Other acute recurrent sinusitis

This code signifies an acute inflammation of the paranasal sinuses that recurs after a period of resolution, but does not meet the criteria for chronic sinusitis. It indicates that the patient experiences repeated episodes of acute sinusitis, affecting multiple or unspecified sinuses, or a specific sinus not otherwise classified.

Apply this code when documentation clearly states "recurrent acute sinusitis" or "acute recurrent sinusitis" and specifies that the condition is not chronic. This code is appropriate for patients experiencing distinct, separate episodes of acute sinusitis that resolve between occurrences. Ensure the medical record differentiates between acute, recurrent acute, and chronic sinusitis.

• Do not use this code for a single episode of acute sinusitis; use the appropriate J01.x0 code.
• Distinguish carefully from chronic sinusitis (J32.x), which implies persistent inflammation for 12 weeks or more.
• If the specific sinus affected is documented (e.g., frontal, maxillary), use the more specific recurrent acute sinusitis code (e.g., J01.11, J01.21).
