Subluxation complex (vertebral) of pelvic region

This code signifies a vertebral subluxation complex affecting the pelvic region, specifically the sacrum or ilium. It describes a functional biomechanical lesion characterized by altered joint motion, segmental dysfunction, and potential neurological involvement, without frank dislocation.

Use this code when documentation indicates a sacral or iliac subluxation complex identified through physical examination findings such as restricted joint play, tenderness, or asymmetry. This code is appropriate for chiropractic, osteopathic, and other manual medicine encounters addressing these biomechanical dysfunctions.

• Ensure documentation clearly specifies the "pelvic region" to differentiate from other spinal subluxations.
• Do not confuse with codes for frank dislocations (e.g., S33.1XXA for dislocation of sacrum).
• This code is often a primary diagnosis for chiropractic manipulative treatment (CMT) services.
