Questions About I95.1Overview

What is the ICD-10 code for orthostatic hypotension?

The ICD-10-CM code for orthostatic hypotension is I95.1 (sometimes written as I951). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is I95.1 (Hypotension) a billable code?

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

What MS-DRG does I95.1 group to?

When orthostatic hypotension is the principal diagnosis on an inpatient stay, it groups to MS-DRG 312 (syncope and Collapse), which carries a relative weight of 0.8659. Higher weights mean higher Medicare reimbursement.

Can I95.1 be reported with G90.3?

Not as a rule. The Excludes1 note on I95.1 lists "neurogenic orthostatic hypotension [Shy-Drager] (G90.3)". 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).
