What CMS assigns to M48
107 of the 119 codes group to Musculoskeletal Rehabilitation; 12 are assigned no clinical group. 2 of the 119 count toward the Lumbar Spinal Stenosis comorbidity subgroup; 117 are assigned none. 107 of the 119 can lead a claim.
- Lumbar Spinal Stenosis: counts toward the high comorbidity tier only in an interaction pair.
