What Is Cataract? Meaning, Snowflake, Sunflower & Christmas Tree Types, and ICD-10 Explained

What is cataract, what do snowflake, sunflower and Christmas tree cataracts mean, and what is a cataract ICD-10 code? 

This short guide from Save Sight Centre, Delhi, answers those three questions in plain language, reviewed by Dr. Rajeev Jain.

Quick Answer

A cataract is a clouding of the eye’s natural lens, which makes vision blurry, dim or hazy. Most cataracts come with age. A few rare patterns, called snowflake, sunflower and Christmas tree cataracts, are named for how they look and are often linked to a health condition elsewhere in the body. “ICD-10” is simply the code your doctor uses to record a cataract diagnosis on medical and insurance papers.

Key Takeaways

• A cataract is a cloudy lens. It is not a film on the surface of the eye.
• Snowflake, sunflower and Christmas tree cataracts are rare patterns, and they are not caused by the weather or by anything you ate.
• ICD-10 codes classify the cataract type, and some versions also record which eye.
• Only an eye examination can tell you which type you have.

What is cataract? (Cataract meaning)

Your eye has a clear natural lens behind the coloured iris. It focuses light onto the retina, the screen at the back of the eye. When that lens turns cloudy, less light gets through, and the world looks like a fogged-up window.

Cataract meaning in Hindi and Telugu: In Hindi it is motiyabind (मोतियाबिंद). In Telugu it is shuklalu (శుక్లాలు).

Common signs include blurry or dim vision, glare from headlights, trouble seeing at night, colours looking faded, and frequent changes in your glasses number. Ageing is the most common cause. Diabetes, eye injury, long UV exposure, smoking and long-term steroid use can bring it on earlier.

What are snowflake, sunflower and Christmas tree cataracts?

Eye doctors use these names for rare patterns they see under the microscope. Each one is often linked to a condition elsewhere in the body, so a doctor may advise further tests.

Snowflake cataract

• What it looks like: White, flaky cloudiness in the lens.
• Linked to: Poorly controlled diabetes, mostly in younger people.
• Good to know: It can progress quickly, so a young person with sudden blurry vision should be checked promptly.

Sunflower cataract

• What it looks like: A petal-like, sunflower pattern, often with a yellow, green or brownish tint.
• Linked to: Copper deposits in the lens. The two main causes are Wilson’s disease and a copper-containing foreign body in the eye.
• Good to know: Treating the underlying copper problem is part of the care.

Christmas tree cataract

• What it looks like: Shiny, multicoloured, needle-like deposits that sparkle like tinsel.
• Linked to: Myotonic dystrophy, a muscle condition.
• Good to know: Over the years it can turn into the more usual wedge-shaped or star-shaped cloudiness.

Do these cataracts need surgery? Surgery is considered once the cloudiness affects daily life. Your doctor will also look at the health condition behind it.

What does “cataract ICD-10” mean?

ICD-10 stands for the International Classification of Diseases, 10th revision. Hospitals use it to record a diagnosis in the same way everywhere, which matters for your reports, insurance and TPA claims.

For cataract, the main groups for Code and What it covers are:

H25 - Age-related cataract (the usual type)

H26 - Other cataract: infantile and juvenile, injury-related, drug-induced, secondary and others

Q12.0 - Congenital cataract (present from birth). It is kept separate from H26.

“Right eye cataract ICD-10”: The ICD-10-CM version adds the eye to the code. For example, H25.11 is an age-related nuclear cataract in the right eye. H25.12 is the left eye and H25.13 is both eyes.

Diabetes link: A cataract caused by diabetes can be recorded under the diabetes code instead, for example E11.36 in ICD-10-CM. Your hospital’s coding team chooses the exact code, and you don’t need to pick one yourself.

FAQs

Is a cataract the same as a film over the eye? No. A cataract is a clouded lens inside the eye, not something on the surface.

Is a snowflake cataract the same as an ordinary diabetic cataract? Not exactly. A snowflake cataract is a rare, rapid-onset pattern seen in younger people with poorly controlled diabetes. People with diabetes can also develop ordinary cataracts earlier.

Can a cataract be seen without an eye test? In advanced cases the pupil can look whitish. Most cataracts, though, are only found in an eye examination.

Which ICD-10 code will appear on my report? It depends on your cataract type and which eye is affected. Your doctor or coding team assigns it.
