Questions About I07.0Overview
What is the ICD-10 code for rheumatic tricuspid stenosis?
The ICD-10-CM code for rheumatic tricuspid stenosis is I07.0 (sometimes written as I070). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is I07.0 (Rheumatic tricuspid valve diseases) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report rheumatic tricuspid stenosis on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does I07.0 group to?
When rheumatic tricuspid stenosis 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 I07.0 be reported with a code from I36?
Not as a rule. The Excludes1 note at I07, which applies to I07.0, 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 I07.0?
Under the General Equivalence Mappings, rheumatic tricuspid stenosis converts to ICD-9-CM 397.0 (tricuspid valve disease). The mapping is approximate, so confirm the match fits the documentation.
