About I85.00

I85.00 is the ICD-10-CM diagnosis code for esophageal varices without bleeding. It belongs to category I85 (esophageal varices), block I80-I89 (diseases of veins, lymphatic vessels and lymph nodes, not elsewhere classified) and chapter 9 (diseases of the circulatory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within I85.0, choose I85.00 (without bleeding) only when documentation doesn't support a more specific option: with bleeding (I85.01).

Use an additional code to identify: alcohol abuse and dependence (F10.-).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 368 (Major Esophageal Disorders with MCC, relative weight 1.6433), DRG 369 (Major Esophageal Disorders with CC, relative weight 0.9922) and DRG 370 (Major Esophageal Disorders without CC/MCC, relative weight 0.6744), in MDC 06 (Diseases and Disorders of the Digestive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 456.1 (esophageal varices without mention of bleeding).
