Concept Description

Last Updated: 2012-06-18


    Congenital anomalies are an abnormality of structure, function or body metabolism that is present at birth (even if not diagnosed until later in life) and results in physical or mental disability, or is fatal. (March of Dimes Resource Center. Birth Defects. (1998) - - Web site accessed December 12, 2007).

Identifying Congenital Anomalies

    Over time, several methods for identifying congenital anomalies have been used in MCHP research.

1. Brownell et al., 2007

    In the BabyFirst Project (2007) report, the following ICD-9-CM codes were used to identify congenital Anomalies (Note: these were identified using Repository data up to 90 days after the birth of the child):

    ICD-9-CM Code ICD Description
    277 Other and unspecified disorders of metabolism
    740 Anencephalus and similar anomalies
    741 Spina bifida
    742 Other congenital anomalies of nervous system
    743 Congenital anomalies of eye
    744 Congenital anomalies of ear, face, and neck
    745 Bulbus cordis anomalies and anomalies of cardiac septal closure
    746 Other congenital anomalies of heart
    747 Other congenital anomalies of circulatory system
    748 Congenital anomalies of respiratory system
    749 Cleft palate and cleft lip
    750 Other congenital anomalies of upper alimentary tract
    751 Other congenital anomalies of digestive system
    752 Congenital anomalies of genital organs
    753 Congenital anomalies of urinary system
    754 Certain congenital musculoskeletal deformities
    755 Other congenital anomalies of limbs
    756 Other congenital musculoskeletal anomalies
    757 Congenital anomalies of the integument
    758 Chromosomal anomalies
    759 Other and unspecified congenital anomalies

2. Brownell et al., 2008

    Chapter 3.8 Congenital Anomalies in the Manitoba Child Health Atlas Update (2008) report provides information that:

    • describes the conditions referred to as congenital anomalies in the report;

    • identifies the ICD-9-CM and ICD-10 codes and sources used to identify congenital anomalies in the report. This list was identified based on reports from the Alberta Congenital Anomalies Surveillance System (Alberta Health and Wellness, 2007) and the Canadian Congenital Anomalies in Surveillance Network (Health Canada, 2002) and then reviewed by the project Working Group. The list includes:

      • Down Syndrome,
      • neural tube defects (and specifically spina bifida),
      • anencephaly and similar anomalies,
      • hydrocephaly,
      • cleft palate and/or cleft lip,
      • 19 limb reductions,
      • congenital heart defects (and specifically hypoplastic left heart syndrome),
      • esophageal atresia/stenosis,
      • anorectal and large intestine atresia/stenosis,
      • hypospadias and epispadias,
      • gastroschisis, and
      • renal agenesis/hypoplasia.

        Please see the Congenital Anomalies ICD Codes.pdf for a list of ICD-9-CM and ICD-10-CA diagnoses codes used to identify congenital anomalies in the Child Health Atlas Update (2008) report.

    • presents the crude rates for congenital anomalies generated from the analysis and the adjusted rates for four conditions by combined geographical RHA Areas (South, Mid and North) in Manitoba, Winnipeg and the province of Manitoba.
