ICD-10 code for Poikiloderma

The ICD-10-CM code for Poikiloderma is L81.6 (Other disorders of diminished melanin formation). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on L81.6.

Within L81, choose L81.6 (Other disorders of diminished melanin formation) only when documentation doesn't support a more specific option: postinflammatory hyperpigmentation (L81.0), Chloasma (L81.1), Freckles (L81.2), cafe au lait spots (L81.3), other melanin hyperpigmentation (L81.4), Leukoderma, not elsewhere classified (L81.5), pigmented purpuric dermatosis (L81.7), other specified disorders of pigmentation (L81.8) and 1 more.

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), DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772) and DRG 795 (Normal Newborn, relative weight 0.2022), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
