Questions About L72.0Overview
What is the ICD-10 code for epidermal cyst?
The ICD-10-CM code for epidermal cyst is L72.0 (sometimes written as L720). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is L72.0 (Follicular cysts of skin and subcutaneous tissue) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report epidermal cyst on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does L72.0 group to?
When epidermal cyst is the principal diagnosis on an inpatient stay, it groups to MS-DRG 607, 606, with relative weights from 0.8772 to 1.5721 depending on complications. Higher weights mean higher Medicare reimbursement.
Can L72.0 be reported with a code from Q84?
Not as a rule. The Excludes1 note at block L60-L75, which applies to L72.0, lists "congenital malformations of integument (Q84.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
What is the ICD-9 equivalent of L72.0?
Under the General Equivalence Mappings, epidermal cyst converts to ICD-9-CM 706.2 (sebaceous cyst). The mapping is approximate, so confirm the match fits the documentation.
