Lordosis, unspecified, lumbosacral region

This code signifies an abnormal inward curvature of the spine in the lower back (lumbar) and sacral regions, where the specific type or cause of the lordosis is not documented. It represents a postural deviation that can lead to back pain and functional limitations.

Use this code when documentation indicates lordosis affecting the lumbosacral spine, but the provider has not specified the type (e.g., congenital, post-laminectomy, secondary to other conditions). This code is appropriate when the medical record simply states "lumbosacral lordosis" without further detail.

• Avoid using this code if a more specific type of lordosis (e.g., M40.45 for post-laminectomy lordosis, lumbosacral region) is documented.
• Query the provider for clarification if the documentation mentions a cause or type of lordosis that could lead to a more specific code.
• This code should be sequenced as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when it is a co-morbidity.
