About R23.8

R23.8 is the ICD-10-CM diagnosis code for other skin changes. It belongs to category R23 (other skin changes), block R20-R23 (symptoms and signs involving the skin and subcutaneous tissue) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within R23, choose R23.8 (Other skin changes) only when documentation doesn't support a more specific option: Cyanosis (R23.0), Pallor (R23.1), Flushing (R23.2), spontaneous ecchymoses (R23.3), changes in skin texture (R23.4) and unspecified skin changes (R23.9).

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 782.9 (other symptoms involving skin and integumentary tissues).
