About D12.0

D12.0 is the ICD-10-CM diagnosis code for benign neoplasm of cecum. It belongs to category D12 (benign neoplasm of colon, rectum, anus and anal canal), 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 D12 (benign neoplasm of colon, rectum, anus and anal canal), D12.0 is specifically for benign neoplasm of cecum. Related codes cover appendix (D12.1), ascending colon (D12.2), transverse colon (D12.3), descending colon (D12.4), sigmoid colon (D12.5), colon, unspecified (D12.6), rectosigmoid junction (D12.7), rectum (D12.8) and 1 more.

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 393 (Other Digestive System Diagnoses with MCC, relative weight 1.5881), DRG 394 (Other Digestive System Diagnoses with CC, relative weight 0.9228) and DRG 395 (Other Digestive System Diagnoses without CC/MCC, relative weight 0.6382), 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 211.3 (benign neoplasm of colon).
