About M54.3

M54.3 is the ICD-10-CM diagnosis code for 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), M54.3 is specifically for sciatica. Related codes cover panniculitis affecting regions of neck and back (M54.0), radiculopathy (M54.1), Cervicalgia (M54.2), Lumbago with sciatica (M54.4), 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: M54.30 (unspecified side), M54.31 (right side) and M54.32 (left side).

Don't report M54.3 together with the conditions in its Excludes1 note: intervertebral disc degeneration, lumbar region with lower extremity pain only (M51.361), intervertebral disc degeneration, lumbosacral region with lower extremity pain only (M51.371), lesion of sciatic nerve (G57.0), sciatica due to intervertebral disc disorder (M51.1-) and 1 more.

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