ICD-10-CM R89
CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

R89 is a non-billable ICD-10-CM category code for abnormal findings in specimens from other organs, systems and tissues, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R89.0, R89.1, R89.2, and R89.3. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

Questions About R89Overview

Is R89 a billable code?

No. This is a category header that groups the codes for abnormal findings in specimens from other organs, systems and tissues, and headers cannot be submitted on claims. Claims for abnormal findings in specimens from other organs, systems and tissues need a more specific code from this category, such as R89.0, R89.1, and R89.2.

Can R89 be a principal diagnosis?

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