About coding Catarrhal congestion
The ICD-10-CM code for Catarrhal congestion is J31.0 (Chronic rhinitis).
Within J31 (chronic rhinitis, nasopharyngitis and pharyngitis), J31.0 is specifically for chronic rhinitis. Related codes cover nasopharyngitis (J31.1) and pharyngitis (J31.2).
Don't report J31.0 together with the conditions in its Excludes1 note: allergic rhinitis (J30.1-J30.9) and vasomotor rhinitis (J30.0).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for J31.0)
