ICD-10 Code D19.0 – Benign neoplasm of mesothelial tissue of pleura (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D19.0 – Benign neoplasm of mesothelial tissue of pleura
What it is
D19.0 identifies a noncancerous growth arising from mesothelial tissue of the pleura, the membrane lining the chest cavity and covering the lungs. Use it when documentation clearly states a benign pleural mesothelial neoplasm.
Clinical signs
Clinical features vary; refer to documentation. Pleural lesions may be found incidentally on imaging or during evaluation of chest symptoms, but the record should confirm a benign mesothelial tumor.
When to use this code
Use D19.0 when the provider documents a benign neoplasm of the pleura, such as a benign mesothelial tumor, and the site is pleural. It is appropriate for confirmed pathology, imaging-supported diagnosis, or specialist assessment that names this condition. Check documentation if the laterality, behavior, or exact tissue type is unclear.
Do not use for
Do not use this code for malignant pleural tumors, metastatic disease, or nonspecific pleural thickening. If the lesion is not documented as benign mesothelial tissue, check documentation.
Coding tip
Code only when the record specifies benign mesothelial pleural neoplasm; otherwise query for the exact pleural diagnosis.
