ICD-10-CM R93
CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

R93 is a non-billable ICD-10-CM category code for abnormal findings on diagnostic imaging of other body structures, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R93.0, R93.1, R93.2, and R93.3. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

Questions About R93Overview

Is R93 a billable code?

No. This is a category header that groups the codes for abnormal findings on diagnostic imaging of other body structures, and headers cannot be submitted on claims. Claims for abnormal findings on diagnostic imaging of other body structures need a more specific code from this category, such as R93.0, R93.1, and R93.2.

Can R93 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the abnormal findings on diagnostic imaging of other body structures is established, that condition takes the principal position instead.
