- Billable — Valid for Submission
- Risk Adjusts — HCC 37
- Chronic Condition
E11.22 is a billable ICD-10-CM diagnosis code for type 2 diabetes mellitus with diabetic chronic kidney disease. 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, 673 through 675, 698 through 700. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Chronic kidney disease; Diabetes mellitus with complication; and Diabetes mellitus, Type 2.
For Medicare Advantage risk adjustment, E11.22 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.
This medical diagnosis code is frequently used in Family Practice medical specialties to designate conditions such diabetes mellitus with complications type 2.

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.
If the type of diabetes mellitus is not documented in the medical record the default is E11.-, Type 2 diabetes mellitus.

Clinical InformationClinical
Diabetes Mellitus, Type 2
a subclass of diabetes mellitus that is not insulin-responsive or dependent (niddm). it is characterized initially by insulin resistance and hyperinsulinemia; and eventually by glucose intolerance; hyperglycemia; and overt diabetes. type ii diabetes mellitus is no longer considered a disease exclusively found in adults. patients seldom develop ketosis but often exhibit obesity.
Patient EducationClinical
Diabetes Type 2
Type 2 diabetes is a disease in which your blood glucose, or blood sugar, levels are too high. Glucose is your main source of energy. It comes from the foods you eat. A hormone called insulin helps the glucose get into your cells to give them energy. If you have diabetes, your body doesn't make enough insulin or doesn't use insulin well.

Questions About E11.22Overview
What is the ICD-10 code for type 2 diabetes mellitus with diabetic chronic kidney disease?
The ICD-10-CM code for type 2 diabetes mellitus with diabetic chronic kidney disease is E11.22 (sometimes written as E1122). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is E11.22 (Type 2 diabetes mellitus with kidney complications) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report type 2 diabetes mellitus with diabetic chronic kidney disease on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does E11.22 group to?
When type 2 diabetes mellitus with diabetic chronic kidney disease is the principal diagnosis on an inpatient stay, it groups to MS-DRG 674, 673, 8, 699, 698, 10, 19, 675, 700, with relative weights from 0.6740 to 7.5461 depending on complications. Higher weights mean higher Medicare reimbursement.
Can E11.22 be reported with a code from E08?
Not as a rule. The Excludes1 note at E11, which applies to E11.22, lists "diabetes mellitus due to underlying condition (E08.-)". 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).
Does E11.22 need an additional code?
When the condition applies, yes. The Use Additional Code note reads: code to identify stage of chronic kidney disease (N18.1-N18.6). The additional code is reported after E11.22.
What HCC is E11.22?
E11.22 (type 2 diabetes mellitus with diabetic chronic kidney disease) 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 E11.22 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, E11.22 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.
