E08.3551 is a billable ICD-10-CM diagnosis code for diabetes mellitus due to underlying condition with stable proliferative diabetic retinopathy, right eye. The 7th character 1 means right eye. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 8, 10, 19, 124 through 125. The code is a manifestation code that cannot be reported as the principal diagnosis. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Diabetes mellitus with complication; Diabetes mellitus, due to underlying condition, drug or chemical induced, or other specified type; and Retinal and vitreous conditions.

For Medicare Advantage risk adjustment, E08.3551 maps to CMS-HCC Category 37 (Diabetes with Chronic Complications) under the V28 model, adding a risk factor of about 0.166 for a community, non-dual, aged beneficiary in payment year 2027.

Manifestation codes describe the manifestation of an underlying disease, not the disease itself, and therefore should not be used as a principal diagnosis.

Medicare Risk Adjustment (HCC)Billing

Coding GuidelinesGuidance

The diabetes mellitus codes are combination codes that include the type of diabetes mellitus, the body system affected, and the complications affecting that body system. As many codes within a particular category as are necessary to describe all of the complications of the disease may be used. They should be sequenced based on the reason for a particular encounter. Assign as many codes from categories E08 - E13 as needed to identify all of the associated conditions that the patient has.

Patient EducationClinical

Diabetes

Diabetes, also known as diabetes mellitus, is a disease in which your blood glucose, or blood sugar, levels are too high. Glucose is your body's main source of energy. Your body can make glucose, but it also comes from the food you eat. Insulin is a hormone made by your pancreas.

Questions About E08.3551Overview

Is E08.3551 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report diabetes mellitus due to underlying condition with stable proliferative diabetic retinopathy, right eye on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character 1 in E08.3551 mean?

The final character 1 means right eye, in this case for the diabetes mellitus due to underlying condition with stable proliferative diabetic retinopathy. It comes from the 7th character list in the CMS Tabular List for this category.

What MS-DRG does E08.3551 group to?

On inpatient claims, diabetes mellitus due to underlying condition with stable proliferative diabetic retinopathy, right eye maps to MS-DRG 125, 8, 10, 19, 124, with relative weights from 0.7699 to 7.5461 depending on complications. Higher weights mean higher Medicare reimbursement.

Can E08.3551 be a principal diagnosis?

No. This is a manifestation code: diabetes mellitus due to underlying condition with stable proliferative diabetic retinopathy, right eye describes the manifestation of an underlying disease rather than the disease itself, so the underlying condition is sequenced first.

Can E08.3551 be reported with a code from E09?

Not as a rule. The Excludes1 note at E08, which applies to E08.3551, lists "drug or chemical induced diabetes mellitus (E09.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

What HCC is E08.3551?

E08.3551 (diabetes mellitus due to underlying condition with stable proliferative diabetic retinopathy, right eye) maps to CMS-HCC Category 37 (Diabetes with Chronic Complications), commonly written as HCC 37, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 18 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. In the Part D prescription drug model it maps to RxHCC 30.

Does E08.3551 risk-adjust for Medicare Advantage payment?

Yes. When documented and reported on a Medicare Advantage encounter, E08.3551 adds a risk adjustment factor of about 0.166 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.166 to 0.280 depending on the payment segment). A more severe related category (HCC 35 and HCC 36) supersedes it when both are reported. See the full factor table on the HCC 37 category page.
