Z68.1 — Body mass index [BMI] 19.9 or less, adult
Not billableSubdivided FY2027
Can I still bill Z68.1?
No — Z68.1 stopped being billable on October 1, 2026. Z68.1 still exists in ICD-10-CM but was subdivided for FY2027 and became a non-billable header code. Because Z68.1 still appears in a code lookup, this change is easy to miss — but submitting it on or after October 1, 2026 will be denied for lack of specificity. Use one of the more specific codes below instead.
