    ICD-10-CM Code For Open Wound Of Head: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group S01 includes open wounds of the head such as lacerations, puncture wounds, and avulsions affecting the scalp, face, and external ear, with codes that specify location, depth, and laterality. These ICD-10-CM diagnosis codes are used to document traumatic head injuries, capturing details about wound type, involvement of adjacent structures, and any complicating factors relevant to clinical care. Accurate coding within the ICD-10-CM S01 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM S01: Open Wound Of Head Overview

    The ICD-10-CM S01 code group covers open wounds of the head, including lacerations, punctures, and avulsions that involve the scalp, skull, face, and external ear structures. These diagnoses target injuries to head soft tissue and superficial cranial structures resulting from trauma. Accurate coding matters for reimbursement because it captures the injury location, laterality, and severity, which affect claim adjudication and clinical record completeness.

    Typical Clinical Scenarios

    • A middle-aged construction worker presents to the emergency department after a fall from scaffolding with a deep laceration over the left parietal scalp that is actively bleeding and exposes subcutaneous tissue. He requires wound irrigation, local anesthesia, and layered closure in the ED; tetanus status is updated and imaging rules out skull fracture. An open wound of the scalp is coded from this group to capture an acute, traumatic penetrating laceration of the head. Typical codes: S01.11XA, S01.111A.
    • An elderly nursing home resident with fragile skin is brought to clinic for evaluation of a slowly enlarging non-healing ulceration of the forehead after repeated minor bumps over several weeks; there is no acute bleeding but the wound is exuding serous drainage and shows signs of chronicity. The clinician documents an open wound of the head with chronic status to guide wound care planning and to indicate delayed healing related to age and skin fragility. Typical codes: S01.119D, S01.149D.
    • A bicyclist involved in a road traffic collision arrives by ambulance with multiple injuries including an open facial laceration that had been previously repaired at an outside hospital but now shows wound infection and dehiscence requiring return to the operating room for repeat irrigation and closure. The encounter is coded to reflect a subsequent encounter for complications of an open head wound requiring surgical management. Typical codes: S01.10XD, S01.11XD.
