What CMS assigns to L98
120 of the 145 codes group to Wound (116) and MMTA - Other (4); 25 are assigned no clinical group. Comorbidity subgroups: 120 toward Non-Pressure Chronic Ulcers; 1 toward Cutaneous Abscess, Cellulitis, and Lymphangitis; 24 are assigned none. 120 of the 145 can lead a claim.
- Non-Pressure Chronic Ulcers
- Cutaneous Abscess, Cellulitis, and Lymphangitis: can award the low comorbidity tier as a secondary diagnosis.
