Acquired deformity of pelvis

This code represents a non-congenital structural abnormality of the pelvic bones that has developed over time due to various causes such as trauma, disease, or degenerative processes. It signifies a deviation from the normal anatomical shape and alignment of the pelvis, which can lead to functional impairment or pain.

Use this code when documentation clearly indicates an acquired, rather than congenital, deformity of the pelvis. This includes conditions like post-traumatic pelvic asymmetry, pelvic malunion after fracture, or deformities resulting from metabolic bone diseases. Supporting documentation should specify the acquired nature of the deformity.

• Differentiate carefully between acquired and congenital pelvic deformities; congenital conditions are coded elsewhere.
• Ensure documentation specifies the cause of the acquired deformity if known, as this may require additional codes.
• Do not use this code for maternal care related to cephalopelvic disproportion, as indicated by the Excludes1 note.
