Q12.1 Congenital displaced lens

ICD10CM code

#### Name of the Condition
- Congenital Displaced Lens
- Also known as Ectopia Lentis.

#### Summary
- Congenital displaced lens is a condition where the lens of the eye is not properly positioned at birth. It may affect one or both eyes and can lead to visual impairment if not addressed.

#### Causes
- This condition often results from genetic mutations. It is sometimes associated with inherited disorders, such as Marfan syndrome or homocystinuria.

#### Risk Factors
- Family history of lens displacement or related genetic disorders increases the risk.
- Genetic predispositions linked to connective tissue disorders are significant factors.

#### Symptoms
- Symptoms may include blurred vision, double vision, or noticeable misalignment of the eye lens. In some cases, reduced visual acuity is observed.

#### Diagnosis
- Diagnosis is typically achieved through a comprehensive eye examination, including slit-lamp examination and observation of the lens position. Genetic testing might be suggested if a hereditary condition is suspected.

#### Treatment Options
- Treatment often involves vision correction with glasses or contact lenses. In more severe cases, surgical intervention may be necessary to reposition or replace the lens.
- Surgical procedures help restore proper vision alignment and improve overall vision quality.

#### Prognosis and Follow-Up
- With appropriate treatment, individuals can maintain good vision. Regular follow-up with an eye care specialist is crucial to monitor eye health and adjust treatments as needed.

#### Complications
- If untreated, can lead to significant visual impairment or an increased risk of retinal detachment or glaucoma.

#### Lifestyle & Prevention
- While genetic factors cannot be altered, early diagnosis and treatment can prevent severe complications. Maintaining regular eye examinations is essential.

#### When to Seek Professional Help
- Immediate medical attention is warranted if there are sudden changes in vision, eye pain, or signs of eye misalignment.

#### Tips for Medical Coders
- Ensure proper documentation of congenital nature of the condition for accurate ICD coding.
- Beware of differentiating from acquired lens displacement conditions when coding.
