Other polyp of sinus

This code signifies the presence of a benign growth, specifically a polyp, within any of the paranasal sinuses other than those specifically classified elsewhere. These polyps are typically non-cancerous and can cause symptoms like nasal obstruction, discharge, or facial pain.

Use this code for documented cases of sinus polyps when the specific sinus involved is not identified, or when the polyp is located in a sinus not covered by more specific ICD-9 codes. Documentation should clearly state "sinus polyp" without further anatomical specificity, or specify a sinus not otherwise categorized (e.g., sphenoid sinus polyp).

• Do not use this code if the polyp is explicitly documented as originating from the nasal cavity (use 471.0) or antrochoanal (use 471.1).
• Always seek further specificity from the provider if the documentation is vague regarding the exact sinus involved, to ensure the most precise code is assigned.
• Consider sequencing this code after any codes for associated conditions, such as chronic sinusitis, if applicable.
