- Billable — Valid for Submission
- Risk Adjusts — HCC 37
- Chronic Condition
E13.29 is a billable ICD-10-CM diagnosis code for other specified diabetes mellitus with other diabetic kidney complication. 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, 698 through 700. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Diabetes mellitus with complication; and Diabetes mellitus, due to underlying condition, drug or chemical induced, or other specified type.
For Medicare Advantage risk adjustment, E13.29 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.

Medicare Risk Adjustment (HCC)Billing
E13.29 maps to a payment category in the CMS-HCC model used to risk-adjust Medicare Advantage payments. Weights are the published community factors for payment year 2027.

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.

Notes
General instructions on how these codes are used.
- All neoplasms, whether functionally active or not, are classified in Chapter 2. Appropriate codes in this chapter (i.e. E05.8, E07.0, E16-E31, E34.-) may be used as additional codes to indicate either functional activity by neoplasms and ectopic endocrine tissue or hyperfunction and hypofunction of endocrine glands associated with neoplasms and other conditions classified elsewhere.

Questions About E13.29Overview
Is E13.29 (Other specified diabetes mellitus with kidney complications) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other specified diabetes mellitus with other diabetic kidney complication on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does E13.29 group to?
When other specified diabetes mellitus with other diabetic kidney complication is the principal diagnosis on an inpatient stay, it groups to MS-DRG 8, 699, 698, 10, 19, 700, with relative weights from 0.6740 to 7.5461 depending on complications. Higher weights mean higher Medicare reimbursement.
Can E13.29 be reported with a code from E10?
Not as a rule. The Excludes1 note at E13, which applies to E13.29, lists "diabetes (mellitus) due to autoimmune process (E10.-)". 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 E13.29 need an additional code?
When the condition applies, yes. The Use Additional Code note at E13, which applies to E13.29, reads: code to identify control using: injectable non-insulin antidiabetic drugs (Z79.85); insulin (Z79.4); oral antidiabetic drugs (Z79.84); oral hypoglycemic drugs (Z79.84). The additional code is reported after E13.29.
What is the ICD-9 equivalent of E13.29?
Under the General Equivalence Mappings, other specified diabetes mellitus with other diabetic kidney complication converts to ICD-9-CM 249.40 (sec DM renl nt st uncntr) and 250.40 (DMII renl nt st uncntrld). The mapping is approximate, so confirm the match fits the documentation.
What HCC is E13.29?
E13.29 (other specified diabetes mellitus with other diabetic kidney complication) 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 E13.29 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, E13.29 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.
