Q42: ICD10 Code for Congenital absence, atresia and stenosis of large intestine

Q42 refers to Congenital absence, atresia and stenosis of large intestine, covering congenital defects affecting the mouth, esophagus, intestines, gallbladder, bile ducts, and liver that can impact digestion and nutrient absorption.

Symptoms

• Feeding difficulties – Especially in esophageal atresia (Q39)
• Vomiting and abdominal swelling – Due to intestinal blockages (Q41–Q42)
• Jaundice – Common with bile duct malformations (Q44)
• Swallowing or breathing issues – Related to mouth or pharyngeal anomalies (Q38)
• Growth retardation – Due to malabsorption or obstruction (Q43–Q45)

Diagnosis

Diagnosis typically involves prenatal imaging like ultrasound, postnatal physical examination, contrast studies (e.g., barium swallow), and sometimes surgical exploration for digestive system anomalies.

ICD10 Code Usage

ICD10 code Q42 is used to document congenital digestive defects for EHRs, surgical planning, medical coding, and early nutritional support programs.

FAQs

Q1: What is ICD10 code Q42?
A: It is used to document Congenital absence, atresia and stenosis of large intestine affecting the digestive tract or accessory organs.

Q2: Are congenital digestive anomalies life-threatening?
A: Some can be life-threatening without timely surgical or medical treatment.

Q3: How is esophageal atresia managed?
A: Surgical correction is typically performed soon after birth to restore feeding ability.

Q4: What is biliary atresia?
A: A blockage in the bile ducts that requires surgical intervention to prevent liver damage.

Q5: Can these conditions be detected before birth?
A: Yes, many major malformations are suspected during detailed prenatal ultrasound evaluations.

Conclusion

ICD10 code Q42 ensures accurate recording of Congenital absence, atresia and stenosis of large intestine, helping in early interventions, medical care coordination, and long-term digestive health outcomes for affected newborns.
