Patient EducationClinical

Bone Diseases

Your bones help you move, give you shape and support your body. They are living tissues that rebuild constantly throughout your life. During childhood and your teens, your body adds new bone faster than it removes old bone. After about age 20, you can lose bone faster than you make bone.

Questions About M83Overview

What is the ICD-10 code for adult osteomalacia?

M83 is the ICD-10-CM category for adult osteomalacia, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is M83 (Adult osteomalacia) a billable code?

No. This is a category header that groups the codes for adult osteomalacia, and headers cannot be submitted on claims. Claims for adult osteomalacia need a more specific code from this category, such as M83.0, M83.1, and M83.2.

Can M83 be reported with E55.0?

Not as a rule. The Excludes1 note on M83 lists "infantile and juvenile osteomalacia (E55.0)". 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).
