Posterior dislocation of left humerus, sequela

This code signifies a long-term complication or residual effect stemming from a past posterior dislocation of the left shoulder joint. These sequelae can include chronic pain, instability, limited range of motion, or degenerative changes that persist after the initial injury has healed.

Apply this code when documenting ongoing issues directly attributable to a previously sustained posterior dislocation of the left humerus. This is appropriate for follow-up visits where the patient is being treated for the chronic consequences, rather than the acute injury itself.

• Always link this sequela code to an external cause code (V00-Y99) if the original injury's cause is known and relevant to the current encounter.
• Do not use this code for an acute or initial posterior dislocation; use the appropriate acute injury code.
• Consider additional codes for specific sequelae, such as chronic pain (e.g., G89.29) or specific functional limitations, if documented.
