Posterior dislocation of right humerus, sequela

This code signifies a long-term complication or late effect stemming from a posterior dislocation of the right humerus. It indicates that the patient is experiencing residual issues directly attributable to a past injury where the head of the humerus was displaced backward from the glenoid cavity. These sequelae can manifest as chronic pain, instability, limited range of motion, or other persistent functional deficits.

Apply this code when documenting conditions that are a direct consequence of a previously healed or treated posterior dislocation of the right humerus. This includes follow-up encounters for chronic pain, stiffness, recurrent instability, or degenerative changes that developed as a result of the original injury. It should be used after the initial acute phase of the dislocation has passed.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, osteoarthritis).
• Ensure documentation clearly links the current condition to the prior posterior dislocation of the right humerus.
• The 7th character "S" indicates sequela and is crucial for proper code assignment.
