H26.493 Other secondary cataract, bilateral

ICD10CM code

#### Name of the Condition
- Other Secondary Cataract, Bilateral
- Alternative Names: Secondary Cataract, Posterior Capsule Opacification (PCO)

#### Summary
Other secondary cataract, bilateral, refers to the clouding that occurs in both eyes following cataract surgery. This condition is characterized by a decrease in vision as the posterior capsule, which holds the new lens in place, becomes opaque.

#### Causes
Secondary cataracts are caused by the proliferation of lens epithelial cells following cataract surgery. These cells remaining after the removal of the natural lens cause the opacification of the lens capsule.

#### Risk Factors
- Previous cataract surgery
- Conditions like diabetes
- Younger age at the time of cataract surgery
- Use of certain intraocular lenses

#### Symptoms
- Blurred or dimmed vision similar to cataracts
- Glare or halos around lights
- Difficulty reading or performing tasks requiring clear vision

#### Diagnosis
- Comprehensive eye examination
- Slit lamp examination by an ophthalmologist

#### Treatment Options
- YAG laser capsulotomy: A simple outpatient procedure that uses a laser to create an opening in the cloudy capsule, restoring vision.
  
#### Prognosis and Follow-Up
- Prognosis is typically excellent post-treatment with YAG laser capsulotomy.
- Regular follow-up appointments are important to monitor eye health and detect any changes early.

#### Complications
- If untreated, secondary cataracts can lead to significant vision impairment, affecting daily activities.
- Potential risks from laser treatment, such as increased eye pressure or retinal detachment.

#### Lifestyle & Prevention
- Regular eye check-ups to monitor changes after cataract surgery.
- Protect eyes from UV light by wearing sunglasses.

#### When to Seek Professional Help
- Sudden changes in vision or vision loss
- Flashes of light or floaters that appear suddenly
- Any significant discomfort or changes in eye condition

#### Tips for Medical Coders
- Ensure coding reflects "bilateral" to indicate both eyes are affected.
- Verify if any specific details such as specific procedure codes (YAG laser) should be linked.
- Avoid confusion with primary cataracts or cataracts resulting from trauma.
