Mucocele of salivary gland

This code represents a benign, fluid-filled cyst that forms due to a blockage or trauma to a salivary gland duct, most commonly affecting the minor salivary glands of the lower lip. It results from the extravasation of mucus into the surrounding connective tissue, creating a soft, often bluish, swelling.

Use this code for documented cases of a mucocele affecting any salivary gland, such as a ranula (mucocele of the sublingual gland) or a mucocele of the minor salivary glands. Documentation should clearly indicate the presence of a mucocele and its salivary gland origin.

• Differentiate from other oral lesions like fibromas or papillomas, which have different etiologies and histological features.
• Ensure the documentation specifies "mucocele" and not just a generic "cyst" of the oral cavity.
• Consider additional codes for any associated trauma if it is the documented cause of the mucocele.
