  • b A diagnosis of OM was assigned using ICD-9-CM codes 381382 in any of the 3 diagnosis fields; 80.4% of OM visits used ICD-9-CM code 382.9 (unspecified otitis media) versus 11.4% for all 381 ICD-9-CM codes (nonsuppurative otitis media and eustachian tube disorders).

  • c Respiratory diagnoses included ICD-9-CM 460–520 (“respiratory” category), as well as mastoiditis (383), allergy (995.3), otitis media (381382), and streptococcal sore throat (034).
