Hair causing external constriction, sequela

This code describes a long-term complication or residual effect resulting from hair causing external constriction. This could involve chronic tissue damage, nerve impairment, or other persistent issues that arose from a previous incident where hair constricted a body part.

Apply this code when documenting a patient presenting with a current health problem directly attributable to a past episode of hair-induced external constriction. This is appropriate for follow-up visits or when the sequela is the primary reason for the encounter, such as chronic pain, scarring, or functional limitations from a "hair tourniquet" injury.

• Requires a seventh character 'S' for sequela, indicating a late effect.
• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic pain, scar).
• Ensure documentation clearly links the current condition to a past hair constriction event.
