What this code covers

Source · Editorial summary grounded in 3 cited references ↓

11057 is used when five or more hyperkeratotic lesions are pared at one visit. It is billed once, no matter how many lesions above four.

It is mostly a podiatry code, though foot and ankle practices with a diabetic foot clinic will see it. Patients with severe neuropathy or deformity often have many calluses at once. Medicare coverage follows the same routine foot care rules as 11055 and 11056: qualifying systemic condition, class findings, and the matching Q modifier.

Because 11057 is the top of the series, payers look closely at whether five or more lesions really were treated. List each lesion by site. Do not count a single large callus as multiple lesions. If you also debride nails, those codes are separate. If the patient has no qualifying condition, it is excluded and should be billed with GY or to the patient under your financial policy.

Work RVU vs. total RVU

The work RVU (0.63) is the surgeon's own effort — the figure physician pay and productivity targets are built on. The total RVU (2.66) adds practice overhead and malpractice, and is what drives the Medicare payment below.

Work RVU	0.63
Practice expense RVU	1.98
Malpractice RVU	0.05
Total RVU	2.66
Medicare national rate	$88.85
Global period	0 days

Payment by site of service
