Postural lordosis, lumbar region

This code signifies an abnormal anterior curvature of the lumbar spine that is correctable and often related to posture. It is characterized by an exaggerated inward curve of the lower back, which typically resolves when the patient changes position or lies down. This condition is distinct from fixed structural deformities of the spine.

Use this code when documentation clearly indicates a diagnosis of postural lordosis specifically affecting the lumbar region. This diagnosis is often made based on physical examination findings, where the lordosis is observed to be flexible and reducible. Supporting documentation would include notes describing the patient's posture, the flexibility of the spinal curve, and the absence of fixed structural changes.

• Differentiate from fixed lordosis (e.g., M40.5x) which implies a structural deformity not correctable by posture.
• Ensure the documentation specifies "postural" and "lumbar region" to accurately assign this code.
• Do not use this code for normal physiological lumbar lordosis; it is reserved for an abnormal postural exaggeration.
