Code Classification

  • Congenital malformations, deformations and chromosomal abnormalities
    (Q00-Q99)
    • Congenital malformations and deformations of the musculoskeletal system
      (Q65-Q79)
      • Syndactyly
        (Q70)

Q70.1 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of webbed fingers. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Webbed fingers

Non-specific codes like Q70.1 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for webbed fingers:

  • Use Q70.10 for Webbed fingers, unspecified hand - BILLABLE CODE

  • Use Q70.11 for Webbed fingers, right hand - BILLABLE CODE

  • Use Q70.12 for Webbed fingers, left hand - BILLABLE CODE

  • Use Q70.13 for Webbed fingers, bilateral - BILLABLE CODE

Clinical Information

  • Poland Syndrome

    a syndrome which is characterized by symbrachydactyly and aplasia of the sternal head of pectoralis major.
  • Syndactyly

    a congenital anomaly of the hand or foot, marked by the webbing between adjacent fingers or toes. syndactylies are classified as complete or incomplete by the degree of joining. syndactylies can also be simple or complex. simple syndactyly indicates joining of only skin or soft tissue; complex syndactyly marks joining of bony elements.
  • Acrocephalosyndactyly

    a genetic disorder characterized by craniosynostosis and fusion of the fingers and toes.
  • Fraser Syndrome|Cryptophthalmos-Syndactyly Syndrome

    a rare, autosomal recessive inherited disorder caused by mutations in the fras1, frem2, or grip1 genes. it is characterized by the presence of cryptophthalmos, cutaneous syndactyly, and genitourinary abnormalities.

    human gja1 wild-type allele is located in the vicinity of 6q22.31 and is approximately 14 kb in length. this allele, which encodes gap junction alpha-1 protein, plays a role in the modulation of the activity of gap junctions. mutation of the gene is associated with atrioventricular septal defect 3, autosomal recessive craniometaphyseal dysplasia, hypoplastic left heart syndrome 1, oculodentodigital dysplasia and syndactyly, type iii.
  • GLI3 Gene|GLI-Kruppel Family Member GLI3 (Greig Cephalopolysyndactyly Syndrome) Gene|GLI3|GLI3

    this gene plays a regulatory role in limb development and is involved in sonic hedgehog signal transduction.
  • GLI3 wt Allele|GCPS|GLI-Kruppel Family Member 3|GLI-Kruppel Family Member GLI3 (Greig Cephalopolysyndactyly Syndrome) wt Allele|GLI3|PAP-A|PAPA|PHS

    human gli3 wild-type allele is located in the vicinity of 7p13 and is approximately 272 kb in length. this allele, which encodes zinc finger protein gli3, plays a role in the regulation of sonic hedgehog-dependent transcription of specific genes during the development of multiple organ systems. this gene is the site of a mutation that is linked to greig cephalopolysyndactyly syndrome.
  • Greig Syndrome|GCPS|Greig Cephalopolysyndactyly Syndrome|Greig Cephalosyndactyly Syndrome|Greig's Syndrome

    an autosomal dominant genetic disorder caused by mutations in the gli3 gene. it is characterized by physical abnormalities of the fingers and/or toes (extra fingers and/ or toes, fusion of the fingers and/or toes), large size head with prominent forehead and hypertelorism.
  • Polysyndactyly

    a rare anatomical malformation characterized by polydactyly (extra fingers or toes) and syndactyly (webbed fingers or toes).
  • Sclerosteosis|Cortical Hyperostosis with Syndactyly|Cortical Hyperostosis with Syndactyly

    an autosomal recessive form of craniotubular hyperostosis due to loss-of-function mutation(s) in the sost gene, encoding sclerostin. clinical features include tall stature, enlarged jaw and facial bones, and cranial nerve compression leading to hearing loss and facial palsy. about two-thirds of patients have syndactyly and/or nail malformations. increased intracranial pressure due to the thickened calvaria and skull base can occur.
  • Syndactyly

    a congenital condition characterized by webbing between the fingers and/or toes, joining the digits together. in rare cases, the joining of the fingers or toes may involve bony fusion between the digits. common causes include down syndrome and hereditary syndactyly.
  • TWIST1 Gene|TWIST1|TWIST1|Twist Homolog 1 (Acrocephalosyndactyly 3; Saethre-Chotzen Syndrome) (Drosophila) Gene

    this gene plays a role in regulation of transcription and the inhibition of apoptosis. it is also involved in the control of morphogenesis during embryonic development.
  • TWIST1 wt Allele|ACS3|BPES2|BPES3|SCS|TWIST|Twist Homolog 1 (Acrocephalosyndactyly 3; Saethre-Chotzen Syndrome) (Drosophila) wt Allele

    human twist1 wild-type allele is located in the vicinity of 17p13.3 and is approximately 16 kb in length. this allele, which encodes twist-related protein 1, plays a role in the regulation of both transcription and cell lineage determination. mutations in the gene are associated with saethre-chotzen, robinow-sorauf, and baller-gerold syndromes.
  • Twist-Related Protein 1|Acrocephalosyndactyly 3 Protein|Class A Basic Helix-Loop-Helix Protein 38|H-Twist|TWIST|TWIST1|TWIST1 Protein|Twist Homolog|Twist Homolog 1|Twist Related Protein 1|bHLHa38

    twist-related protein 1 (202 aa, ~21 kda) is encoded by the human twist1 gene. this protein plays a role in the negative regulation of both transcription and myogenesis.
  • Type I Acrocephalosyndactyly|Acrocephalosyndactyly Type I|Apert Syndrome

    an autosomal dominant inherited type of acrocephalosyndactyly caused by mutations in the fgfr2 gene. it is characterized by early closure of the sutures between the skull bones, bulging eyes, low-set ears, fusion of the second, third, and forth fingers, and fusion of the toes.
  • Type II Acrocephalopolysyndactyly|Acrocephalopolysyndactyly Type II|Acrocephalopolysyndactyly Type II|Carpenter 's Syndrome|Carpenter Syndrome|Carpenter Syndrome

    an extremely rare autosomal recessive syndrome characterized by premature closure of cranial sutures leading to cone-shaped head, fusion of the digits, and the presence of more digits than normal. it may be associated with heart defects, single horseshoe-shaped kidney, short stature, undescended testes, and mild mental retardation.
  • Type III Acrocephalosyndactyly|Acrocephalosyndactyly Type III|Saethre-Chotzen Syndrome|Saethre-Chotzen Syndrome

    a rare autosomal dominant syndrome caused by mutations in the twist1 gene. it is characterized by premature closure of skull bones resulting in abnormally shaped head, high forehead, hypertelorism, and facial asymmetry. it may be associated with fusion of certain fingers or toes.
  • Type V Acrocephalosyndactyly|Acrocephalosyndactyly Type V|Noack Syndrome|Pfeiffer Syndrome

    an autosomal dominant inherited type of acrocephalosyndactyly caused by mutations in the fgfr1 or fgfr2 genes. it is characterized by early closure of the sutures between the skull bones, bulging and wide-set eyes, broad thumbs, big toes, and partial syndactyly in the hands and toes.
