M40.50 identifies lordosis (excessive inward spinal curvature) that is unspecified in both type and anatomic site. Use it only when documentation fails to name either the spinal region or the etiology of the curvature.
Abnormal anterior curvature (hyperlordosis or loss of normal curve) affecting the thoracolumbar junction — the transitional zone where the thoracic and lumbar spine meet — with etiology not further specified in the clinical record.
M40.56 identifies lumbar lordosis of unspecified type — meaning the provider has documented exaggerated inward curvature of the lumbar spine but has not specified whether the cause is postural, positional, or associated with an underlying condition.
Unspecified lordosis localized to the lumbosacral region, representing an abnormal anterior curvature at the L5-S1 junction without a documented specific etiology or subtype.
