Explanation
Updated October 26, 2026
Advancement skin flap for a 2.1 to 5 cm defect on the face, neck or scalp, with undermining over 2.5 cm per side.
What it covers
Advancement flaps include undermining of more than 2.5 cm per side and include excision of a lesion when the flap is the closure technique (M17).
Defect 2.1 to 5 cm: R011 face, neck or scalp; R002 other areas. Defect 5.1 to 10 cm is R012/R003 (M17).
Billing rules
- Undermining must be more than 2.5 cm per side; S-plasty counts as simple excision, not a flap (M6, M17).
- When a benign, pre-malignant or malignant lesion excision is closed this way, claim this flap code instead of the excision code (M6, M17).
- Add E540 (+25%) once per lesion when the excision is done in hospital for tumour-free margins with frozen section, to the first flap or graft (M17).
- Procedures other than the skin flap, such as tendon grafts, are payable in addition (M17).
- The # prefix means the fee does not include premises, equipment, supplies and personnel at the place where the procedure itself is done (SP1).
- Assistant units are listed: a surgical assistant claims with suffix B (SP5 §21, GP85).
- Age premiums apply to surgical procedures for children: +30% under 30 days down to +10% for ages 5 to 15 (GP64).
Often billed with
- E540 frozen-section margin control in hospital (M17).
