What CMS assigns to J41
All 3 codes group to MMTA - Respiratory. 2 of the 3 count toward the Bronchitis, Emphysema, and Interstitial Lung Disease comorbidity subgroup; 1 is assigned none. Every code can lead a claim.
- Bronchitis, Emphysema, and Interstitial Lung Disease: counts toward the high comorbidity tier only in an interaction pair.
