About D01.7

D01.7 is the ICD-10-CM diagnosis code for carcinoma in situ of other specified digestive organs. It belongs to category D01 (carcinoma in situ of other and unspecified digestive organs), 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 D01, choose D01.7 (other specified digestive organs) only when documentation doesn't support a more specific option: colon (D01.0), rectosigmoid junction (D01.1), rectum (D01.2), anus and anal canal (D01.3), other and unspecified parts of intestine (D01.4), liver, gallbladder and bile ducts (D01.5) and digestive organ, unspecified (D01.9).

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 374 (Digestive Malignancy with MCC, relative weight 2.1109), DRG 375 (Digestive Malignancy with CC, relative weight 1.1838) and DRG 376 (Digestive Malignancy without CC/MCC, relative weight 0.8929), in MDC 06 (Diseases and Disorders of the Digestive System), 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 230.9 (carcinoma in situ of other and unspecified digestive organs).
