About coding acquired keratoderma
The ICD-10-CM code for acquired keratoderma is L85.1 (Acquired keratosis [keratoderma] palmaris et plantaris). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on L85.1.
Within L85 (other epidermal thickening), L85.1 is specifically for acquired keratosis [keratoderma] palmaris et plantaris. Related codes cover acquired ichthyosis (L85.0), keratosis punctata (palmaris et plantaris) (L85.2), xerosis cutis (L85.3), other specified epidermal thickening (L85.8) and epidermal thickening, unspecified (L85.9).
Don't report L85.1 together with the conditions in its Excludes1 note: inherited keratosis palmaris et plantaris (Q82.8).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
