ICD-10 Code D49.81 – Neoplasm of unspecified behavior of retina and choroid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D49.81 – Neoplasm of unspecified behavior of retina and choroid
What it is
This code identifies a retinal or choroidal mass whose behavior is not clearly documented as benign or malignant. Use it when the record describes an unspecified neoplasm involving these eye structures.
Clinical signs
Clinical features vary; refer to documentation. Findings may include an ocular lesion seen on exam or imaging, but the chart should support that the growth is in the retina or choroid and not better classified elsewhere.
When to use this code
Use D49.81 when the clinician documents a neoplasm of the retina or choroid and does not state whether it is benign, malignant, or in situ. It is also appropriate when pathology or specialist notes describe uncertain behavior and no more specific code is available. Check documentation if the site or behavior is unclear.
Do not use for
Do not use this code for clearly benign or malignant eye tumors, or for lesions in other ocular structures. If the note identifies a different diagnosis, code that condition instead.
Coding tip
Verify both the anatomic site and the tumor behavior before assigning D49.81.
