Clinical InformationClinical

  • Superior Vena Cava Syndrome

    a condition that occurs when the obstruction of the thin-walled superior vena cava interrupts blood flow from the head, upper extremities, and thorax to the right atrium. obstruction can be caused by neoplasms; thrombosis; aneurysm; or external compression. the syndrome is characterized by swelling and/or cyanosis of the face, neck, and upper arms which is called pemberton's sign. classification of svc obstruction is often based on collateral circulation.

  • Venous Stenosis

    a finding indicating narrowing of a vein in one or multiple areas.

  • Subclavian Vein Stenosis

    narrowing of the lumen of the subclavian vein.

  • Inferior Vena Cava Stenosis

    abnormal narrowing of the lumen of the inferior vena cava.

  • Superior Vena Cava Stenosis

    abnormal narrowing of the lumen of the superior vena cava.

Questions About I87.1Overview

Is I87.1 (Other disorders of veins) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report compression of vein on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does I87.1 group to?

When compression of vein is the principal diagnosis on an inpatient stay, it groups to MS-DRG 299, 300, 301, with relative weights from 0.7197 to 1.6327 depending on complications. Higher weights mean higher Medicare reimbursement.

What is the ICD-9 equivalent of I87.1?

Under the General Equivalence Mappings, compression of vein converts to ICD-9-CM 459.2 (compression of vein). The mapping is a direct match.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
