ICD-10 Code L76.31 – Postprocedural hematoma of skin and subcutaneous tissue following a dermatologic procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L76.31 – Postprocedural hematoma of skin and subcutaneous tissue following a dermatologic procedure
What it is
L76.31 identifies a hematoma in the skin or subcutaneous tissue that develops after a dermatologic procedure. Use it when the record clearly links the bleeding collection to the skin procedure.
Clinical signs
Typical findings include localized swelling, bruising, tenderness, and a firm or fluctuant mass at the procedure site. Clinical features vary; refer to documentation for confirmation that the hematoma is postprocedural.
When to use this code
Use L76.31 when the provider documents a hematoma after a dermatologic procedure such as excision, biopsy, or other skin intervention. The note should show that the hematoma is a complication of the procedure, not a preexisting lesion. If the site or cause is unclear, check documentation.
Do not use for
Do not use this code for bruising or bleeding that is not documented as postprocedural. Do not use it for hematomas from trauma, anticoagulant use, or unrelated skin lesions unless the procedure link is clearly stated.
Coding tip
Code the complication only when the documentation connects the hematoma to the dermatologic procedure.
