About D04.30
D04.30 is the ICD-10-CM diagnosis code for carcinoma in situ of skin of unspecified part of face. It belongs to category D04 (carcinoma in situ of skin), block D00-D09 (in situ neoplasms) 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 D04.3, choose D04.30 (unspecified part of face) only when documentation doesn't support a more specific option: other parts of face (D04.39).
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 232.3 (carcinoma in situ of skin of other and unspecified parts of face).
