2007 ICD-9-CM Volume 1 Diagnosis Codes Home > Congenital Anomalies 740-759 > ICD-9-CM Diagnosis 741 Spina bifida Congenital defects of closure of one or more vertebral arches, which may be associated with malformations of the spinal cord, nerve roots, congenital fibrous bands, lipomas, and congenital cysts. These malformations range from mild (e.g., SPINA BIFIDA OCCULTA) to severe, including rachischisis where there is complete failure of neural tube and spinal cord fusion, resulting in exposure of the spinal cord at the surface. Spinal dysraphism includes all forms of spina bifida. The open form is called SPINA BIFIDA CYSTICA and the closed form is SPINA BIFIDA OCCULTA. (From Joynt, Clinical Neurology, 1992, Ch55, p34) 741 is a non-specific code that cannot be used to specify a diagnosis ICD-9-CM Diagnosis 741.0 Spina bifida with hydrocephalus 741.0 is a non-specific code that cannot be used to specify a diagnosis 741.0 contains 46 index entries ICD-9-CM Diagnosis 741.00 Spina bifida unspecified region with hydrocephalus 741.00 is a specific code that can be used to specify a diagnosis ICD-9-CM Diagnosis 741.01 Spina bifida cervical region with hydrocephalus 741.01 is a specific code that can be used to specify a diagnosis ICD-9-CM Diagnosis 741.02 Spina bifida dorsal (thoracic) region with hydrocephalus 741.02 is a specific code that can be used to specify a diagnosis ICD-9-CM Diagnosis 741.03 Spina bifida lumbar region with hydrocephalus 741.03 is a specific code that can be used to specify a diagnosis ICD-9-CM Diagnosis 741.9 Spina bifida without mention of hydrocephalus A form of spinal dysraphism associated with a protruding cyst made up of either meninges (i.e., a MENINGOCELE) or meninges in combination with spinal cord tissue (i.e., a MENINGOMYELOCELE). These lesions are frequently associated with spinal cord dysfunction, HYDROCEPHALUS, and SYRINGOMYELIA. (From Davis et al., Textbook of Neuropathology, 2nd ed, pp224-5) Congenital, or rarely acquired, herniation of meningeal and spinal cord tissue through a bony defect in the vertebral column. The majority of these defects occur in the lumbosacral region. Clinical features include PARAPLEGIA, loss of sensation in the lower body, and incontinence. This condition may be associated with the ARNOLD-CHIARI MALFORMATION and HYDROCEPHALUS. (From Joynt, Clinical Neurology, 1992, Ch55, pp35-6) 741.9 is a non-specific code that cannot be used to specify a diagnosis 741.9 contains 18 index entries ICD-9-CM Diagnosis 741.90 Spina bifida unspecified region without hydrocephalus 741.90 is a specific code that can be used to specify a diagnosis 741.90 contains 1 index entry ICD-9-CM Diagnosis 741.91 Spina bifida cervical region without hydrocephalus 741.91 is a specific code that can be used to specify a diagnosis ICD-9-CM Diagnosis 741.92 Spina bifida dorsal (thoracic) region without hydrocephalus 741.92 is a specific code that can be used to specify a diagnosis ICD-9-CM Diagnosis 741.93 Spina bifida lumbar region without hydrocephalus 741.93 is a specific code that can be used to specify a diagnosis
