H35.52 Pigmentary retinal dystrophy

ICD10CM code

#### Name of the Condition
- Pigmentary Retinal Dystrophy
- Also known as Retinitis Pigmentosa (RP) or H35.52 in the ICD coding system.

#### Summary
Pigmentary retinal dystrophy, commonly referred to as Retinitis Pigmentosa, is a group of genetic disorders characterized by the progressive degeneration of the retina, leading to a gradual decline in vision.

#### Causes
- Primarily caused by genetic mutations.
- Can be inherited in an autosomal dominant, autosomal recessive, or X-linked manner.

#### Risk Factors
- Family history of retinal dystrophies increases the risk.
- Certain genetic mutations are known to cause the condition.

#### Symptoms
- Night blindness is often the first symptom.
- Loss of peripheral vision, leading to tunnel vision.
- Difficulty adapting to low-light conditions.
- In advanced stages, loss of central vision.

#### Diagnosis
- Comprehensive eye examination.
- Electroretinography (ERG) to assess the electrical responses of the retina.
- Genetic testing to identify specific mutations.
- Visual field tests.

#### Treatment Options
- No cure, but management focuses on slowing progression and maximizing remaining vision.
- Vitamin A supplementation may help slow progression in some patients.
- Low vision aids and adaptive devices.
- Gene therapy and retinal implants are emerging treatments under investigation.

#### Prognosis and Follow-Up
- Vision loss is progressive and varies depending on the specific genetic mutation.
- Regular ophthalmic follow-ups are crucial to monitor changes and adjust management strategies.

#### Complications
- Significant visual impairment or blindness.
- Possible psychological impact due to declining vision.

#### Lifestyle & Prevention
- Use of UV-protective sunglasses can help protect residual vision.
- High-dose Vitamin A has shown some benefit in slowing disease progression.
- Genetic counseling is recommended for affected individuals and family planning.

#### When to Seek Professional Help
- If experiencing symptoms such as night blindness or restriction in field of vision.
- Sudden changes in vision warrant immediate attention.

- National Eye Institute (NEI)
- Retinitis Pigmentosa International (RPI)
- Foundation Fighting Blindness

#### Tips for Medical Coders
- Verify if documentation specifies 'Pigmentary Retinal Dystrophy' to apply H35.52 correctly.
- Be aware of synonymous terms like 'Retinitis Pigmentosa.'
- Ensure accuracy by cross-referencing genetic test results, if available, in the patient's medical record.
