What CMS assigns to L89
108 of the 175 codes group to Wound (107) and MMTA - Other (1); 67 are assigned no clinical group. 93 of the 175 count toward the Stages Two through Four and Unstageable pressure ulcers by site comorbidity subgroup; 82 are assigned none. 108 of the 175 can lead a claim. CMS attaches a code-first note to all 175.
- Stages Two through Four and Unstageable pressure ulcers by site: can award the low comorbidity tier as a secondary diagnosis.
Code first
CMS grouper convention 110, on all 175 codes. Code first:
- any associated gangrene (I96)
