About D13.1
D13.1 is the ICD-10-CM diagnosis code for benign neoplasm of stomach. It belongs to category D13 (benign neoplasm of other and ill-defined parts of digestive system), 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 D13 (benign neoplasm of other and ill-defined parts of digestive system), D13.1 is specifically for benign neoplasm of stomach. Related codes cover esophagus (D13.0), duodenum (D13.2), other and unspecified parts of small intestine (D13.3), liver (D13.4), extrahepatic bile ducts (D13.5), pancreas (D13.6), endocrine pancreas (D13.7) and ill-defined sites within the digestive system (D13.9).
Don't report D13.1 together with the conditions in its Excludes1 note: benign carcinoid tumor of the stomach (D3A.092).
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 211.1 (benign neoplasm of stomach).
