Subluxation of unspecified acromioclavicular joint, sequela

This code indicates a partial dislocation of the acromioclavicular (AC) joint that occurred in the past and is now causing ongoing symptoms or complications. It signifies a long-term effect or residual condition stemming from an earlier AC joint subluxation, where the specific side (left or right) of the body is not documented.

Use this code for patients presenting with chronic pain, limited range of motion, instability, or other persistent issues directly attributable to a previously sustained AC joint subluxation. This applies when the initial injury has healed, but its lasting impact is being treated or evaluated, and the laterality is not specified in the medical record.

• Always look for documentation explicitly stating "sequela," "late effect," or chronic conditions resulting from a past AC joint injury.
• Ensure the medical record does not specify laterality (left or right) for the AC joint; if it does, a more specific code should be used.
• This code should be used as a secondary diagnosis when the primary reason for the encounter is the management of the sequela.
