ICD10 code of Amniotic Band Syndrome and ICD9 code

Amniotic Band Syndrome is classified under ICD-10 code Q79.8 (Other congenital malformations of the musculoskeletal system) and was previously identified under ICD-9 code 756.79. These codes are used for medical billing and clinical documentation to describe the physical constrictions caused by fibrous bands during fetal development.

What is Amniotic Band Syndrome?

Amniotic Band Syndrome, also known as constriction ring syndrome or ADAM complex, is a rare condition where thin strands of the amnion (the inner sac surrounding the fetus) become entangled around fetal parts. This mechanical restriction can lead to limb length discrepancies, syndactyly (webbing of fingers or toes), or, in severe cases, amputations. Because Amniotic Band Syndrome is not a genetic disorder, it does not typically recur in subsequent pregnancies, providing a measure of relief for many families.

How is Amniotic Band Syndrome diagnosed and coded?

Diagnosis of Amniotic Band Syndrome is often made via prenatal ultrasound, where medical professionals identify constriction rings or limb abnormalities. While ICD-10 Q79.8 is the standard, clinicians may also use specific codes depending on the affected body part, such as Q71-Q73 for limb reduction defects. At DiseaseMaps.org, 17 community members have shared their unique experiences with Amniotic Band Syndrome, highlighting the wide spectrum of severity associated with the condition.

What are the clinical implications of the diagnosis?

The severity of Amniotic Band Syndrome varies significantly from patient to patient. Common clinical features include:

• Constriction rings around digits, limbs, or occasionally the trunk.


• Lymphedema distal to the site of the constriction.


• Syndactyly or fusion of soft tissues.


• Potential for craniofacial or visceral defects in rare, severe presentations.

Next steps

• Consult a pediatric orthopedic surgeon to discuss potential reconstructive or release surgeries.


• Seek a referral to a pediatric hand specialist if Amniotic Band Syndrome has affected the development of fingers or toes.


• Connect with the 17 members on DiseaseMaps.org to share support and long-term management strategies.


• Engage with occupational therapy to support fine motor development if limb function is impacted.
