Questions About F50Overview

What is the ICD-10 code for eating disorders?

F50 is the ICD-10-CM category for eating disorders, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is F50 (Eating disorders) a billable code?

No. This is a category header that groups the codes for eating disorders, and headers cannot be submitted on claims. Claims for eating disorders need a more specific code from this category, such as F50.00, F50.010, and F50.011.

Can F50 be reported with R63.0?

Not as a rule. The Excludes1 note on F50 lists "anorexia NOS (R63.0)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
