CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

R89.1 is a billable ICD-10-CM diagnosis code for abnormal level of hormones in specimens from other organs, systems and tissues. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 947 through 948. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Abnormal findings without diagnosis.

Questions About R89.1Overview

Is R89.1 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report abnormal level of hormones in specimens from other organs, systems and tissues on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does R89.1 group to?

When abnormal level of hormones in specimens from other organs, systems and tissues is the principal diagnosis on an inpatient stay, it groups to MS-DRG 947, 948, with relative weights from 0.8005 to 1.2694 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R89.1 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the abnormal level of hormones in specimens from other organs, systems and tissues is established, that condition takes the principal position instead.

What is the ICD-9 equivalent of R89.1?

Under the General Equivalence Mappings, abnormal level of hormones in specimens from other organs, systems and tissues converts to ICD-9-CM 792.9 (abn find-body subst NEC). The mapping is approximate, so confirm the match fits the documentation.

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.
