ICD-10-CM L76.31: Postprocedural hematoma of skin and subcutaneous tissue following a dermatologic procedure

ICD-10-CM code L76.31 identifies a postprocedural hematoma of the skin and subcutaneous tissue that occurs following a dermatologic procedure. The code is an active terminology concept and falls under a broader parent category for postprocedural hematomas and seromas of the skin following a procedure. 1 4

Plain-language overview

Code L76.31 is an active terminology concept representing a pathologic function involving a postprocedural hematoma of the skin and subcutaneous tissue following a dermatologic procedure. 1

What this code represents

The official display label for L76.31 is postprocedural hematoma of skin and subcutaneous tissue following a dermatologic procedure, and the concept's semantic type is a pathologic function. 1

Coding details

In the ICD-10-CM hierarchy, L76.31 is a narrower concept under the parent code L76.3, which covers postprocedural hematoma and seroma of skin and subcutaneous tissue following a procedure. 1 4

Code L76.31 is distinct from L76.32, which is used for postprocedural hematoma of skin and subcutaneous tissue following other procedures, and from L76.33, which covers postprocedural seroma following a dermatologic procedure. 4

Documentation considerations

The official terminology for L76.31 specifies that the hematoma occurs in the skin and subcutaneous tissue and explicitly follows a dermatologic procedure. 1

What the sources add

While one terminology source defines L76.31 as an active concept with a pathologic function semantic type, another coding source places it within a list of related postprocedural skin complications like hemorrhage and seroma. 1 4

A federal manual includes postprocedural hemorrhage and hematoma of skin and subcutaneous tissue following a dermatologic procedure within broader diagnostic definitions, distinguishing it from intraoperative hemorrhage complicating a dermatologic procedure. 2

Coverage and utilization context

A Medicare billing and coding article references L76.31 within materials related to the incision and drainage of abscesses of the skin, subcutaneous, and accessory structures. 3

Questions to verify

The available sources do not detail the clinical criteria needed to distinguish dermatologic procedures from other interventions, leaving the specific definition of a dermatologic procedure unestablished. 1 4
