ICD-10 Code D31.31 – Benign neoplasm of right choroid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D31.31 – Benign neoplasm of right choroid
What it is
D31.31 identifies a benign, noncancerous tumor of the choroid in the right eye. It is used when documentation clearly states the lesion is benign and located in the right choroid.
Clinical signs
Clinical features vary; refer to documentation. Eye findings may be incidental on exam or imaging, and the record should support a right choroidal mass or lesion with benign behavior.
When to use this code
Use D31.31 when the provider documents a benign neoplasm of the right choroid, such as on ophthalmology evaluation or imaging review. You should code it when the laterality and benign nature are both stated. If the note only says “choroidal lesion,” check documentation before assigning the code.
Do not use for
Do not use this code for malignant choroidal tumors, unspecified laterality, or lesions in the left eye. If the behavior or eye side is unclear, check documentation.
Coding tip
Confirm both “benign” and “right choroid” in the record before coding, because laterality and lesion type drive correct code selection.
