We recently have been getting denials from Medicare for routine foot care services 11721, 11056 for denial code 151. ( information submitted does not support this many/frequency of service). The patient Dx is I90.91, which has been paid for on previous visits and the timing is greater than 61 days.
For CPT codes 11056 &11721, if the charges are denied for frequency, I would check to see if the patient was seen by another podiatrist. If Medicare customer service is contacted, they will confirm if another provider has treated the patient for those service that would trigger that denial.
