Congenital absence, atresia and stricture of auditory canal (external)
ICD-10 Q16.1 is a billable code used to indicate a diagnosis of congenital absence, atresia and stricture of auditory canal (external).
Congenital absence, atresia, and stricture of the external auditory canal are conditions characterized by the incomplete development or total absence of the ear canal. This malformation can lead to conductive hearing loss and may be associated with other congenital anomalies, particularly those affecting the face and neck. The condition can occur as an isolated defect or as part of syndromic presentations, such as Goldenhar syndrome or Treacher Collins syndrome. Diagnosis is typically made through physical examination and imaging studies, such as CT scans, which can assess the anatomy of the ear structures. Management may involve surgical intervention to create a functional ear canal, hearing aids, or other supportive measures to address hearing loss. Early intervention is crucial for optimal auditory and speech development in affected children.
Documentation should include detailed descriptions of the physical examination findings, audiological assessments, and any associated congenital anomalies.
Common scenarios include newborn screening for hearing loss, referrals for audiology evaluations, and surgical consultations for canal reconstruction.
Consideration should be given to the developmental milestones of the child and the impact of hearing loss on speech and language development.
Genetic evaluations should document family history, syndromic associations, and any genetic testing results.
Scenarios may include genetic counseling for families with a history of congenital ear anomalies or syndromic conditions.
Genetic syndromes associated with ear malformations should be considered, and appropriate genetic testing should be documented.
Used for patients with Q16.1 requiring surgical intervention to create a functional ear canal.
Document the indication for surgery, pre-operative assessments, and post-operative care.
Pediatric specialists should ensure that developmental assessments are included in the surgical documentation.
Common associated conditions include other congenital ear anomalies, facial dysmorphisms, and syndromic features such as those seen in Treacher Collins syndrome or Goldenhar syndrome. Genetic counseling may be beneficial for families.
