About coding Keloma
The ICD-10-CM code for Keloma is L91.0 (Hypertrophic scar).
Within L91 (hypertrophic disorders of skin), L91.0 is specifically for hypertrophic scar. Related codes cover other hypertrophic disorders of the skin (L91.8) and hypertrophic disorder of the skin, unspecified (L91.9).
The conditions in its Excludes2 note aren't part of L91.0, but may be coded alongside it if the patient has both: acne keloid (L73.0) and scar NOS (L90.5).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
