R47 is a non-billable ICD-10-CM category code for speech disturbances, not elsewhere classified, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R47.01, R47.02, R47.1, and R47.81. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

Questions About R47Overview

Is R47 (Speech disturbances, not elsewhere classified) a billable code?

No. This is a category header that groups the codes for speech disturbances, not elsewhere classified, and headers cannot be submitted on claims. Claims for speech disturbances, not elsewhere classified need a more specific code from this category, such as R47.01, R47.02, and R47.1.

Can R47 be a principal diagnosis?

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