O85 Puerperal sepsis

Name of the Condition

• Puerperal Sepsis (O85)

Summary

Puerperal sepsis is a serious infection occurring during the postpartum period, typically within 42 days of delivery. It involves systemic inflammation and can affect the uterus, surrounding tissues, or other organs, requiring prompt medical intervention to prevent severe complications.

Causes

The condition is caused by bacterial infection, most commonly from ascending pathogens introduced during childbirth or postpartum procedures. These may include group A Streptococcus, Escherichia coli, or other organisms that enter the reproductive tract and spread systemically.

Risk Factors

• Prolonged labor or membrane rupture.
• Instrumental delivery (e.g., forceps, vacuum extraction).
• Cesarean section or other surgical interventions.
• Pre-existing maternal infections (e.g., chorioamnionitis).
• Poor perineal hygiene or wound care.
• Immunocompromised states.

Symptoms

• Fever (≥38°C or 100.4°F) or hypothermia (<36°C or 96.8°F).
• Pelvic or abdominal pain, tenderness, or foul-smelling vaginal discharge.
• Tachycardia (elevated heart rate) or tachypnea (rapid breathing).
• Malaise, chills, or signs of systemic infection.
• In severe cases, septic shock or organ dysfunction.

Diagnosis

Diagnosis is based on clinical presentation (fever, pain, or discharge) plus laboratory or imaging findings. Blood cultures, vaginal swabs, or imaging (e.g., ultrasound) may identify the source of infection. Criteria include fever and one or more systemic or local signs of infection within the postpartum period.

Treatment Options

• Antibiotics: Broad-spectrum IV antibiotics (e.g., penicillin, clindamycin) are initiated empirically and adjusted based on culture results.
• Surgical Intervention: May be required for abscess drainage, wound debridement, or hysterectomy in severe cases.
• Supportive Care: Fluid resuscitation, oxygen, and monitoring for organ failure.

Prognosis and Follow-Up

With early treatment, most patients recover fully. Delayed care increases risks of sepsis, organ damage, or mortality. Follow-up includes monitoring for recurrence, wound healing, and addressing any underlying causes (e.g., retained products of conception).

Complications

• Sepsis or septic shock.
• Pelvic abscess or necrotizing fasciitis.
• Organ failure (e.g., renal, respiratory).
• Postpartum hemorrhage or hysterectomy.
• Long-term disability or mortality in severe cases.

Lifestyle & Prevention

• Strict adherence to aseptic techniques during delivery and postpartum care.
• Prompt treatment of infections (e.g., urinary tract, wound infections).
• Good perineal hygiene and wound care.
• Vaccination (e.g., influenza, COVID-19) to reduce infection risk.

When to Seek Professional Help

Seek immediate care for fever, severe pain, or signs of shock (e.g., dizziness, confusion) after delivery. Persistent discharge, worsening symptoms, or failure to improve with treatment also warrant urgent evaluation.

Tips for Medical Coders

Code O85 is assigned for puerperal sepsis, a postpartum infection. Documentation should specify the infection site (e.g., uterus, pelvis) and clinical findings (e.g., fever, discharge) to support the diagnosis. Exclude codes for non-infectious postpartum complications. Ensure alignment with clinical notes and coding guidelines for accuracy.
