G21.11 Neuroleptic induced parkinsonism

ICD10CM code

#### Name of the Condition
- Common Name: Neuroleptic Induced Parkinsonism
- Medical Term: G21.11

#### Summary
Neuroleptic Induced Parkinsonism is a condition characterized by symptoms similar to Parkinson's disease, such as tremors, stiffness, and slowed movement, that occurs as a side effect of antipsychotic medications known as neuroleptics.

#### Causes
This condition is caused by the use of neuroleptic medications, which are commonly prescribed for psychiatric disorders. These drugs can block dopamine receptors in the brain, leading to decreased dopamine activity, similar to what occurs in Parkinson's disease.

#### Risk Factors
- Taking high doses of neuroleptic medications.
- Long-term use of antipsychotic drugs.
- Being older or female, which may increase susceptibility.
- Pre-existing neurological conditions.

#### Symptoms
- Muscle stiffness or rigidity
- Tremors, especially in the hands
- Bradykinesia (slowed movement)
- Imbalance and unsteady walking
- Reduced facial expressions

#### Diagnosis
Diagnosis typically involves:
- Thorough medical history review, including medication history.
- Neurological examination.
- Rule out other causes of parkinsonism.

#### Treatment Options
- Adjusting or discontinuing the neuroleptic medication if possible.
- Switching to atypical antipsychotics which have a lower risk of inducing parkinsonism.
- Use of medications such as anticholinergics or amantadine to manage symptoms.

#### Prognosis and Follow-Up
- Symptoms may improve after adjusting medication, though this can vary.
- Regular follow-up is essential to monitor and manage symptoms effectively.
- In some cases, symptoms may persist even after stopping the causative medication.

#### Complications
- Persistent motor symptoms leading to decreased quality of life.
- Increased risk of falls and related injuries due to impaired balance and mobility.

#### Lifestyle & Prevention
- Regular exercise to improve muscle strength and flexibility.
- Awareness and monitoring for early symptoms if starting neuroleptic medication.
- Communication with healthcare providers about side effects.

#### When to Seek Professional Help
- Experiencing new or worsening symptoms of tremors, stiffness, or difficulty moving.
- Sudden changes in symptoms or general health.
- Concerns regarding side effects of medications.

#### Tips for Medical Coders
- Ensure accurate documentation of the medication use and related symptoms.
- Differentiate this condition from primary Parkinson's disease based on the history of neuroleptic use.
- Avoid coding errors by using the specific ICD-10 code G21.11.
