Questions About K01Overview

What is the ICD-10 code for embedded and impacted teeth?

K01 is the ICD-10-CM category for embedded and impacted teeth, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is K01 (Embedded and impacted teeth) a billable code?

No. This is a category header that groups the codes for embedded and impacted teeth, and headers cannot be submitted on claims. Claims for embedded and impacted teeth need a more specific code from this category, such as K01.0 and K01.1.

Can K01 be reported with a code from M26.3?

Not as a rule. The Excludes1 note on K01 lists "abnormal position of fully erupted teeth (M26.3-)". 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).
