ICD-10 code for skin nevus
From the official ICD-10-CM alphabetic index entry “Nevus › skin”. Page updated September 29, 2026.
About coding skin nevus
The ICD-10-CM code for skin nevus is D22.9 (Melanocytic nevi, unspecified). The official index lists 72 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on D22.9.
Within D22, choose D22.9 (unspecified) only when documentation doesn't support a more specific option: of lip (D22.0), of eyelid, including canthus (D22.1), of ear and external auricular canal (D22.2), of other and unspecified parts of face (D22.3), of scalp and neck (D22.4), of trunk (D22.5), of upper limb, including shoulder (D22.6) and of lower limb, including hip (D22.7).
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.
