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

I87.1 is a billable ICD-10-CM diagnosis code for compression of vein. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 299 through 301. 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 1 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Postthrombotic syndrome and venous insufficiency/hypertension.

What is the ICD-10 code for compression of vein?

The ICD-10-CM code for compression of vein is I87.1 (sometimes written as I871). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

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, 2026 through September 30, 2027.

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 301, 300, 299, with relative weights from 0.7132 to 1.5840 depending on complications. Higher weights mean higher Medicare reimbursement.

Is I87.1 a CC or MCC?

CMS lists I87.1 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 1 closely related codes in its exclusion list.

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.
