Medicare routine foot care

Our podiatrist removed an ingrown toenail on a Medicare patient. Diagnoses were ingrown toenail, onychia, paronychia. My billing company is telling me this procedure (11730) is routine foot care. Is that correct?

Avulsion of a nail (CPT codes 11730/11732) involves the separation and removal of a border of, or the entire nail, from the nail bed to the eponychium. In order for this procedure to be considered a nail avulsion, it must be performed using an injectable anesthesia except in the instances in which a patient is devoid of sensation or there are extenuating circumstances in which injectable anesthesia is not required or is medically contraindicated. Part or all of one nail plate is removed or avulsed in this procedure. For total nail avulsion, an elevator is placed under the proximal nail fold and pushed in a back and forth motion to separate it totally from the underlying nail plate. The elevator is removed and then inserted under the proximal end of the nail using a similar action to separate it from the nail bed. The loosened nail is lifted, one end is grasped with a hemostat, and, using a side-to-side rolling action, the nail is removed. The surgical treatment of nails is covered for the following indications: Onychocryptosis (ingrown nails); Subungal abscess; Contusion of the toenail or fingernail; Crushing injury of the toes or fingers; Paronychia; Complicated wounds of the toes involving nail components; Deformed nails that prevent wearing shoes or otherwise jeopardize the integrity of the toe.
Treatment of simple onychocryptosis with removal of the offending wing or spicule of the nail is considered to be routine foot care in the absence of infection or inflammation. Trimming, cutting, clipping, or debriding of a nail, distal to the eponychium, will be regarded as routine foot care.
Diagnosis and documentation will make or break your case.

COuld this be..

a case where more is not better? If routine foot care is not covered, don't include codes for it. Bill for the procedure and 703.0.
