Code Description

ICD-10 Q41.2 is a billable code used to indicate a diagnosis of congenital absence, atresia and stenosis of ileum.

Key Diagnostic Point:

Congenital absence, atresia, and stenosis of the ileum are serious congenital malformations of the digestive system that can significantly impact a newborn's health. The ileum, which is the final section of the small intestine, plays a crucial role in nutrient absorption. In cases of atresia, the ileum is either absent or obstructed, leading to severe feeding difficulties and potential bowel obstruction. This condition is often diagnosed shortly after birth, typically presenting with symptoms such as bilious vomiting, abdominal distension, and failure to pass meconium. Surgical intervention is usually required to correct the malformation, and the prognosis can vary based on the severity of the condition and any associated anomalies. Congenital malformations of the digestive system, such as esophageal atresia, Hirschsprung disease, and gastroschisis, share similar challenges in diagnosis and management, emphasizing the need for comprehensive pediatric care. Early detection and intervention are critical to improving outcomes for affected infants.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and severity of the condition
  • Need for detailed surgical documentation
  • Potential for associated congenital anomalies
  • Differentiation from similar conditions (e.g., stenosis vs. atresia)

Audit Risk Factors

  • Inadequate documentation of surgical procedures
  • Failure to report associated congenital anomalies
  • Misclassification of atresia vs. stenosis
  • Lack of follow-up documentation

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

Pediatric documentation must include detailed birth history, clinical findings, and surgical reports. It is essential to document the infant's growth and development post-surgery.

Common Clinical Scenarios

Common scenarios include newborns presenting with bilious vomiting and abdominal distension, requiring immediate surgical evaluation.

Billing Considerations

Consideration must be given to the infant's overall health, potential for associated congenital anomalies, and the need for multidisciplinary care.

Genetics

Documentation Requirements

Genetic documentation should include family history, genetic testing results, and any syndromic associations with congenital malformations.

Common Clinical Scenarios

Scenarios may involve genetic counseling for families with a history of congenital digestive malformations.

Billing Considerations

Genetic coding must accurately reflect any chromosomal abnormalities or syndromes associated with the congenital condition.

Coding Guidelines

Inclusion Criteria

Use Q41.2 When
  • Official coding guidelines for congenital conditions emphasize the importance of accurate documentation of the diagnosis, surgical interventions, and any associated conditions
  • Coders should ensure that all relevant details are captured to support the medical necessity of procedures

Exclusion Criteria

Do NOT use Q41.2 When
No specific exclusions found.

Clinical Scenario

Used in cases of ileal atresia requiring diversion of intestinal contents.

Documentation Requirements

Surgical reports must detail the procedure and any complications.

Specialty Considerations

Pediatric surgeons must document the rationale for the procedure and any associated risks.

Frequently Asked Questions

What are the common surgical interventions for Q41.2?

Common surgical interventions for congenital absence, atresia, and stenosis of the ileum include resection of the affected segment and anastomosis, or creation of an ileostomy if necessary. The choice of procedure depends on the severity of the condition and the presence of any associated anomalies.
