H66.3X2

What This Code Means

This code describes a long-standing infection of the middle ear on the left side that produces pus or discharge, but doesn't fit into the more specific categories of chronic suppurative ear infection. It indicates a chronic condition where the ear drum may have a perforation and fluid continues to drain from the middle ear.

Coding Tips

• •The 'X' in the code is a placeholder and must be filled with the appropriate 5th character; verify documentation specifies 'left ear' (2) versus right ear (1) or bilateral (3)
• •Ensure the condition is documented as 'chronic' and 'suppurative' (draining/purulent) to distinguish from other otitis media types; review imaging or otoscopy notes for confirmation of perforation if present
