Unspecified open wound of unspecified part of neck, sequela

This code signifies a past open wound of the neck where the specific location and nature of the wound are not documented, and the patient is now experiencing a complication or late effect directly attributable to that previous injury. This could include chronic pain, scarring, nerve damage, or functional impairment resulting from the original trauma.

Use this code when documentation clearly indicates a sequela (late effect) of an unspecified open wound to an unspecified part of the neck, and the acute phase of the injury has passed. This code is appropriate when the medical record lacks sufficient detail to assign a more specific code for the original wound or its precise anatomical location.

• Always attempt to code to a more specific open wound code if documentation permits, including laterality and specific anatomical site.
• Ensure the documentation explicitly states a "sequela" or "late effect" and links it to a prior open neck wound.
• This code requires a seventh character of 'S' for sequela; do not use for initial encounter or subsequent encounter for active treatment.
