Acute mastoiditis with other complications, right ear

This code signifies an acute inflammatory process of the mastoid air cells in the right ear, accompanied by complications beyond simple inflammation, such as facial nerve paralysis, labyrinthitis, or intracranial extension. It indicates a more severe presentation of mastoiditis requiring specific clinical attention.

Use this code when documentation clearly states acute mastoiditis affecting the right ear, along with a specified complication other than an abscess. Supporting documentation should detail the acute nature of the infection, its location, and the specific "other" complication identified by the physician.

• Ensure the documentation specifies "acute" mastoiditis and identifies the right ear.
• Distinguish "other complications" from mastoiditis with subperiosteal abscess (H70.01-) or intracranial complications (H70.02-).
• Always code the specific complication if a more precise ICD-10-CM code exists, in addition to this code, if applicable and supported by documentation.
