Radicular cyst
ICD-10 K04.8 is a billable code used to indicate a diagnosis of radicular cyst.
A radicular cyst is a type of odontogenic cyst that arises from the epithelial remnants of the dental lamina or from the inflammation of the pulp tissue. Clinically, it often presents as a painless swelling in the jaw, typically associated with a non-vital tooth. The cyst is usually located at the apex of a tooth root and can lead to bone resorption if left untreated. The anatomy involved includes the maxilla or mandible, where the cyst can cause displacement of teeth and may be detected through radiographic imaging as a well-defined radiolucency. Disease progression can lead to complications such as infection or tooth loss if the cyst becomes large or symptomatic. Diagnostic considerations include clinical examination, radiographic evaluation, and histopathological analysis following surgical intervention. Treatment typically involves enucleation of the cyst and management of the associated dental issues, such as root canal therapy or extraction of the affected tooth.

K04.8 specifically covers radicular cysts, which are associated with non-vital teeth and arise from periapical inflammation. It does not cover other types of odontogenic cysts or lesions.
K04.8 should be used when a radicular cyst is diagnosed, particularly when it is confirmed through imaging and clinical examination, differentiating it from other periapical conditions like abscesses or granulomas.
Documentation should include clinical findings, radiographic evidence of the cyst, treatment notes, and any histopathological reports confirming the diagnosis post-surgery.
