Acute pansinusitis, unspecified

This diagnosis code signifies an acute inflammatory condition affecting all paranasal sinuses (frontal, maxillary, ethmoid, and sphenoid) simultaneously. It indicates a widespread, sudden onset infection or inflammation of the entire sinus system without further specification of the causative agent.

Use this code when documentation explicitly states "acute pansinusitis" without specifying laterality or the underlying cause (e.g., bacterial, viral, allergic). This is appropriate when the provider has not identified the specific pathogen or etiology.

• Do not use this code if the documentation specifies a chronic pansinusitis; refer to codes in the J32 series.
• If the documentation indicates a specific infectious agent (e.g., streptococcal, viral), use a more specific code from J01.41 or J01.42, or a combination code.
• Always review the medical record for laterality (e.g., right, left, bilateral) or other specific details that would allow for a more precise code selection.
