What is ICD-10 code E09.59?

E09.59 is the ICD-10-CM diagnosis code for Drug or chemical induced diabetes mellitus with other circulatory complications. Diabetes caused by medications or chemicals with blood vessel or circulation problems not specified in other categories. It belongs to the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89). E09.59 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. E09.59 is part of the FY2026 ICD-10-CM code set published by the CMS National Center for Health Statistics and used on Medicare, Medicaid, and commercial claims in the United States.

Yes. E09.59 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. E09.59 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

Which HCC does E09.59 map to under V28?

E09.59 has no payable CMS-HCC V28 mapping in the final FY2026 CMS file.

What RAF reference is published for E09.59?

E09.59 has no V28 reference coefficient because the final FY2026 source verifies no payable V28 mapping.

What is the V28 vs V24 difference for E09.59?

E09.59 has verified no payable V28 mapping in the final FY2026 source. Select a historical effective period before making any V24 comparison.

What documentation supports E09.59?

Use this code for circulatory complications like diabetic angiopathy variants not captured in E09.51-E09.52 Document the specific circulatory complication clearly E09.59 is not a CMS-HCC V28 payment code in the verified current source, so MEAT is not the payment hook. Documentation still has to support the diagnosis if you report it.

Buddy Documentation Tip

HCC Buddy guidance

The causative drug or chemical must be identified.

The specific circulatory complication must be described in detail, explaining why it does not fit the peripheral angiopathy categories (E09.51-E09.52).

Supporting diagnostic studies (angiography, echocardiography, or vascular imaging) should be documented.

The causal relationship to drug-induced diabetes must be established.

Audit Caution

HCC Buddy guidance

This residual circulatory code should only be used when the vascular complication does not fit peripheral angiopathy codes.

The circulatory complication must be documented as diabetes-related, not just coexisting.

Query the provider if the documentation is unclear about the relationship between diabetes and the vascular finding.

Common Mistakes

HCC Buddy guidance

E09.51 (peripheral angiopathy without gangrene) and E09.52 (with gangrene) are more specific for peripheral vascular disease.

I25.x (chronic ischemic heart disease) or I67.x (cerebrovascular disease) may be coded additionally but should not replace this combination code.

E09.69 (other specified complication) may overlap when the circulatory issue affects multiple systems.

Is E09.59 an HCC code?

E09.59 is not in the CMS-HCC V28 or V24 community payment model. E09.59 has a separate mapping under the CMS-HCC ESRD model (HCC 18 (Diabetes with Chronic Complications)) and the Part D RxHCC model (HCC 30 (Diabetes with Complications)); the applicable result needs member context. E09.59 also appears in the HHS-HCC commercial risk model (HCC 020 (HHS-HCC 020 adult, RAF varies by metal level)), which is a commercial market model rather than a Medicare Advantage payment mapping.

HCC Category Mapping

ESRDHCC 18, Diabetes with Chronic Complications

Not separately weighted

RxHCCHCC 30, Diabetes with Complications

Not separately weighted

These are source-labeled model coefficients, not member totals. A category may still be removed by hierarchy or model cleanup rules. Weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member context, hierarchy and cleanup rules, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains available for historical review.

MEAT review for E09.59

For E09.59, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule.

MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
EEvaluate: test results, medication response, or physical findings reviewed by the provider
AAssess: explicit mention in the assessment or plan with acknowledgment of status
TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis

What This Code Means

E09.59 is the ICD-10-CM diagnosis code for drug or chemical induced diabetes mellitus with other circulatory complications. Diabetes caused by medications or chemicals with blood vessel or circulation problems not specified in other categories. E09.59 sits in the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89), within the section covering diabetes mellitus (e08-e13).

E09.59 has no mapping under the CMS-HCC V28 or V24 community payment models. E09.59 has a separate mapping under the CMS-HCC ESRD model (HCC 18 (Diabetes with Chronic Complications)) and the Part D RxHCC model (HCC 30 (Diabetes with Complications)); the applicable result needs member context. E09.59 also appears in the HHS-HCC commercial risk model (HCC 020 (HHS-HCC 020 adult, RAF varies by metal level)), which is a commercial market model rather than a Medicare Advantage payment mapping. Do not assign V28 risk adjustment value from this page; verify the applicable model and payment year before using this code for risk adjustment.

Use this code for circulatory complications like diabetic angiopathy variants not captured in E09.51-E09.52.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for E09.59 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Use this code for circulatory complications like diabetic angiopathy variants not captured in E09.51-E09.52
•Document the specific circulatory complication clearly

Clinical Significance

Drug or chemical induced diabetes mellitus with other circulatory complications captures vascular manifestations of drug-induced diabetes beyond peripheral angiopathy. This may include diabetic microangiopathy affecting various organ systems, coronary microvascular disease, or cerebrovascular complications attributable to diabetes. These conditions reflect the systemic vascular damage that diabetes causes beyond the commonly coded peripheral arterial disease.

Documentation Requirements

✓The causative drug or chemical must be identified.
✓The specific circulatory complication must be described in detail, explaining why it does not fit the peripheral angiopathy categories (E09.51-E09.52).
✓Supporting diagnostic studies (angiography, echocardiography, or vascular imaging) should be documented.
✓The causal relationship to drug-induced diabetes must be established.

Commonly Confused Codes
