Acute recurrent pansinusitis

This code signifies an acute inflammatory condition affecting all paranasal sinuses (frontal, ethmoid, sphenoid, and maxillary) that recurs after a period of resolution. It indicates a flare-up of widespread sinus inflammation following a previous episode.

Use this code when documentation clearly states "acute recurrent pansinusitis" or describes an acute exacerbation of inflammation involving all sinuses in a patient with a history of prior, similar episodes. Supporting documentation should detail the acute nature of the current episode and the involvement of all sinus cavities.

• Ensure documentation specifies "recurrent" to differentiate from a single acute episode.
• Do not confuse with chronic pansinusitis (J32.4), which implies persistent inflammation rather than distinct acute episodes.
• Look for specific mention of all four sinus groups (frontal, ethmoid, sphenoid, maxillary) being affected to justify "pansinusitis."
