About M54.02
M54.02 is the ICD-10-CM diagnosis code for panniculitis affecting regions of neck and back, cervical region. It belongs to category M54 (dorsalgia), block M50-M54 (other dorsopathies) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within M54.0 (panniculitis affecting regions of neck and back), M54.02 is specifically for panniculitis affecting regions of neck and back, cervical region. Related codes cover site unspecified (M54.00), occipito-atlanto-axial region (M54.01), cervicothoracic region (M54.03), thoracic region (M54.04), thoracolumbar region (M54.05), lumbar region (M54.06), lumbosacral region (M54.07), sacral and sacrococcygeal region (M54.08) and 1 more.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 606 (Minor Skin Disorders with MCC, relative weight 1.5728) and DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 723.6 (panniculitis specified as affecting neck).
