Questions About M25Overview

What is the ICD-10 code for other joint disorder, not elsewhere classified?

M25 is the ICD-10-CM category for other joint disorder, not elsewhere classified, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is M25 (Other joint disorder, not elsewhere classified) a billable code?

No. This is a category header that groups the codes for other joint disorder, not elsewhere classified, and headers cannot be submitted on claims. Claims for other joint disorder, not elsewhere classified need a more specific code from this category, such as M25.00, M25.011, and M25.012.
