O99.213 Obesity complicating pregnancy, third trimester

Name of the Condition

• Obesity Complicating Pregnancy, Third Trimester (ICD-10 Code: O99.213)

Summary

This condition describes obesity affecting a pregnant individual during the third trimester of pregnancy. Obesity in this stage can increase the risk of complications for both the mother and the fetus, potentially impacting delivery and postpartum recovery.

Causes

Obesity is typically driven by a combination of genetic, behavioral, and environmental factors. Excessive caloric intake, sedentary lifestyle, and metabolic issues may contribute to weight gain, which can complicate pregnancy in the third trimester.

Risk Factors

• High pre-pregnancy body mass index (BMI)
• Excessive weight gain during pregnancy
• Family history of obesity
• Poor dietary habits
• Limited physical activity
• Previous pregnancies with obesity-related complications

Symptoms

• Excessive weight gain or difficulty managing weight
• Increased fatigue or shortness of breath
• Higher risk of gestational diabetes or hypertension
• Sleep disturbances (e.g., sleep apnea)
• Joint or back pain

Diagnosis

Diagnosis is based on BMI calculation, medical history, and physical examination. Healthcare providers may assess weight trends during the third trimester, along with related health markers (e.g., blood pressure, glucose levels) to identify complications.

Treatment Options

Management may include dietary modifications, supervised physical activity, and monitoring for complications. In some cases, medical interventions or specialized care may be necessary to support maternal and fetal health.

Prognosis and Follow-Up

Prognosis depends on the severity of obesity and any associated complications. Regular follow-up is essential to monitor maternal and fetal well-being, with adjustments to care plans as needed.

Complications

• Gestational diabetes
• Preeclampsia or hypertension
• Increased risk of cesarean delivery
• Fetal macrosomia (large birth weight)
• Postpartum weight retention

Lifestyle & Prevention

• Maintain a balanced diet with appropriate caloric intake
• Engage in safe, approved physical activity during pregnancy
• Monitor weight gain according to healthcare provider guidance
• Address lifestyle factors that contribute to weight gain

When to Seek Professional Help

Seek medical attention if experiencing severe symptoms such as persistent shortness of breath, sudden weight gain, or signs of preeclampsia (e.g., headaches, vision changes). Regular prenatal care is critical for managing obesity-related risks.

Tips for Medical Coders

Document the trimester (third) and confirm obesity as a complicating factor in pregnancy. Ensure clinical notes support the diagnosis and align with the specific trimester to justify code assignment.
