Infantile spinal muscular atrophy, type I [Werdnig-Hoffman] G12.0 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
Spinal muscular atrophy 1 (SMA1), also known as Werdnig Hoffmann disease, is a genetic neuromuscular disorder that affects the nerve cells that control voluntary muscles (motor neurons).
Without treatment, symptoms of SMA1 become apparent before 6 months of age and include worsening muscle weakness and poor muscle tone (hypotonia) due to loss of the lower motor neurons in the spinal cord and brain stem. Feeding and breathing problems are also present.
Routine newborn screening for SMA is becoming increasingly commonplace in developed countries, given the availability of causative treatments that are most effective at the asymptomatic stage of the disease.

Spinal muscular atrophy 1 (SMA1), also known as Werdnig Hoffmann disease, is a genetic neuromuscular disorder that affects the nerve cells that control voluntary muscles (motor neurons).
Spinal muscular atrophy is a genetic disorder characterized by weakness and wasting (atrophy ) in muscles used for movement (skeletal muscles). It is caused by a loss of specialized nerve cells, called motor neurons that control muscle movement.
I63. 9 - Cerebral infarction, unspecified | ICD-10-CM.
Amyotrophy is an asymmetric lower limb motor neuropathy also known as diabetic lumbosacral plexus neuropathy and Bruns-Garland syndrome. Patients typically present with an asymmetric, painful muscle wasting and weakness affecting the lower limbs and loss of reflexes and objective weakness on examination.
Children with type 1 have limited movement, can't sit without support, and have trouble breathing, feeding, and swallowing. Symptoms begin at birth or within the first six months of life. Many children with type 1 do not live past age 2. Type 2 is an intermediate form of SMA.
Genetic test: This blood test identifies problems with the SMN1 gene. As a diagnostic tool, a genetic test is 95% effective at finding the altered SMN1 gene. Some states test for SMA as part of routine newborn screenings.
SMA is considered a rare disease. It's passed from parents to children through their genes. Only 1 in every 6,000 to 10,000 people are born with the disease. The disease course of SMA can vary significantly depending on the type.
A Word From Verywell. While muscular dystrophy can cause muscle atrophy, they are not the same condition. Muscular dystrophy is a genetic condition encompassing nine main types, while muscle atrophy refers to the loss of muscle tissue. Muscle atrophy can often be reversed with treatments and exercise.
Clinical trials for SMA gene therapy have shown clear efficacy in young children with SMA type 1, resulting in a decreased need for respiratory support as well as improvement in motor skills. Research trials have also shown that the earlier children receive gene therapy for SMA, the better the results.
What are the genetic causes of SMA? The most common form of SMA (types 1-4) is caused by a defect (mutation) in the SMN1 gene on chromosome 5. (People have two SMN1 genes — one on each chromosome 5). In 94% of all SMA cases, this mutation involves a deletion in a segment known as exon 7.
G12.0 is a valid billable ICD-10 diagnosis code for Infantile spinal muscular atrophy, type I [Werdnig-Hoffman] . It is found in the 2021 version of the ICD-10 Clinical Modification (CM) and can be used in all HIPAA-covered transactions from Oct 01, 2020 - Sep 30, 2021 .

Infants with spinal muscular atrophy 1 (SMA1) experience severe weakness before 6 months of age. Muscle weakness, lack of motor development and poor muscle tone ( hypotonia) are the major features of SMA1. [7] [8] Infants with the poorest outlook have problems with breathing and feeding (sucking and/or swallowing). [2] [7] [8] Some children develop scoliosis (curvature of the spine) or other skeletal abnormalities. Intellectual development is usually normal. [8] Affected children are not able to sit up or stand, and the vast majority do not survive past 2 years of age due to respiratory failure. [2] [9] [8]
Spinal muscular atrophy 1 (SMA1), also known as Werdnig Hoffmann disease, is a genetic neuromuscular disorder that affects the nerve cells that control voluntary muscles (motor neurons). Without treatment, symptoms of SMA1 become apparent before 6 months of age and include worsening muscle weakness and poor muscle tone ( hypotonia) due to loss of the lower motor neurons in the spinal cord and brain stem. Feeding and breathing problems are also present. [1] SMA1 is caused by changes (pathogenic variants also called mutations) in the SMN1 gene and is typically inherited in an autosomal recessive manner. [1] [2]
Genetic testing for spinal muscular atrophy 1 (SMA1) is available. Carrier testing for at-risk relatives and prenatal testing for pregnancies at increased risk are possible , if the disease-causing mutations in the family have been identified. SMA1 is caused by mutations in the SMN1 gene, and extra copies of the SMN2 gene affect the severity of the condition. [11]
Feeding and breathing problems are also present. [1] . SMA1 is caused by changes (pathogenic variants also called mutations) in the SMN1 gene and is typically inherited in an autosomal recessive manner. [1] [2] Diagnosis of SMA1 is suspected by symptoms and confirmed by genetic testing.
Spinal muscular atrophy 1 (SMA1) is inherited in an autosomal recessive manner. This means that to be affected, a person must have a change ( mutation) in both copies of the responsible gene in each cell. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers.
Approximately 2% of cases of SMA1 are not inherited from both parents. In these cases, the affected person inherits one mutated copy of the gene from one carrier parent, and has a new mutation that occurs for the first time in the other copy of the gene. [10] Last updated: 1/22/2015.
Currently, the consensus is that the phenotype of spinal muscular atrophy spans a continuum of symptoms without clear delineation of subtypes. However, the traditional classification, outlined in the table below, is still used today both in clinical research and sometimes, controversially, as a criterion of access to therapies.
The incidence of spinal muscular atrophy worldwide varies from about 1 in 4,000 births to around 1 in 16,000 births, with 1 in 7,000 and 1 in 10,000 commonly quoted for Europe and the US respectively.
Spinal muscular atrophy is inherited in an autosomal recessive pattern, which means that the defective gene is located on an autosome. Two copies of the defective gene – one from each parent – are required to inherit the disorder: the parents may be carriers and not personally affected.
Unless offered respiratory support and/or pharmacological treatment early, babies diagnosed with SMA type 1 do not generally survive past two years of age.
Associated problems may include poor head control, difficulties swallowing, scoliosis, and joint contractures. The age of onset and the severity of symptoms form the basis of the traditional classification of spinal muscular atrophy into a number of types.
Muscles of lower extremities are usually affected first, followed by muscles of upper extremities, spine and neck and, in more severe cases, pulmonary and mastication muscles. Proximal muscles are always affected earlier and to a greater degree than distal muscles.
5q SMA is a single disease that manifests over a wide range of severity, affecting infants through adults. Before its genetics was understood, its varying manifestations were thought to be different diseases – Werdnig–Hoffmann disease when young children were affected and Kugelberg–Welander disease for late-onset cases.
