R13 is a non-billable ICD-10-CM category code for aphagia and dysphagia, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R13.0, R13.10, R13.11, and R13.12. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

Swallowing Disorders

If you have a swallowing disorder, you may have difficulty or pain when swallowing. Some people cannot swallow at all. Others may have trouble swallowing liquids, foods, or saliva. This makes it hard to eat. Often, it can be difficult to take in enough calories and fluids to nourish your body.

Questions About R13Overview

Is R13 (Aphagia and dysphagia) a billable code?

No. This is a category header that groups the codes for aphagia and dysphagia, and headers cannot be submitted on claims. Claims for aphagia and dysphagia need a more specific code from this category, such as R13.0, R13.10, and R13.11.

Can R13 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the aphagia and dysphagia is established, that condition takes the principal position instead.
