Billable codes in this category
Each of the codes below is billable. Choose the one that most accurately describes the patient's diagnosis.
Postural lordosis with no specific spinal region documented — an acquired, posture-driven exaggeration of the normal inward spinal curve, coded when the clinical note does not identify the affected region (thoracolumbar, lumbar, or lumbosacral).
Acquired anterior spinal curvature localized to the thoracolumbar junction (T10–L2 region) that arises from postural habits rather than structural or congenital deformity.
Acquired exaggeration of the lumbar inward curve (hyperlordosis) attributable to posture rather than a structural vertebral abnormality or congenital cause.
Acquired, posture-driven hyperlordosis localized to the lumbosacral junction (L5–S1 region), distinguished from congenital lordosis and from lordosis caused by prior surgery.
