Postproc hematoma of skin, subcu fol a dermatologic proc

This code signifies the development of a localized collection of blood outside of blood vessels, occurring within the skin or the tissue directly beneath it, as a direct complication of a dermatologic intervention. It represents a post-surgical bleeding event that manifests as a bruise or swelling after a procedure involving the skin.

Apply this code when documentation clearly indicates a hematoma formed in the skin or subcutaneous tissue subsequent to a dermatologic procedure (e.g., biopsy, excision, cryotherapy). The physician's notes should explicitly state the presence of a hematoma and link it to the recent skin procedure.

• Always sequence this code after the code for the underlying dermatologic procedure, if applicable, or as a primary diagnosis if the patient presents solely for hematoma management.
• Ensure the documentation specifies "dermatologic procedure" to differentiate from hematomas following other types of interventions.
• Distinguish from ecchymosis (bruising) that is not a significant collection of blood requiring intervention; this code implies a more substantial hematoma.
