Benign neoplasm of tonsil

This code identifies a non-cancerous growth originating from the palatine tonsils. These benign neoplasms are typically slow-growing and do not metastasize, but they can cause symptoms such as dysphagia, foreign body sensation, or recurrent tonsillitis depending on their size and location. Histologically, they may include papillomas, fibromas, or lipomas.

Use this code when documentation clearly states a benign neoplasm of the tonsil (referring specifically to the palatine tonsils). This diagnosis is often established after biopsy or surgical excision and subsequent pathological review. Clinical notes indicating a non-malignant growth on the tonsil, without further specification of lingual or pharyngeal tonsil, would also support its use.

• Carefully distinguish between benign neoplasms of the palatine tonsil versus the lingual or pharyngeal tonsils, as these have distinct codes.
• Ensure the documentation confirms the benign nature of the growth; if malignancy is suspected or confirmed, a C-code would be appropriate.
• Do not use this code for benign neoplasms of the tonsillar fossa or tonsillar pillars, which are coded to D10.5.
