Sprain of left acromioclavicular joint, sequela

This code signifies a chronic or late-effect injury to the left acromioclavicular (AC) joint, specifically a sprain, that is no longer in the acute phase of healing. It indicates persistent symptoms or complications arising from a previously sustained AC joint sprain on the left side.

Use this code when documenting ongoing pain, instability, limited range of motion, or other long-term issues directly attributable to a past sprain of the left AC joint. This applies to patients presenting for evaluation or treatment of these residual problems, typically after the initial injury has healed.

• Ensure documentation clearly links the current symptoms to a prior left AC joint sprain.
• This "S" seventh character indicates a sequela, meaning the patient is presenting for treatment of a residual effect or complication of the initial injury.
• Do not use this code for acute or initial encounters for a left AC joint sprain.
