Avulsion of scalp, initial encounter

This code signifies a complete or partial tearing away of the scalp from the underlying skull, often due to significant trauma. It represents a severe soft tissue injury involving the entire thickness of the scalp, including skin, subcutaneous tissue, and galea aponeurotica.

Apply this code for initial encounters involving patients presenting with a traumatic avulsion of the scalp. Documentation should clearly describe the scalp tissue being torn away or detached, rather than just a laceration or abrasion. This code is appropriate for emergency department visits or initial hospital admissions for this injury.

• Ensure documentation specifies "avulsion" and not just a deep laceration or degloving injury without complete detachment.
• Always assign an external cause code (V00-Y99) to describe the circumstances of the injury.
• Consider additional codes for associated skull fractures, intracranial injuries, or open wounds if present.
