Other cysts of jaw

This code signifies the presence of a non-odontogenic or non-developmental cyst located within the jawbone, excluding those specifically classified elsewhere. These are fluid-filled sacs that can develop in the maxilla or mandible, often discovered incidentally on imaging or due to localized swelling or pain.

Apply this code when documentation specifies a jaw cyst that does not originate from tooth-forming tissues (odontogenic) and is not a recognized developmental cyst with a more specific ICD-10-CM code. This is appropriate for conditions like aneurysmal bone cysts, simple bone cysts, or other unclassified jaw cysts.

• Ensure the documentation explicitly rules out odontogenic or specific developmental cysts.
• Do not use this code if a more specific ICD-10-CM code for a jaw cyst (e.g., M27.0, M27.2) is available.
• Code any associated symptoms (e.g., pain, swelling) or complications (e.g., infection) separately.
