CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

I85.00 is a billable ICD-10-CM diagnosis code for esophageal varices without bleeding. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 368 through 370. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 61 closely related codes. Coders also document this condition as dilatation of stomach. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Other specified diseases of veins and lymphatics.

For Medicare Advantage risk adjustment, I85.00 maps to CMS-HCC Category 63 (Chronic Liver Failure/End-Stage Liver Disorders) under the V28 model, adding a risk factor of about 0.962 for a community, non-dual, aged beneficiary in payment year 2027.

When esophageal varices without bleeding is the principal diagnosis on an inpatient stay, it groups to MS-DRG 369, 370, 368, with relative weights from 0.6741 to 1.6434 depending on complications. Higher weights mean higher Medicare reimbursement.

Is I85.00 a CC or MCC?

CMS lists I85.00 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 61 closely related codes in its exclusion list.

Does I85.00 need an additional code?

What HCC is I85.00?

I85.00 (esophageal varices without bleeding) maps to CMS-HCC Category 63 (Chronic Liver Failure/End-Stage Liver Disorders), commonly written as HCC 63, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 27 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. It does not map to any RxHCC in the Part D prescription drug model.

Does I85.00 risk-adjust for Medicare Advantage payment?

Yes. When documented and reported on a Medicare Advantage encounter, I85.00 adds a risk adjustment factor of about 0.962 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.861 to 1.209 depending on the payment segment). A more severe related category (HCC 62) supersedes it when both are reported. See the full factor table on the HCC 63 category page.
