About coding neck panniculitis
The ICD-10-CM code for neck panniculitis is M54.02 (Panniculitis affecting regions of neck and back, cervical region). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M54.02.
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.
