ICD-10 Code D13.7 – Benign neoplasm of endocrine pancreas (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D13.7 – Benign neoplasm of endocrine pancreas
What it is
D13.7 identifies a noncancerous tumor of the endocrine portion of the pancreas, also called the islets of Langerhans. It means the growth is benign, not malignant, but still requires documentation and follow-up.
Clinical signs
Clinical features vary; refer to documentation. These lesions may be found on imaging, pathology, or during evaluation for a pancreatic mass, and some are noted because of hormone-related symptoms.
When to use this code
Use D13.7 when the provider documents a benign neoplasm arising from the endocrine pancreas. Code it for confirmed benign pancreatic endocrine tumors, including pathology-supported diagnoses. If the record only says pancreatic mass or lesion without a benign endocrine diagnosis, check documentation before assigning this code.
Do not use for
Do not use this code for malignant pancreatic neuroendocrine tumors or unspecified pancreatic neoplasms. If the documentation does not clearly identify the tumor as benign and endocrine, check documentation.
Coding tip
Assign D13.7 only when the record clearly states a benign endocrine pancreatic neoplasm, not just a suspected or nonspecific pancreatic mass.
