What 11644 covers

This code covers excision of a malignant skin lesion on the face, ears, eyelids, nose, or lips, including the margins taken around it. Dermatologists commonly perform these procedures in an office or outpatient setting; plastic surgeons and ophthalmologists may perform them for lesions in their respective areas. The size category is based on the lesion’s greatest diameter plus the narrowest margins needed for complete removal, measured before excision—not the resulting wound or specimen after removal.

Report the code when the documented site and excised diameter including margins fit this category. Record the lesion location, measurement, and malignant diagnosis; pathology findings can support the diagnosis. Simple closure is included, while a separately documented intermediate or complex repair may be reported separately. CMS assigns a 10-day global period, so related postoperative visits during that period are included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment is statutorily restricted, and co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

11644 billing questions

How is the 3.1-4 cm size determined?

Measure the lesion’s greatest diameter together with the narrowest margins needed for complete removal, before excision. Do not use the postoperative defect or specimen dimensions.

How does this differ from code 11643?

Both codes cover the same anatomic sites and malignant-lesion excision. Choose 11644 when the lesion plus margins measures 3.1-4 cm; 11643 is for the smaller size band.

Is closure included in this code?

Simple closure is included. A separately documented intermediate or complex repair may be reported when the repair service meets the applicable criteria.

Can modifier 50 be used for lesions on both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code; modifier 50 should not be used.

Are postoperative visits included?

Related postoperative visits during the 10-day global period are included in the procedure payment.

How does CMS handle other procedures performed in the same session?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%. Assistant-at-surgery payment is statutorily restricted; co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
