Questions About R09.A2Overview

Is R09.A2 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report foreign body sensation, throat on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does R09.A2 group to?

When foreign body sensation, throat is the principal diagnosis on an inpatient stay, it groups to MS-DRG 314, 315, 316, with relative weights from 0.6821 to 2.0852 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R09.A2 be a principal diagnosis?

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
