Acute recurrent maxillary sinusitis

This code signifies an acute inflammatory process affecting the maxillary sinus, characterized by repeated episodes. It indicates that the patient experiences recurrent, rather than chronic, acute infections of this specific sinus cavity.

Apply this code when documentation clearly states "acute recurrent maxillary sinusitis" or describes multiple distinct acute episodes of maxillary sinus infection. Supporting documentation should include physician notes detailing the acute nature and recurrence of the condition.

• Differentiate carefully from chronic maxillary sinusitis (J32.0) or unspecified acute sinusitis (J01.90).
• Ensure the documentation specifies "recurrent" and "acute" to justify this specific code.
• Do not use for a single acute episode; recurrence must be explicitly stated or clearly implied by the clinical history.
