External constriction of unspecified ear, sequela

This code indicates a long-term effect or complication resulting from external constriction of an unspecified ear. This could include chronic pain, deformity, or functional impairment that persists after the initial constricting force has been removed or healed. It signifies that the original injury is no longer acute but has left a lasting impact.

Apply this code when documentation clearly states a sequela (late effect) due to external constriction of the ear, and the specific ear (left or right) is not documented. This is appropriate for follow-up encounters addressing chronic issues stemming from a past constrictive injury. Ensure the medical record explicitly links the current condition to a previous external constriction.

• Requires a seventh character 'S' to denote sequela, indicating a late effect.
• Do not use for acute injuries; instead, use an acute injury code from the S00.44- series.
• Always sequence the sequela code first, followed by codes for the specific manifestation(s) of the sequela (e.g., chronic pain, scar formation).
