ICD-10 Code D31.30 – Benign neoplasm of unspecified choroid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D31.30 – Benign neoplasm of unspecified choroid
What it is
This code identifies a noncancerous growth in the choroid, the vascular layer beneath the retina. Use it when the record says the choroid is involved but does not specify a more precise site.
Clinical signs
Findings may include an incidental choroidal mass on eye examination or imaging. Clinical features vary; refer to documentation for lesion size, location, and whether the diagnosis was confirmed by ophthalmic evaluation.
When to use this code
Use D31.30 when the provider documents a benign neoplasm of the choroid without naming right or left eye, or a more specific choroidal site. It also fits when the note confirms a benign choroidal lesion and laterality is not stated. Check documentation if the lesion is described only as suspicious, monitored, or undetermined.
Do not use for
Do not use this code for malignant tumors, metastatic lesions, or nonspecific retinal or uveal masses. If the documentation identifies a different eye structure or a more specific choroidal location, code that instead.
Coding tip
Look for laterality and exact anatomic wording in the ophthalmology note before assigning the unspecified code.
