About L85.8

L85.8 is the ICD-10-CM diagnosis code for other specified epidermal thickening. It belongs to category L85 (other epidermal thickening), block L80-L99 (other disorders of the skin and subcutaneous tissue) and chapter 12 (diseases of the skin and subcutaneous tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within L85, choose L85.8 (Other specified epidermal thickening) only when documentation doesn't support a more specific option: acquired ichthyosis (L85.0), acquired keratosis [keratoderma] palmaris et plantaris (L85.1), keratosis punctata (palmaris et plantaris) (L85.2), xerosis cutis (L85.3) and epidermal thickening, unspecified (L85.9).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 606 (Minor Skin Disorders with MCC, relative weight 1.5728) and DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 701.8 (other specified hypertrophic and atrophic conditions of skin).
