External constriction of unspecified upper arm, sequela

This code indicates a long-term or late effect resulting from external pressure or compression on an unspecified part of the upper arm. This constriction could be due to various external factors that have caused lasting damage or functional impairment.

Apply this code when documenting a chronic condition or residual problem in the upper arm that is a direct consequence of a past external constriction injury. This is appropriate for follow-up encounters after the initial injury has healed, but its effects persist.

• Always use this code as a secondary diagnosis, following the code for the primary sequela condition.
• Ensure documentation clearly links the current upper arm condition to a previous external constriction event.
• Do not use for acute or initial external constriction injuries; this code is specifically for sequelae.
