ICD-10 Code H35.043 – Retinal micro-aneurysms, unspecified, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.043 – Retinal micro-aneurysms, unspecified, bilateral
What it is
H35.043 identifies micro-aneurysms in both retinas when the record does not specify a cause or further detail. Use it for bilateral retinal capillary outpouchings documented on eye examination or imaging.
Clinical signs
Findings may include small retinal vascular dilations seen on dilated fundus exam, often with associated retinal hemorrhages or exudative changes. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents bilateral retinal micro-aneurysms and does not name a more specific retinal disorder. It also fits when the note confirms the finding but leaves the etiology unspecified. If the record identifies an underlying disease, code that condition as well, when instructed.
Do not use for
Do not use H35.043 for unilateral micro-aneurysms or when the chart specifies a different retinal diagnosis. Do not use it if the documentation is too vague; check documentation.
Coding tip
Confirm both laterality and whether the provider documented an unspecified retinal finding before assigning H35.043.
