ICD10 code of Imperforate anus and ICD9 code

The primary ICD-10 code for imperforate anus is Q42.3 (congenital absence, atresia, and stenosis of anus), while the ICD-9 code is 751.2 (atresia and stenosis of large intestine, rectum, and anal canal). These classification codes are essential for medical billing, clinical documentation, and accessing specialized care for patients born with this anorectal malformation.

What is imperforate anus and how is it classified?

Imperforate anus is a congenital condition where the anal opening is missing or blocked at birth, preventing normal stool passage. Because the severity varies significantly—ranging from simple membranes to complex fistulas connecting the rectum to the urinary tract or reproductive system—it is often categorized as part of the broader spectrum of Anorectal Malformations (ARMs). Within the medical community and on platforms like DiseaseMaps.org, where 71 members currently share their experiences, understanding the specific anatomical type of imperforate anus is vital for determining the surgical roadmap and long-term care needs.

How is the diagnosis and surgical intervention managed?

Diagnosis of imperforate anus typically occurs in the delivery room during the initial newborn physical examination. Once identified, clinicians use imaging, such as abdominal X-rays or ultrasound, to determine the distance between the rectal pouch and the skin. Treatment for imperforate anus almost always requires surgical intervention, often performed in stages. A temporary colostomy may be necessary in the neonatal period to divert stool while the surgeons plan a definitive "anoplasty" or "posterior sagittal anorectoplasty" (PSARP) to reconstruct the anal opening. Following surgery, long-term management focuses on bowel management programs to address potential issues with constipation or fecal incontinence.

Is imperforate anus associated with other conditions?

Imperforate anus is frequently associated with other congenital anomalies, which clinicians monitor using the VACTERL association acronym. This mnemonic helps specialists evaluate for potential issues in other organ systems often affected alongside imperforate anus:

• Vertebral defects


• Anal atresia (the imperforate anus itself)


• Cardiac anomalies


• TracheoEsophageal fistula


• Renal (kidney) anomalies


• Limb abnormalities

What is the psychological impact of living with this condition?

For families and individuals, the journey through the surgical and recovery stages of imperforate anus can be emotionally taxing. Chronic conditions involving bowel function can impact a child’s social development and self-esteem as they grow. Clinical psychologists emphasize that early integration into support networks is crucial. Connecting with the 71 members of the DiseaseMaps.org community provides an opportunity to share coping strategies, navigate the transition to independent bowel care, and reduce the isolation that can sometimes accompany rare anatomical differences.

Next steps

• Consult a pediatric colorectal surgeon or a pediatric urologist to discuss long-term bowel management strategies.


• Request a referral to a genetic counselor to determine if the imperforate anus is an isolated event or part of a broader genetic syndrome.


• Join the DiseaseMaps.org patient community to exchange insights with others navigating the complexities of imperforate anus.


• Maintain a detailed log of bowel habits and surgical history to assist your multidisciplinary care team in tracking progress.
