H66.91
ICD-10-CMThis code signifies inflammation of the middle ear in the right ear, where the specific type or cause of otitis media is not documented. It indicates a general diagnosis of middle ear infection without further detail regarding its nature (e.g., acute, chronic, serous).
Use this code when the medical record clearly states "otitis media, right ear" but lacks further specificity regarding the type or etiology. Documentation supporting its use would include physician notes indicating otitis media in the right ear without additional qualifying terms.
