ICD-10-CM
Pyelonephritis in Pregnancy

Understanding pyelonephritis in pregnancy is crucial for optimal patient care. This resource provides information on clinical documentation, medical coding (ICD-10 codes O23.0, N10, N11), and healthcare guidelines for diagnosing and managing acute pyelonephritis during pregnancy. Learn about symptoms, risk factors, treatment options, and the importance of accurate documentation for this serious pregnancy complication. Find details on kidney infection in pregnancy, gestational pyelonephritis, and appropriate medical coding for accurate reimbursement.

Documentation Best Practices

Documentation Checklist
  • Document fever, flank pain, and/or nausea/vomiting.
  • Urinalysis showing pyuria, bacteriuria documented.
  • Urine culture with positive bacterial growth specified.
  • Document symptom onset and duration for accurate coding.
  • Specify trimester of pregnancy for accurate diagnosis coding.

Coding and Audit Risks

Common Risks
  • Unspecified Laterality

    Coding pyelonephritis without specifying right, left, or bilateral can lead to rejected claims and inaccurate data reporting. Use O23.0XX for unspecified.

  • Sepsis Miscoding

    Overcoding sepsis with pyelonephritis when clinical indicators are not met can trigger audits. Properly document sepsis criteria.

  • Missing Pre-existing HTN

    Failing to code pre-existing hypertension complicating pregnancy alongside pyelonephritis can impact risk adjustment and reimbursement. Code O10.XX-

Mitigation Tips

Best Practices
  • Document fever, flank pain, and positive urine culture for accurate ICD-10 coding (N10, O23.0).
  • Capture symptom onset, duration, and severity for improved CDI and risk adjustment.
  • Order urine C&S and CBC with diff to support diagnosis and meet quality metrics.
  • Ensure proper documentation of antibiotic selection and patient education for compliance.
  • Monitor patient response to treatment and document follow-up for optimal care and coding (Z39.81).

Clinical Decision Support

Checklist
  • Verify fever >= 38C or 100.4F documented
  • Confirm flank pain or costovertebral angle tenderness
  • Check urinalysis for pyuria or bacteriuria
  • Positive urine culture or other infection signs
  • Assess for risk factors: dehydration, prior UTI

Reimbursement and Quality Metrics

Impact Summary
  • Pyelonephritis in pregnancy reimbursement hinges on accurate ICD-10-CM O23.x and appropriate DRG assignment (e.g., 635, 636) maximizing case mix index.
  • Coding quality impacts sepsis/severe sepsis reporting. Accurate documentation of infection severity is crucial for appropriate POA assignment.
  • Timely and effective treatment documented improves quality metrics related to maternal morbidity and length of stay. Avoid hospital readmissions.
  • Coding validation and physician query processes for principal diagnosis, secondary diagnoses (e.g., UTI, dehydration) ensure optimal reimbursement.

Documentation Templates

Patient presents with complaints consistent with pyelonephritis in pregnancy.  Symptoms include fever, chills, flank pain, costovertebral angle tenderness, nausea, vomiting, and dysuria.  Onset of symptoms began approximately [duration] ago.  Patient is currently in her [trimester] trimester at [gestational age] weeks.  Vital signs include temperature of [temperature], heart rate of [heart rate], respiratory rate of [respiratory rate], and blood pressure of [blood pressure].  Physical exam reveals [relevant findings, e.g., right flank tenderness, suprapubic tenderness].  Urine dipstick is positive for leukocyte esterase and nitrites.  Suspecting acute pyelonephritis, a urine culture and sensitivity has been ordered.  Differential diagnoses include cystitis, appendicitis, preterm labor, and other infectious processes.  Given the patient's pregnancy and the severity of symptoms, inpatient admission is recommended for intravenous antibiotic therapy with [antibiotic name] as per obstetric and infectious disease consultation.  Treatment plan includes monitoring of maternal and fetal well-being, serial urine cultures, and complete blood count monitoring.  Patient education provided on pyelonephritis during pregnancy, including potential complications such as preterm labor, sepsis, and acute kidney injury.  Discharge planning will include a course of oral antibiotics and close follow-up with obstetrics and primary care.  Coding considerations include acute pyelonephritis in pregnancy, urinary tract infection in pregnancy, and sepsis in pregnancy.
