Benign neoplasm of other parts of oropharynx

This code signifies the presence of a non-cancerous growth or tumor located in various regions of the oropharynx, excluding the tonsils, adenoids, and soft palate. These benign neoplasms are typically slow-growing and do not metastasize, but may cause symptoms such as dysphagia, odynophagia, or a palpable mass depending on their size and location.

Assign this code when documentation clearly identifies a benign neoplasm within the oropharynx, specifically in areas like the posterior pharyngeal wall, lateral pharyngeal wall, or base of tongue (excluding tonsillar tissue). Supporting documentation should include pathology reports confirming benignity and a precise anatomical location within the oropharynx.

• Ensure the pathology report explicitly states "benign" to differentiate from malignant or uncertain behavior neoplasms.
• Verify the exact anatomical site within the oropharynx; if the neoplasm is of the tonsil, soft palate, or adenoids, a more specific code will be required.
• Do not use this code for inflammatory lesions or cysts; these have distinct ICD-9-CM codes.
