About coding thoracic neuritis
The ICD-10-CM code for thoracic neuritis is M54.14 (Radiculopathy, thoracic region).
Within M54.1 (radiculopathy), M54.14 is specifically for radiculopathy, thoracic region. Related codes cover site unspecified (M54.10), occipito-atlanto-axial region (M54.11), cervical region (M54.12), cervicothoracic region (M54.13), 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 551 (Medical Back Problems with MCC, relative weight 1.6358) and DRG 552 (Medical Back Problems without MCC, relative weight 0.9584), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
