I87.331Chronic venous hypertension (idiopathic) with ulcer and inflammation of right lower extremity

I87.331 is the ICD-10-CM diagnosis code for chronic venous hypertension (idiopathic) with ulcer and inflammation of right lower extremity. It belongs to category I87 (other disorders of veins), 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 I87.33 (chronic venous hypertension (idiopathic) with ulcer and inflammation), I87.331 is specifically for chronic venous hypertension (idiopathic) with ulcer and inflammation of right lower extremity. Related codes cover of left lower extremity (I87.332), of bilateral lower extremity (I87.333) and of unspecified lower extremity (I87.339).

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 299 (Peripheral Vascular Disorders with MCC, relative weight 1.5842), DRG 300 (Peripheral Vascular Disorders with CC, relative weight 1.0464) and DRG 301 (Peripheral Vascular Disorders without CC/MCC, relative weight 0.7133), in MDC 05 (Diseases and Disorders of the Circulatory 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 459.33 (chronic venous hypertension with ulcer and inflammation).
