appeals
When a claim is denied for CO-50 (not medically necessary) or CO-119 (frequency exceeded), we pull the chart note, confirm whether the denial is valid or an error, and file a corrected claim or appeal within the payer's filing deadline.
Accounts Receivable Follow-Up
We track claims past 30, 60, and 90 days, call payers on aged balances, and report back which claims are stuck in review versus which need a corrected resubmission.
Common Podiatry CPT Codes We Bill
| CPT Code | Description | Typical Modifier Need |
|---|---|---|
| 11055–11057 | Paring/cutting of corns and calluns | Q7/Q8/Q9 when systemic condition applies |
| 11719 | Trimming of non-dystrophic nails | Usually non-covered without qualifying diagnosis |
| 11720–11721 | Debridement of mycotic nails | Q7/Q8/Q9 based on class findings |
| 28285 | Hammertoe correction | RT/LT for laterality |
| 28296 | Bunionectomy with osteotomy | RT/LT for laterality |
| 29405 | Application of short leg cast | Bundled with E/M in some payer policies |
| G0127 | Trimming of dystrophic nails (non-physician) | Coverage varies by MAC |
Coverage rules and frequency limits vary by Medicare Administrative Contractor (MAC) and by commercial payer. We confirm the active LCD for your jurisdiction before billing.
Denial Reasons We See Most Often in Podiatry Billing
Usually caused by a routine foot care code billed without a documented qualifying systemic condition or missing class findings on the chart note.
Routine nail and callus care is generally limited to once every 61 days under Medicare policy; billing sooner without documented justification triggers this denial.
Claims for nail debridement or callus removal submitted without the Q7, Q8, or Q9 modifier are returned as incomplete, even when the underlying diagnosis supports coverage.
Certain E/M visits billed on the same day as a minor podiatric procedure are bundled unless modifier 25 is applied and supported by a separately documented evaluation.
Podiatry Billing FAQ
Do you bill Medicare and commercial payers, or only one?
We bill Medicare, Medicaid, and commercial payers. Since routine foot care coverage rules differ between Medicare's national policy and individual commercial plans, we track each payer's specific frequency and documentation requirements separately rather than applying one rule set to all claims.
What documentation do you need from our practice to bill correctly?
We need the podiatrist's chart note with class findings (A, B, or C), the name and NPI of the physician treating the qualifying systemic condition, and the date of the patient's last visit with that physician. Without these three items, a routine foot care claim is likely to be denied regardless of how the CPT code is billed.
Can you help with claims that were already denied before we started working with you?
Yes. We review the original claim, the denial code, and the chart documentation to determine whether the denial was valid or an error, then file a corrected claim or a formal appeal within the payer's filing deadline, which is typically 90 to 180 days depending on the payer.
Do you handle DME billing for diabetic shoes and orthotics separately?
Yes. Diabetic shoe billing under the Therapeutic Shoe Bill requires a separate certifying statement from the physician managing the patient's diabetes, in addition to the podiatrist's fitting note. We track both documents before submitting the claim.
How do you charge for podiatry billing services?
Pricing is based on claim volume and scope of work, typically structured as a percentage of collections or a flat monthly rate. We provide a specific quote after reviewing your current claim volume and payer mix.
