Cysts of oral soft tissues

This code represents non-neoplastic, fluid-filled sacs or lesions that develop within the soft tissues of the oral cavity, excluding those originating from odontogenic structures. These cysts are typically benign and can arise from various developmental or inflammatory processes affecting the oral mucosa, salivary glands, or other soft tissue components.

Use this code for diagnoses such as mucocele, ranula, or epidermoid/dermoid cysts of the oral soft tissues. Documentation should clearly specify the presence of a cyst and its location within the oral soft tissues, distinguishing it from odontogenic cysts or other oral lesions.

• Differentiate carefully from odontogenic cysts (e.g., radicular, dentigerous), which have specific codes within the 526 series.
• Avoid using this code for inflammatory lesions or benign neoplasms that are not true cysts.
• Ensure documentation specifies the type of cyst if known (e.g., mucocele) to support the most accurate diagnosis.
