Diabetic Retinopathy Secondary to Diabetes: VA Claim Guide

Overview

Diabetic retinopathy is damage to the blood vessels of the retina caused by diabetes. Untreated, it can progress to serious vision loss. For veterans with service-connected diabetes, it is one of the most medically straightforward secondary conditions, because the diagnosis itself names diabetes as the cause.

What varies is the rating. VA rates retinopathy under Diagnostic Code 6040 on either visual impairment or the number of treatment visits in the past year, whichever gives the higher rating. Under Note (1) to the diabetes code (DC 7913), a compensable complication is rated separately from diabetes, while a noncompensable one is considered part of the diabetes rating. So the practical questions are what your eye exams show and how often you are treated.

How Retinopathy Is Connected to Diabetes

Diabetic retinopathy is caused by diabetes. Over time, high blood glucose damages the small blood vessels of the retina, the light-sensing tissue at the back of the eye. The National Eye Institute (NEI) calls diabetic retinopathy the most common cause of vision loss for people with diabetes.

Stages. In non-proliferative diabetic retinopathy (NPDR), damaged vessels bulge (microaneurysms), leak, and close off. In proliferative diabetic retinopathy (PDR), the retina grows fragile new vessels that can bleed into the eye or pull on the retina and detach it.

Diabetic macular edema (DME). Leaking vessels can cause fluid to build up in the macula, which blurs central vision. NEI reports that over time about 1 in 15 people with diabetes will develop DME. DME and PDR are usually treated with intravitreal anti-VEGF injections or laser. Those treatment visits matter for VA ratings, as explained below.

Glucose control changes the risk. In the Diabetes Control and Complications Trial (DCCT, New England Journal of Medicine, 1993), intensive glucose control in type 1 diabetes reduced the risk of developing retinopathy by 76% and slowed progression of existing retinopathy by 54% compared with conventional therapy. That is direct evidence that the retinal damage is driven by diabetes.

Retinopathy should not be confused with other eye conditions that can accompany diabetes, such as cataracts or glaucoma. These are separate diagnoses, rated separately, and each needs its own link to diabetes.

Evidence Requirements

To claim diabetic retinopathy secondary to diabetes, you need:

• Current retinopathy diagnosis: A diagnosis from an ophthalmologist or optometrist based on a comprehensive dilated eye examination. The diagnosis should specify the type and stage — non-proliferative diabetic retinopathy (mild, moderate, or severe), proliferative diabetic retinopathy, or diabetic macular edema.
• Service-connected diabetes documentation: Your VA rating decision letter confirming diabetes mellitus is service-connected.
• Medical statement: A diagnosis of “diabetic retinopathy” already attributes the condition to diabetes. A brief statement from your eye doctor confirming the diagnosis and that it is a complication of your diabetes is usually enough. A longer opinion is needed only if another cause of retinal disease, such as hypertensive retinopathy or retinal vein occlusion, is in the record.
• Eye examination records: Documentation of dilated eye exams, including fundoscopy findings, optical coherence tomography (OCT) results, fluorescein angiography (if performed), and visual acuity measurements.
• Visual acuity records: Documented best-corrected visual acuity for each eye. If visual acuity is impaired, these measurements directly determine your rating.
• Visual field testing (if applicable): If retinopathy has affected your peripheral vision, visual field testing (Goldmann or automated perimetry) documents the extent of field loss.
• Diabetes treatment records: Documentation showing your diabetes history, A1C levels, treatment regimen, and how well blood sugar has been controlled. These records support the connection between your diabetes and retinopathy.
• Lay statements: Personal descriptions of how vision changes affect your daily life — difficulty reading, driving at night, recognizing faces, performing work tasks, and any falls or accidents related to impaired vision.

Nexus Letter Tips

The diabetes-retinopathy link is not disputed, so the statement can be short:

Who should write it: The ophthalmologist or optometrist who manages your diabetic eye disease.

Essential content: The letter should state that your diabetic retinopathy is “at least as likely as not” caused by your service-connected diabetes mellitus. Include:

1. The provider’s credentials and relevant ophthalmic expertise
2. Confirmation of a clinical examination and review of medical records
3. Your specific retinopathy diagnosis with staging
4. Current visual acuity measurements and any visual field findings
5. A statement that the retinopathy is a microvascular complication of your diabetes
6. The dates and types of treatment visits (injections, laser, surgery) in the past 12 months, since these can set the rating
7. The “at least as likely as not” standard

Simplicity advantage: The statement does not need to argue that diabetes can cause retinopathy. It only needs to confirm that your retinopathy is diabetic and document its current severity.

