All codes under H27

H27 can't be used on a claim. Pick a billable code below; grey headings group them.

H27 MS-DRGs

About the condition

Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.

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.
