What is ICD-10 code E11.29?

E11.29 is the ICD-10-CM diagnosis code for Type 2 diabetes mellitus with other diabetic kidney complication. Type 2 diabetes with other kidney complications besides the main types, such as diabetic glomerulonephritis or other kidney disorders caused by diabetes. E11.29 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. E11.29 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. E11.29 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. E11.29 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.

What is the V28 vs V24 difference for E11.29?

CMS phased in the V28 risk adjustment model over payment years 2024 (33%), 2025 (67%), and 2026 (100%), replacing V24. V28 consolidates HCC categories, removes some lower-acuity conditions, and recalibrates RAF weights across the entire model. For E11.29, V28 maps to Diabetes with Chronic Complications at RAF 0.245 while V24 mapped to Diabetes with Chronic Complications at RAF 0.302. Both models can still appear in legacy data and in payer-specific lookback periods.

What should coders know when reporting E11.29?

Use this code only when the kidney complication is not nephropathy or chronic kidney disease Document the specific kidney complication in the medical record for clarity Because E11.29 maps to a payment HCC, the documentation must also satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's risk adjustment score.

Type 2 diabetes mellitus with other diabetic kidney complication

Type 2 diabetes with other kidney complications besides the main types, such as diabetic glomerulonephritis or other kidney disorders caused by diabetes.

Buddy Insight

Type 2 diabetes mellitus with other diabetic kidney complication captures renal conditions attributable to diabetes that are not classified as nephropathy or chronic kidney disease, such as Kimmelstiel-Wilson disease (nodular diabetic glomerulosclerosis), diabetic papillary necrosis, or other specific renal pathology from diabetes.

Buddy Documentation Tip

HCC Buddy guidance

The medical record must identify the specific renal complication and establish its causal relationship to Type 2 diabetes.

Kidney biopsy results, if obtained, should be documented along with renal function tests and imaging findings.

The provider must confirm the condition does not fit the nephropathy (E11.21) or chronic kidney disease (E11.22) categories.

The provider must confirm the condition does not fit the nephropathy (E11.21) or chronic kidney disease (E11.22) categories.

Audit Caution

HCC Buddy guidance

This residual code should only be used when the kidney complication does not fit E11.21 or E11.22

always consider the more specific codes first. Do not use this code for non-diabetic kidney conditions in diabetic patients. Query the provider when renal documentation is vague to determine the most appropriate code.

Common Mistakes

HCC Buddy guidance

E11.21 (diabetic nephropathy) is the most common diabetic renal code and should be used when nephropathy is documented.

E11.22 (diabetic chronic kidney disease) is for staged CKD attributable to diabetes.

N08 (glomerular disorders in diseases classified elsewhere) may be used as an additional manifestation code alongside this combination code.

Last updated: FY2026 ICD-10-CM Apr update, Apr 1, 2026 through Sep 30, 2026. CMS-HCC V28 is 100% phased in for payment year 2026.

Is E11.29 an HCC code?

Yes. E11.29 maps to Diabetes with Chronic Complications under the CMS-HCC V28 risk adjustment model (and Diabetes with Chronic Complications under V24).

RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.

MEAT Criteria for E11.29

For E11.29to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically, it has to be re-documented and supported each calendar year.

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

Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed E11.29 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

E11.29 is the ICD-10-CM diagnosis code for type 2 diabetes mellitus with other diabetic kidney complication. Type 2 diabetes with other kidney complications besides the main types, such as diabetic glomerulonephritis or other kidney disorders caused by diabetes. E11.29 sits in the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89), within the section covering diabetes mellitus (e08-e13).

Under the CMS-HCC V28 risk adjustment model, E11.29 maps to Diabetes with Chronic Complications (HCC 37) with a community, non-dual, aged base RAF weight of 0.245. Under the older V24 model, E11.29 mapped to the same category but with a base RAF weight of 0.302, V28 recalibrated weights across the entire model. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.

Use this code only when the kidney complication is not nephropathy or chronic kidney disease. Because E11.29 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for E11.29 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
