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

R92 is a non-billable ICD-10-CM category code for abnormal and inconclusive findings on diagnostic imaging of breast, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R92.0, R92.1, R92.2, and R92.30. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

Questions About R92Overview

Is R92 a billable code?

No. This is a category header that groups the codes for abnormal and inconclusive findings on diagnostic imaging of breast, and headers cannot be submitted on claims. Claims for abnormal and inconclusive findings on diagnostic imaging of breast need a more specific code from this category, such as R92.0, R92.1, and R92.2.

Can R92 be a principal diagnosis?

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