About D04.111

D04.111 is the ICD-10-CM diagnosis code for carcinoma in situ of skin of right upper eyelid, including canthus. 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 D04.11 (carcinoma in situ of skin of right eyelid, including canthus), D04.111 is specifically for carcinoma in situ of skin of right upper eyelid, including canthus. Related codes cover lower eyelid, including canthus (D04.112).

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 124 (Other Disorders of the Eye with MCC or Thrombolytic Agent, relative weight 1.2471) and DRG 125 (Other Disorders of the Eye without MCC, relative weight 0.7702), in MDC 02 (Diseases and Disorders of the Eye), 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 was added in FY2019, effective October 1, 2018.
