  • pseudophakia (Z96.1)
  • secondary cataracts (H26.4-)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 7 (H00-H59) Diseases of the eye and adnexa applies to 2,677 codes
  • certain conditions originating in the perinatal period (P04-P96)

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.

The full article covers:

  • What diseases can affect the eye?
  • What are the symptoms of eye diseases?
  • Who is more likely to develop eye diseases?
  • What are the treatments for eye diseases?
  • Can eye diseases be prevented?

Questions About H59Overview

Is H59 a billable code?

No. This is a category header that groups the codes for intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified, and headers cannot be submitted on claims. Claims for intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified need a more specific code from this category, such as H59.011, H59.012, and H59.013.

Can H59 be reported with T85.2?

Not as a rule. The Excludes1 note on H59 lists "mechanical complication of intraocular lens (T85.2)". 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).
