Acute recurrent frontal sinusitis

This code signifies an acute inflammatory process affecting the frontal sinuses that recurs after a period of resolution. It indicates a pattern of repeated, short-term episodes of frontal sinus infection rather than a chronic, persistent condition.

Apply this code when documentation clearly states "acute recurrent frontal sinusitis" or describes multiple distinct episodes of acute frontal sinusitis in a patient. Ensure the medical record differentiates these acute recurrences from a single prolonged acute episode or chronic sinusitis.

• Differentiate from J32.1 (Chronic frontal sinusitis) which implies persistent inflammation lasting 12 weeks or more.
• Do not use for a single, initial episode of acute frontal sinusitis (J01.10).
• Look for specific physician documentation of "recurrent" or "multiple episodes" of acute frontal sinusitis.
