Eye Diseases

Even if your eyes feel healthy, you could have a problem and not know it. That's why regular eye exams are so important. Refractive errors are the most common type of vision problem that makes it hard to see clearly. But some eye conditions or diseases don't have any symptoms and can lead to a permanent loss of vision.

  • What are the treatments for eye diseases?
  • Can eye diseases be prevented?

Questions About H27Overview

What is the ICD-10 code for other disorders of lens?

H27 is the ICD-10-CM category for other disorders of lens, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is H27 (Other disorders of lens) a billable code?

No. This is a category header that groups the codes for other disorders of lens, and headers cannot be submitted on claims. Claims for other disorders of lens need a more specific code from this category, such as H27.00, H27.01, and H27.02.

Can H27 be reported with a code from Q12?

Not as a rule. The Excludes1 note on H27 lists "congenital lens malformations (Q12.-)". 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).
