About coding throat catarrh
The ICD-10-CM code for throat catarrh is J31.2 (Chronic pharyngitis).
Within J31 (chronic rhinitis, nasopharyngitis and pharyngitis), J31.2 is specifically for chronic pharyngitis. Related codes cover rhinitis (J31.0) and nasopharyngitis (J31.1).
The conditions in its Excludes2 note aren't part of J31.2, but may be coded alongside it if the patient has both: acute pharyngitis (J02.9).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
