Posterior dislocation of unspecified hip, sequela

This code indicates a long-term complication or residual effect stemming from a posterior dislocation of an unspecified hip joint. It signifies that the initial injury has resolved, but the patient continues to experience issues directly attributable to that past dislocation.

Use this code when documenting conditions such as chronic pain, instability, limited range of motion, or degenerative changes in the hip joint that are a direct consequence of a previously treated posterior hip dislocation. This code is appropriate when the acute phase of the dislocation has passed, and the current encounter addresses these lasting effects.

• Always assign a secondary code to describe the specific nature of the sequela (e.g., M16.1 for other primary coxarthrosis, unilateral).
• Ensure documentation clearly links the current condition to the previous posterior hip dislocation.
• This code should not be used for acute or subacute dislocations; use the appropriate acute dislocation code for those encounters.
