Displ assoc transv/post fx unsp acetab, 7thK

This code describes a fracture involving both the transverse and posterior columns of the acetabulum, which is the socket of the hip joint. The fracture fragments are not in their anatomical position (displaced), and the bone has failed to heal properly after an initial treatment (nonunion). This code is used for follow-up care related to this specific unhealed fracture.

Use this code for subsequent encounters when a patient is being treated for a previously diagnosed displaced associated transverse-posterior acetabular fracture that has not united. This includes follow-up appointments, evaluations for further treatment options for the nonunion, or management of complications directly related to the unhealed fracture.

• Requires an associated 7th character for the encounter type (e.g., K for subsequent encounter for fracture with nonunion).
• Ensure documentation clearly specifies both transverse and posterior column involvement and displacement.
• Distinguish from malunion (S32.463P) or routine follow-up for a healing fracture (S32.463D).
