ICD10 code of Klippel-Feil Syndrome and ICD9 code

Klippel-Feil Syndrome is classified under the ICD-10-CM code Q76.1, which corresponds to "Klippel-Feil syndrome." In the older ICD-9-CM classification system, the condition was identified by the code 756.16.

What is the clinical definition of Klippel-Feil Syndrome?

Klippel-Feil Syndrome is a rare congenital condition characterized by the abnormal fusion of two or more cervical (neck) vertebrae. This fusion restricts neck mobility and can lead to a classic clinical triad of a short neck, a low hairline at the back of the head, and limited range of motion in the neck. Because the skeletal structure is altered in Klippel-Feil Syndrome, patients may experience secondary issues such as chronic neck pain, headaches, or nerve compression. With over 360 members currently sharing their experiences on DiseaseMaps.org, we recognize that the severity of Klippel-Feil Syndrome varies significantly from person to person, ranging from asymptomatic cases to those requiring surgical intervention.

How are the ICD codes used for Klippel-Feil Syndrome?

Medical coding systems like ICD-10 and ICD-9 are essential for healthcare providers, insurance companies, and researchers to track the prevalence and management of Klippel-Feil Syndrome. The ICD-10 code Q76.1 is specifically used in clinical documentation to ensure that medical records accurately reflect the congenital nature of the spinal fusion. Utilizing these specific codes is critical for obtaining insurance authorization for necessary imaging, such as MRI or CT scans, which are often required to monitor the stability of the cervical spine in individuals living with Klippel-Feil Syndrome.

What clinical features should patients monitor?

While the fusion of vertebrae is the hallmark of Klippel-Feil Syndrome, the condition can also involve other organ systems. It is important for patients and caregivers to be aware of associated findings that may require specialist consultation. Common clinical associations include:

• Neurological symptoms: Numbness, tingling, or weakness in the extremities, often caused by spinal cord compression.


• Scoliosis: Curvature of the spine occurs in approximately 30% to 60% of people with Klippel-Feil Syndrome.


• Renal abnormalities: Kidney or urinary tract issues are found in roughly 25% of cases.


• Hearing and vision: Auditory or ocular impairments are reported in a subset of patients with Klippel-Feil Syndrome.


• Cardiac involvement: Congenital heart defects may occur in some individuals.

Is Klippel-Feil Syndrome considered a genetic condition?

The inheritance pattern of Klippel-Feil Syndrome is complex and not fully understood. While some cases appear to be sporadic, others show evidence of autosomal dominant or autosomal recessive inheritance. Genetic mutations in genes such as GDF6, GDF3, and MEOX1 have been linked to the development of Klippel-Feil Syndrome in certain families. Because the genetic landscape of Klippel-Feil Syndrome is still being mapped by clinical researchers, genetic counseling is highly recommended for families planning to have children.

Next steps

• Consult a pediatric or adult orthopedist or a neurosurgeon who specializes in spinal deformities.


• Request a full spinal evaluation, including imaging, to assess the extent of the vertebral fusion in Klippel-Feil Syndrome.


• Connect with the community of 360+ members on DiseaseMaps.org to share coping strategies and insights.


• Monitor for any changes in neurological function and report them to your primary care physician immediately.
