Posterior subluxation of unspecified hip, sequela

This code indicates a past posterior displacement of the hip joint where the femoral head partially slipped out of the acetabulum, and the specific hip (left or right) is not documented. It is used to report the long-term effects or complications resulting from this previous injury, not the acute event itself.

Apply this code when documenting residual symptoms, chronic pain, instability, or functional limitations that are directly attributable to a prior posterior hip subluxation. This is appropriate for follow-up visits or when the patient presents with ongoing issues related to an old injury, and the laterality of the hip is unknown or unspecified in the medical record.

• Only use this code for sequelae (late effects) of a resolved posterior hip subluxation, not for an acute or current subluxation.
• Ensure documentation clearly links the current condition to a past posterior hip subluxation.
• If the laterality (left or right) of the affected hip is specified in the medical record, a more specific code should be used.
