M54.0Panniculitis affecting regions of neck and back

M54.0 is the ICD-10-CM diagnosis code for panniculitis affecting regions of neck and back. 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 10 subcodes must be used instead.

Within M54 (dorsalgia), M54.0 is specifically for panniculitis affecting regions of neck and back. Related codes cover radiculopathy (M54.1), Cervicalgia (M54.2), sciatica (M54.3), 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: M54.00 (site unspecified), M54.01 (occipito-atlanto-axial region), M54.02 (cervical region), M54.03 (cervicothoracic region), M54.04 (thoracic region), M54.05 (thoracolumbar region), M54.06 (lumbar region), M54.07 (lumbosacral region) and 2 more.

Don't report M54.0 together with the conditions in its Excludes1 note: lupus panniculitis (L93.2), panniculitis NOS (M79.3) and relapsing [Weber-Christian] panniculitis (M35.6).

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