About I82.3

I82.3 is the ICD-10-CM diagnosis code for embolism and thrombosis of renal vein. It belongs to category I82 (other venous embolism and thrombosis), 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 I82 (other venous embolism and thrombosis), I82.3 is specifically for embolism and thrombosis of renal vein. Related codes cover Budd-Chiari syndrome (I82.0), thrombophlebitis migrans (I82.1), embolism and thrombosis of vena cava and other thoracic veins (I82.2), acute embolism and thrombosis of deep veins of lower extremity (I82.4), chronic embolism and thrombosis of deep veins of lower extremity (I82.5), acute embolism and thrombosis of veins of upper extremity (I82.6), chronic embolism and thrombosis of veins of upper extremity (I82.7), embolism and thrombosis of other specified veins (I82.8) and 4 more.

Code first venous embolism and thrombosis complicating: abortion, ectopic or molar pregnancy (O00-O07, O08.7) and pregnancy, childbirth and the puerperium (O22.-, O87.-).

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 698 (Other Kidney and Urinary Tract Diagnoses with MCC, relative weight 1.6398), DRG 699 (Other Kidney and Urinary Tract Diagnoses with CC, relative weight 1.0003) and DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), 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 453.3 (other venous embolism and thrombosis of renal vein).
