O36.8121 Decreased fetal movements, second trimester, fetus 1

ICD10CM code

#### Name of the Condition
- **Decreased fetal movements, second trimester, fetus 1**
- Often referred to as reduced fetal movements during mid-pregnancy.

#### Summary
- Decreased fetal movements refer to a reduction in the normal activity or movements of a fetus in the womb, detected generally by the mother. During the second trimester, decreased fetal movements can be a signal of potential issues with fetal well-being.

#### Causes
- Causes can include placental insufficiency, fetal growth restrictions, issues with the umbilical cord, or maternal health problems such as high blood pressure or diabetes.

#### Risk Factors
- Age (advanced maternal age)
- Pre-existing medical conditions (e.g., hypertension or diabetes)
- Previous pregnancy complications
- Lifestyle factors such as smoking or substance use

#### Symptoms
- Noticeable reduction in the fetal movements as previously felt by the mother, typically identified through a count of less than ten movements in two hours.

#### Diagnosis
- Ultrasound to assess fetal well-being and amniotic fluid levels
- Non-stress tests to monitor fetal heart rate
- Maternal records of fetal movement patterns

#### Treatment Options
- Close monitoring of both the mother and fetus
- Addressing underlying maternal health conditions
- Possible hospital admission for intensive monitoring in severe cases

#### Prognosis and Follow-Up
- With timely intervention, outcomes can be improved.
- Regular follow-up appointments are crucial to monitor fetal health and maternal condition.

#### Complications
- Potential for fetal distress or stillbirth if underlying issues are not addressed
- Increased risk of emergency interventions during pregnancy and delivery

#### Lifestyle & Prevention
- Maintaining a healthy lifestyle with balanced nutrition and regular prenatal care
- Avoiding harmful substances such as alcohol and tobacco
- Tracking fetal movements regularly after 28 weeks of gestation

#### When to Seek Professional Help
- If experiencing a marked reduction in fetal movements or a complete cessation
- Immediate attention required if movements are not felt after two hours of focused monitoring

#### Tips for Medical Coders
- Ensure accurate gestational period coding: this code is specific to the second trimester.
- Verify if the condition refers explicitly to fetus 1 in multiple pregnancies.
- Double-check for any additional codes that might indicate associated maternal conditions.
