ICD-10 code for radiculopathy

About coding radiculopathy
The ICD-10-CM code for radiculopathy is M54.10 (Radiculopathy, site unspecified). The official index lists 17 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M54.10.
Within M54.1, choose M54.10 (site unspecified) only when documentation doesn't support a more specific option: occipito-atlanto-axial region (M54.11), cervical region (M54.12), cervicothoracic region (M54.13), thoracic region (M54.14), thoracolumbar region (M54.15), lumbar region (M54.16), lumbosacral region (M54.17) and sacral and sacrococcygeal region (M54.18).
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 073 (Cranial and Peripheral Nerve Disorders with MCC, relative weight 1.5779) and DRG 074 (Cranial and Peripheral Nerve Disorders without MCC, relative weight 1.0173), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
