Elizabeth is seen for acute ear pain. Examination reveals left acute serous otitis
media. Further examination revealed a total perforated tympanic membrane of the
right ear due to chronic otitis media. What diagnoses codes are assigned?
Answer:
H65.02 Otitis (acute), media (hemorrhagic) (staphylococcal) (streptococcal)
acute, subacute, serous – see Otitis, media, nonsuppurative, acute, serous. Otitis
media, nonsuppurative, acute or subacute, serous
H66.91 Otitis (acute), media (hemorrhagic) (staphylococcal) (streptococcal),
chronic
H72.821 Perforation, perforated (non-traumatic) (of), tympanum, tympanic
(membrane) (persistent post-traumatic) (post-inflammatory), total
Rationale: Otitis media has an expansion of codes in ICD-10-CM to classify
these conditions. Laterality is also part of the classification in ICD-10-CM. In
category H65, distinction is made between recurrent infections. A note is present
stating that an additional code for any associated perforated tympanic membrane
should be coded separately. It is then possible to show which tympanic membrane
is perforated by assigning the correct code for right side associated with the
chronic otitis media. Otitis media refers to inflammation of the middle ear (area
between ear drum and inner ear including the eustachian tube). Serous otitis
involves a collection of fluid that occurs in the middle ear space caused by altered
eustachian tube function. This is also referred to as secretory or with effusion.
