About coding acquired ichthyosis
The ICD-10-CM code for acquired ichthyosis is L85.0 (Acquired ichthyosis).
Within L85 (other epidermal thickening), L85.0 is specifically for acquired ichthyosis. Related codes cover acquired keratosis [keratoderma] palmaris et plantaris (L85.1), 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 L85.0 together with the conditions in its Excludes1 note: congenital ichthyosis (Q80.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for L85.0)
- congenital ichthyosis (Q80.-)
