Posterior subluxation of unspecified humerus, subs encntr

This code signifies a partial dislocation of the shoulder joint where the head of the humerus has slipped backward relative to the glenoid cavity, and the specific side (left or right) is not documented. It indicates that the patient is receiving follow-up care for this injury after the initial treatment phase.

Apply this code when a patient presents for ongoing management, such as physical therapy, cast changes, or follow-up evaluations, for a posterior subluxation of an unspecified shoulder that was previously diagnosed and treated. This code is appropriate for encounters occurring after the initial active treatment of the injury.

• Ensure documentation clearly states "subsequent encounter" or similar language indicating ongoing care.
• Only use this code when the laterality of the injury is not specified in the medical record.
• Pair with an external cause code (V00-Y99) if the cause of the injury is known and documented.
