All codes under H26

H26 can't be used on a claim. Pick a billable code below; grey headings group them.

H26 MS-DRGs

As the principal diagnosis, all 69 billable codes under H26 group to MS-DRG 124 or 125 (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.

About the condition

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

Cataract

A cataract is a clouding of the clear lens inside your eye. This cloudiness blocks light from reaching the back of the eye, making it harder to see clearly. A cataract can affect one or both eyes, but it doesn't spread from one eye to the other.