Rating Criteria for Diabetic Retinopathy

Diabetic retinopathy is rated under Diagnostic Code 6040 using the General Rating Formula for Diseases of the Eye, which evaluates the condition “on the basis of either visual impairment due to the particular condition or on incapacitating episodes, whichever results in a higher evaluation.” The current schedule has no separate 10% rating for “active pathology” alone; without visual impairment or documented treatment visits, retinopathy may be rated 0%.

Based on visual acuity impairment (DC 6061-6066):

• Ratings from 10% to 100% based on corrected visual acuity in each eye. For example, 20/50 in one eye with 20/40 in the other is rated 10%. 20/200 in one eye with 20/40 in the other is rated 20%. Complete blindness in both eyes is rated 100%.

Based on visual field loss (DC 6080):

• 10% to 100% based on the extent of visual field contraction. A remaining field of 46 to 60 degrees in both eyes is rated 10%; 31 to 45 degrees, 30%; 16 to 30 degrees, 50%; 6 to 15 degrees, 70%; and 5 degrees in both eyes, 100%.

Based on incapacitating episodes:

• An incapacitating episode is “an eye condition severe enough to require a clinic visit to a provider specifically for treatment purposes,” such as intravitreal injections or laser treatment. Ratings are based on documented treatment visits in the past 12 months: at least 1 but less than 3 visits, 10%; at least 3 but less than 5, 20%; at least 5 but less than 7, 40%; 7 or more, 60%.

Important note: Treatment visits are often the fastest route to a compensable rating. Anti-VEGF injections are usually given as a series of scheduled visits, and each clinic visit specifically for treatment counts toward the incapacitating-episode levels (Notes 1 and 2 to the General Rating Formula). Keep a list of treatment dates. As retinopathy progresses, you can file for an increase without re-proving the link to diabetes.

C&P Exam Tips

The C&P exam for diabetic retinopathy will be conducted by an ophthalmologist or optometrist and will include a comprehensive eye examination:

• Bring your current glasses or contacts. Visual acuity is measured with best correction. Bring your most current prescription eyewear.
• Bring eye examination records. Copies of recent dilated eye exams, OCT results, and any prior retinopathy documentation ensure the examiner has complete information.
• Report all vision symptoms. Describe blurry vision, floaters, dark spots, difficulty seeing at night, loss of color vision, difficulty reading, and any sudden vision changes. Be specific about which eye is affected and how symptoms impact daily activities.
• Describe functional impact. Explain how vision changes affect your daily life, including driving (especially at night), reading, using a computer, recognizing faces, navigating stairs, and work tasks. The rating itself is set by the measurements and treatment count, but functional detail matters for extraschedular consideration and TDIU.
• List every treatment visit in the past 12 months. Report laser photocoagulation, anti-VEGF injections (such as Avastin, Lucentis, or Eylea), and vitrectomy, with dates. The number of treatment visits directly sets the incapacitating-episode rating.
• Discuss diabetes management. The examiner may ask about your diabetes control. Be honest about your A1C levels and treatment adherence. Poorly controlled diabetes supports the connection to retinopathy, though well-controlled diabetes does not disqualify you — retinopathy can develop even with good control.
• Report both eyes separately. Retinopathy may affect your eyes differently. Describe symptoms and limitations for each eye individually.
• Do not wear dark glasses inside. Unless you have a medical need, wearing dark glasses during the exam may prevent the examiner from fully assessing your condition.

Impact on Combined Rating

Adding a retinopathy rating to your existing diabetes rating increases your combined VA disability:

Example scenario: A veteran has a 20% diabetes rating and receives 10% for retinopathy.

1. 20% combined with 10% = 28
2. 28 rounds to 30%

Example with multiple diabetes complications: A veteran has 20% diabetes, 10% retinopathy, 10% hypertension, and 10% peripheral neuropathy in each leg.

1. Legs first (bilateral factor, 38 CFR 4.26): 10% combined with 10% = 19. Add 10% of 19 (1.9) = 20.9, treated as 21
2. 21 combined with 20% diabetes = 37
3. 37 combined with 10% retinopathy = 43
4. 43 combined with 10% hypertension = 49
5. 49 rounds to 50%

Progressive nature: Retinopathy can worsen over time. If you start needing more frequent injections or laser treatment, or your corrected vision drops, file for an increase with the new treatment dates and acuity measurements. Use our VA disability calculator to check combinations.
