What This Code Means
M48.00 is the ICD-10-CM diagnosis code for spinal stenosis, site unspecified. Narrowing of the spinal canal (the space where the spinal cord runs) at an unspecified location in the spine. M48.00 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering spondylopathies (m45-m49).
M48.00 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28, V24, ESRD, or RxHCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
This is a non-specific code; always attempt to identify the anatomical region (cervical, thoracic, lumbar, etc.) for more precise coding.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for M48.00 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This is a non-specific code; always attempt to identify the anatomical region (cervical, thoracic, lumbar, etc.) for more precise coding
- •Spinal stenosis may present with pain, numbness, or weakness depending on severity and location
