About coding Strep throat
The ICD-10-CM code for Strep throat is J02.0 (Streptococcal pharyngitis). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J02.0.
Within J02 (acute pharyngitis), J02.0 is specifically for streptococcal pharyngitis. Related codes cover due to other specified organisms (J02.8) and unspecified (J02.9).
The conditions in its Excludes2 note aren't part of J02.0, but may be coded alongside it if the patient has both: scarlet fever (A38.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
