Posterior subluxation of left humerus, sequela

This code signifies a chronic or late-effect condition where the left humerus has partially dislocated backward from the glenoid cavity. This subluxation is not an acute injury but rather a residual problem or complication stemming from a previous injury or condition. The "sequela" designation indicates that the current issue is a long-term consequence.

Use this code when documenting a patient presenting with ongoing symptoms or findings related to a prior posterior subluxation of the left humerus. This would include cases where the patient has chronic pain, instability, or limited range of motion directly attributable to the old injury. It is appropriate for follow-up visits addressing the long-term management of such a condition.

• Always assign a "sequela" code as a secondary diagnosis, with the primary diagnosis reflecting the current manifestation or reason for the encounter.
• Ensure documentation clearly links the current posterior subluxation to a previous injury or condition.
• Do not use this code for acute or initial encounters for a posterior subluxation; those would require an acute injury code.
