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

R09 is a non-billable ICD-10-CM category code for other symptoms and signs involving the circulatory and respiratory system, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R09.01, R09.02, R09.1, and R09.2. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

Breathing Problems

When you're short of breath, it's hard or uncomfortable for you to take in the oxygen your body needs. You may feel as if you're not getting enough air. Sometimes you can have mild breathing problems because of a stuffy nose or intense exercise. But shortness of breath can also be a sign of a serious disease.

Questions About R09Overview

Is R09 a billable code?

No. This is a category header that groups the codes for other symptoms and signs involving the circulatory and respiratory system, and headers cannot be submitted on claims. Claims for other symptoms and signs involving the circulatory and respiratory system need a more specific code from this category, such as R09.01, R09.02, and R09.1.

Can R09 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the other symptoms and signs involving the circulatory and respiratory system is established, that condition takes the principal position instead.
