ICD-10 Code D35.7 – Benign neoplasm of other specified endocrine glands (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D35.7 – Benign neoplasm of other specified endocrine glands
What it is
This code identifies a noncancerous tumor arising in an endocrine gland not named in a more specific ICD-10 category. Use it when the record clearly states a benign neoplasm of an endocrine gland and no more specific site is documented.
Clinical signs
Clinical features vary; refer to documentation. These tumors may be found incidentally or because of local mass effects or hormone-related findings, depending on the gland involved and whether the lesion is functioning.
When to use this code
Use D35.7 when the provider documents a benign neoplasm in an endocrine gland that is not covered by a more specific code. It may also fit when the note identifies the lesion as benign but does not name a more exact endocrine site. If the documentation is vague, check documentation before assigning the code.
Do not use for
Do not use this code for malignant neoplasms, uncertain behavior, or endocrine tumors with a more specific site code. Do not use it when the record only says “mass” or “lesion” without confirming a benign neoplasm.
Coding tip
Confirm the exact endocrine gland and benign nature in the provider note before coding; if the site is specified elsewhere, choose the more precise code.
