Coding an Epidermal Inclusion Cyst

Coding an Epidermal Inclusion Cyst

April 1, 2021

Question:
I excised an EIC lesion on the chest.  I coded this as D48.5 but my coder says this is the wrong diagnosis code.  What is the correct diagnosis code?

Answer:
ICD-10-CM code D48.5 (Neoplasm of uncertain behavior of skin) is incorrect as you have stated the patient has an EIC (epidermal inclusion cyst). You should report L72.0, (Epidermal cyst).
