Code Description

ICD-10 P07.35 is a billable code used to indicate a diagnosis of preterm newborn, gestational age 32 completed weeks.

Key Diagnostic Point:

P07.35 refers to a preterm newborn who has reached a gestational age of 32 completed weeks. This classification is critical in neonatology as it helps healthcare providers identify infants who may be at risk for various complications due to their early arrival. Preterm infants, particularly those born before 34 weeks, often face challenges such as respiratory distress syndrome, feeding difficulties, and increased susceptibility to infections. Maternal factors such as hypertension, diabetes, and infections can contribute to preterm birth, while delivery complications like placental abruption or preterm premature rupture of membranes (PPROM) can also play a significant role. The care of these infants typically involves a multidisciplinary approach, including neonatologists, nurses, and lactation consultants, to address their unique needs and promote optimal growth and development. Accurate coding of this condition is essential for appropriate management and resource allocation in neonatal intensive care units (NICUs).

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation of preterm infants
  • Need for detailed maternal history and delivery complications
  • Potential for co-morbid conditions requiring additional coding
  • Documentation of gestational age and birth weight

Audit Risk Factors

  • Inaccurate gestational age documentation
  • Failure to document maternal health factors
  • Misclassification of birth weight
  • Omission of associated conditions

Specialty Focus

Neonatology

Documentation Requirements

Detailed records of gestational age, birth weight, and any complications during delivery.

Common Clinical Scenarios

Management of respiratory distress syndrome, feeding intolerance, and temperature regulation in the NICU.

Billing Considerations

Close monitoring for potential complications such as intraventricular hemorrhage and necrotizing enterocolitis.

Pediatrics

Documentation Requirements

Comprehensive history of maternal health and delivery complications, as well as follow-up care documentation.

Common Clinical Scenarios

Outpatient follow-up for growth and development assessments in preterm infants.

Billing Considerations

Awareness of long-term developmental outcomes and potential need for early intervention services.

Coding Guidelines

Inclusion Criteria

Use P07.35 When
  • According to ICD
  • 10 guidelines, accurate coding for P07
  • 35 requires documentation of gestational age at birth, any maternal complications, and the infant's clinical status
  • Coders should ensure that all relevant details are captured to support the diagnosis

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of preterm conditions, improving the ability to track outcomes and resource utilization in neonatal care. P07.35 provides a clear classification for infants born at 32 weeks, facilitating better management and research.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of preterm conditions, improving the ability to track outcomes and resource utilization in neonatal care. P07.35 provides a clear classification for infants born at 32 weeks, facilitating better management and research.

Reimbursement & Billing Impact
