Questions About I07.1Overview

What is the ICD-10 code for rheumatic tricuspid insufficiency?

The ICD-10-CM code for rheumatic tricuspid insufficiency is I07.1 (sometimes written as I071). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is I07.1 (Rheumatic tricuspid valve diseases) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report rheumatic tricuspid insufficiency on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does I07.1 group to?

When rheumatic tricuspid insufficiency is the principal diagnosis on an inpatient stay, it groups to MS-DRG 306, 307, with relative weights from 0.9146 to 1.5457 depending on complications. Higher weights mean higher Medicare reimbursement.

Can I07.1 be reported with a code from I36?

Not as a rule. The Excludes1 note at I07, which applies to I07.1, lists "tricuspid valve disease specified as nonrheumatic (I36.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

What is the ICD-9 equivalent of I07.1?

Under the General Equivalence Mappings, rheumatic tricuspid insufficiency converts to ICD-9-CM 397.0 (tricuspid valve disease). The mapping is approximate, so confirm the match fits the documentation.
