Acute suppr otitis media w spon rupt ear drum, unsp ear

This diagnosis code signifies an acute bacterial infection of the middle ear, characterized by pus formation and a spontaneous perforation of the tympanic membrane. The infection is acute, meaning it has a rapid onset and short duration, and the specific ear affected is not documented.

This code is appropriate when the physician's documentation explicitly states acute suppurative otitis media with a spontaneous rupture of the eardrum, and the laterality (left or right ear) is not specified. It is used when the patient presents with symptoms such as otalgia, fever, and otorrhea, and examination confirms a perforated tympanic membrane due to the infection.

• Only use this code when laterality is truly unspecified; otherwise, use the more specific codes for left (H66.012) or right (H66.011) ear.
• Distinguish from chronic otitis media or traumatic rupture of the eardrum, which have different code assignments.
• Ensure documentation clearly indicates "spontaneous rupture" versus a myringotomy or other iatrogenic perforation.
