About coding spinal stenosis
The ICD-10-CM code for spinal stenosis is M48.00 (Spinal stenosis, site unspecified). The official index lists 9 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M48.00.
Within M48.0, choose M48.00 (site unspecified) only when documentation doesn't support a more specific option: occipito-atlanto-axial region (M48.01), cervical region (M48.02), cervicothoracic region (M48.03), thoracic region (M48.04), thoracolumbar region (M48.05), lumbar region (M48.06), lumbosacral region (M48.07) and sacral and sacrococcygeal region (M48.08).
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.
