ICD-10 Code D15.7 – Benign neoplasm of other specified intrathoracic organs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D15.7 – Benign neoplasm of other specified intrathoracic organs
What it is
D15.7 identifies a noncancerous tumor in an intrathoracic organ not named by a more specific code. Use it when documentation states a benign neoplasm within the chest and the exact organ is specified.
Clinical signs
Clinical features vary; refer to documentation. These lesions may be found incidentally on imaging or during evaluation of chest symptoms, but coding depends on the recorded diagnosis, not on presumed symptoms.
When to use this code
Use D15.7 when the provider documents a benign neoplasm involving an intrathoracic organ such as a structure in the thorax that is not separately indexed elsewhere. It is appropriate when the record clearly supports a benign tumor and no more specific code exists. If the site is uncertain, check documentation before assigning the code.
Do not use for
Do not use this code for malignant neoplasms, metastatic disease, or unspecified chest masses without a documented benign neoplasm. If the lesion is in a more specific organ or category, choose the more precise code.
Coding tip
Verify the exact intrathoracic organ and the word “benign” in the provider note before coding D15.7.
