Acute sinusitis, unspecified

This code signifies an acute inflammation of the paranasal sinuses where the specific sinus(es) affected are not documented. It indicates a sudden onset of symptoms such as facial pain, pressure, nasal congestion, and discharge, without further anatomical detail.

Use this code when the medical record clearly states "acute sinusitis" but does not specify which sinus (e.g., maxillary, frontal, ethmoid, sphenoid) is involved. It is appropriate when the provider's documentation lacks the specificity to assign a more detailed code for acute sinusitis.

• Avoid using this code if the documentation specifies the affected sinus(es); instead, select the more specific code.
• Query the provider for greater specificity if possible, as more detailed codes offer better data for quality metrics and reimbursement.
• This code should not be used for chronic sinusitis; refer to codes in the J32 series for chronic conditions.
