R19 is a non-billable ICD-10-CM category code for other symptoms and signs involving the digestive system and abdomen, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R19.00, R19.01, R19.02, and R19.03. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

Questions About R19Overview

Is R19 a billable code?

No. This is a category header that groups the codes for other symptoms and signs involving the digestive system and abdomen, and headers cannot be submitted on claims. Claims for other symptoms and signs involving the digestive system and abdomen need a more specific code from this category, such as R19.00, R19.01, and R19.02.

Can R19 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 digestive system and abdomen is established, that condition takes the principal position instead.
