About coding Scratchy throat
The ICD-10-CM code for Scratchy throat is R09.89 (Other specified symptoms and signs involving the circulatory and respiratory systems).
Within R09.8, choose R09.89 (Other specified symptoms and signs involving the circulatory and respiratory systems) only when documentation doesn't support a more specific option: nasal congestion (R09.81) and Postnasal drip (R09.82).
The conditions in its Excludes2 note aren't part of R09.89, but may be coded alongside it if the patient has both: foreign body in throat (T17.2-) and wheezing (R06.2).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
