Postauricular fistula
ICD-10 H70.81 is a billable code used to indicate a diagnosis of postauricular fistula.
Postauricular fistula is a congenital or acquired abnormal connection between the skin of the postauricular area and the underlying structures, often associated with the ear and mastoid process. This condition can manifest as a small pit or sinus located behind the ear, which may become infected or inflamed, leading to discharge and discomfort. Clinically, patients may present with recurrent infections, pain, or drainage from the fistula, particularly during episodes of otitis media or mastoiditis. Diagnosis typically involves a thorough clinical examination, imaging studies such as CT scans to assess the extent of the fistula, and possibly cultures of any discharge to rule out specific pathogens. Management may include surgical intervention to excise the fistula, especially if recurrent infections occur. Postauricular fistulas can be associated with other ear anomalies, and thus, a comprehensive evaluation of the ear and surrounding structures is essential for effective treatment and management.

Ensure all relevant imaging and surgical details are documented to support coding.
History of ear infections, family history of congenital anomalies, and developmental milestones.
Children with recurrent ear infections and associated postauricular fistulas.
Document any developmental concerns or associated syndromes.
Performed in cases of chronic infection associated with postauricular fistula.
