R41 is a non-billable ICD-10-CM category code for other symptoms and signs involving cognitive functions and awareness, so it cannot be submitted on claims.

As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

Questions About R41Overview

Is R41 a billable code?

No. This is a category header that groups the codes for other symptoms and signs involving cognitive functions and awareness, and headers cannot be submitted on claims. Claims for other symptoms and signs involving cognitive functions and awareness need a more specific code from this category, such as R41.0, R41.1, and R41.2.

Can R41 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 cognitive functions and awareness is established, that condition takes the principal position instead.
