Retinal micro-aneurysms, unspecified, unspecified eye

This code signifies the presence of tiny, localized outpouchings or dilations in the retinal blood vessels, specifically micro-aneurysms, without further specification of their location or laterality. These are often an early sign of diabetic retinopathy but can also be associated with other vascular conditions.

Use this code when the physician's documentation confirms the presence of retinal micro-aneurysms but does not specify which eye is affected or provide additional details about their type or cause. This is appropriate when the diagnosis is confirmed but lacks laterality or further specificity.

• Do not use this code if the laterality (right, left, or bilateral) is documented; instead, use the more specific codes for right (H35.041), left (H35.042), or bilateral (H35.043) retinal micro-aneurysms.
• If the underlying cause, such as diabetes, is known, code the underlying systemic condition first, followed by this code.
• Avoid using this code if the documentation specifies other forms of retinal vascular changes, such as hemorrhages or exudates, unless micro-aneurysms are also explicitly noted.
