D22.5Melanocytic nevi of trunk

D22.5 is the ICD-10-CM diagnosis code for Melanocytic nevi of trunk. It belongs to category D22 (Melanocytic nevi), block D10-D36 (benign neoplasms, except benign neuroendocrine tumors) and chapter 2 (neoplasms). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within D22 (Melanocytic nevi), D22.5 is specifically for Melanocytic nevi of trunk. Related codes cover 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 upper limb, including shoulder (D22.6), of lower limb, including hip (D22.7) and unspecified (D22.9).

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 216.5 (benign neoplasm of skin of trunk, except scrotum).
