Other cysts of jaws

This code represents non-odontogenic cysts of the jawbones, excluding those specifically classified elsewhere (e.g., dentigerous, radicular, or primordial cysts). These are typically benign, fluid-filled sacs that develop within the maxilla or mandible, often discovered incidentally on imaging or due to swelling.

Apply this code for documented diagnoses of jaw cysts that are not clearly identified as odontogenic or are described as "other" or "unspecified" non-odontogenic cysts. Supporting documentation would include pathology reports confirming a non-odontogenic cyst or imaging reports describing a jaw cyst without further specific classification.

• Do not use for odontogenic cysts; these have more specific codes within the 526 series.
• Ensure documentation clearly states the cyst is of the jaw and is not a specific type with its own code.
• Consider laterality if specified in the documentation, though this code does not differentiate.
