About D13.7

D13.7 is the ICD-10-CM diagnosis code for benign neoplasm of endocrine pancreas. 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), D13.7 is specifically for benign neoplasm of endocrine pancreas. Related codes cover esophagus (D13.0), stomach (D13.1), duodenum (D13.2), other and unspecified parts of small intestine (D13.3), liver (D13.4), extrahepatic bile ducts (D13.5), pancreas (D13.6) and ill-defined sites within the digestive system (D13.9).

Use an additional code to identify any functional activity..

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 643 (Endocrine Disorders with MCC, relative weight 1.6139), DRG 644 (Endocrine Disorders with CC, relative weight 1.0044) and DRG 645 (Endocrine Disorders without CC/MCC, relative weight 0.7459), in MDC 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders), 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 211.7 (benign neoplasm of islets of Langerhans).
