What Counts As Routine Foot Care
Routine foot care includes cutting or removing corns and calluses, trimming and debriding nails, and other hygienic or preventive care. The common codes are 11055 to 11057 for paring corns and calluses, 11719 for trimming non-dystrophic nails, G0127 for trimming dystrophic nails, and 11720 and 11721 for nail debridement.
The Systemic Condition Exception
Medicare pays for routine foot care when the patient has a systemic condition, such as diabetes with peripheral involvement or peripheral vascular disease, that creates a risk of harm if a non-professional performed the care. The condition and the qualifying findings must be documented. For some conditions, the patient must also be under the active care of a physician (MD or DO) for that condition, and the claim should identify that physician and the approximate date the patient was last seen, which must be within the prior six months.
The Class Findings
- Class A: non-traumatic amputation of the foot or an integral skeletal portion of it
- Class B: absent posterior tibial pulse, absent dorsalis pedis pulse, or advanced trophic changes (three are required, such as decreased hair growth, nail thickening, pigmentary changes, thin and shiny skin, or rubor)
- Class C: claudication, temperature changes such as cold feet, edema, paresthesias, or burning
Choosing The Q Modifier
- Q7: one Class A finding
- Q8: two Class B findings
- Q9: one Class B finding and two Class C findings
Frequency
Many MAC policies consider routine foot care reasonable about once every 61 days unless the record documents a need for more frequent care. Billing on a fixed short cycle without that documentation is a common audit target.
Frequently Asked Questions
- Does a diabetes diagnosis alone qualify the patient?
- No. The diagnosis must be accompanied by documented class findings or other qualifying evidence of risk, and the matching Q modifier on the claim.
- What if the patient wants care that Medicare will not cover?
- Routine foot care without qualifying findings is statutorily excluded. The patient can be billed directly, and the GY modifier identifies the service as excluded.
