Questions About E55Overview

What is the ICD-10 code for vitamin D deficiency?

E55 is the ICD-10-CM category for vitamin D deficiency, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is E55 (Vitamin D deficiency) a billable code?

No. This is a category header that groups the codes for vitamin D deficiency, and headers cannot be submitted on claims. Claims for vitamin D deficiency need a more specific code from this category, such as E55.0 and E55.9.

Can E55 be reported with a code from M83?

Not as a rule. The Excludes1 note on E55 lists "adult osteomalacia (M83.-)". 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).
