ICD-10-CM O87.0
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

O87.0 is a billable ICD-10-CM diagnosis code for superficial thrombophlebitis in the puerperium. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 769, 776. 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 250 closely related codes. The code is restricted by the Medicare Code Editor to maternity cases (age 9 through 64). Coders also document this condition as bilateral lower limb vein thrombophlebitis. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Acute phlebitis; thrombophlebitis and thromboembolism and Complications specified during the puerperium.

The ICD-10-CM code for superficial thrombophlebitis in the puerperium is O87.0 (sometimes written as O870). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is O87.0 (Venous complications and hemorrhoids in the puerperium) a billable code?

What MS-DRG does O87.0 group to?

When superficial thrombophlebitis in the puerperium is the principal diagnosis on an inpatient stay, it groups to MS-DRG 769, 776, with relative weights from 0.6718 to 1.6666 depending on complications. Higher weights mean higher Medicare reimbursement.

Is O87.0 a CC or MCC?
