About D23.9
D23.9 is the ICD-10-CM diagnosis code for other benign neoplasm of skin, unspecified. It belongs to category D23 (other benign neoplasms of skin), 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 D23, choose D23.9 (skin, unspecified) only when documentation doesn't support a more specific option: skin of lip (D23.0), skin of eyelid, including canthus (D23.1), skin of ear and external auricular canal (D23.2), skin of other and unspecified parts of face (D23.3), skin of scalp and neck (D23.4), skin of trunk (D23.5), skin of upper limb, including shoulder (D23.6) and skin of lower limb, including hip (D23.7).
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.
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 216.9 (benign neoplasm of skin, site unspecified).
