Postural lordosis, lumbosacral region

This code signifies an abnormal inward curvature of the spine specifically in the lower back and sacral area, which is exacerbated or primarily evident when the patient is standing or in an upright position. It represents a non-fixed lordosis that often resolves or significantly reduces when the patient lies down.

Apply this code when documentation clearly indicates a diagnosis of postural lordosis affecting the lumbosacral region. This diagnosis is typically made based on physical examination findings that demonstrate increased lumbar lordosis that is correctable or significantly reduced in a supine position, differentiating it from structural lordosis.

• Ensure documentation specifies "postural" lordosis to distinguish it from other types.
• Confirm the affected region is explicitly stated as lumbosacral; avoid using for thoracic or unspecified regions.
• Do not confuse with M40.5- (Lordosis, unspecified), which lacks the specificity of postural and region.
