R57 is a non-billable ICD-10-CM category code for shock, not elsewhere classified, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R57.0, R57.1, R57.8, and R57.9. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

Questions About R57Overview

Is R57 (Shock, not elsewhere classified) a billable code?

No. This is a category header that groups the codes for shock, not elsewhere classified, and headers cannot be submitted on claims. Claims for shock, not elsewhere classified need a more specific code from this category, such as R57.0, R57.1, and R57.8.

Can R57 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the shock, not elsewhere classified is established, that condition takes the principal position instead.
