M54.4Lumbago with sciatica

M54.4 is the ICD-10-CM diagnosis code for Lumbago with sciatica. It belongs to category M54 (dorsalgia), block M50-M54 (other dorsopathies) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within M54 (dorsalgia), M54.4 is specifically for Lumbago with sciatica. Related codes cover panniculitis affecting regions of neck and back (M54.0), radiculopathy (M54.1), Cervicalgia (M54.2), sciatica (M54.3), low back pain (M54.5), pain in thoracic spine (M54.6), other dorsalgia (M54.8) and unspecified (M54.9).

To report this condition, pick the subcode that matches the documentation: M54.40 (unspecified side), M54.41 (right side) and M54.42 (left side).

Don't report M54.4 together with the conditions in its Excludes1 note: intervertebral disc degeneration, lumbar region with discogenic back pain and lower extremity pain (M51.362), intervertebral disc degeneration, lumbosacral region with discogenic back pain and lower extremity pain (M51.372) and lumbago with sciatica due to intervertebral disc disorder (M51.1-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
