Question:
Surgery of Primary Site--Melanoma: Which surgery codes should be used for cases that have a 1 cm margin? See Discussion.
Discussion:
For a melanoma case the surgery codes in the 30's are to be used when margins are stated to be less than 1 cm. The codes in the 40's are to be used for cases where the margins are greater than 1 cm.
Answer:
If the margin is exactly 1 cm, assign a surgery code from the 20-36 range. Use a code in the 40's only when the margin is greater than 1 cm.
