Sialolithiasis

This code represents the presence of salivary gland stones, also known as sialoliths, which are calcified masses that form within the salivary ducts or glands. These stones can obstruct the flow of saliva, leading to pain, swelling, and inflammation of the affected gland.

Use this code for patients diagnosed with salivary gland calculi, typically presenting with symptoms such as acute or chronic swelling, pain, or infection of a major salivary gland (e.g., submandibular, parotid). Documentation should clearly indicate the presence of a stone, often confirmed by imaging studies like ultrasound or CT scan, or direct visualization.

• Differentiate from other salivary gland disorders like sialadenitis without stone formation (527.2) or salivary gland fistula (527.4).
• Specify the affected gland if known and documented, though this code is general for any location.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity impacting treatment.
