About coding pharynx necrosis
The ICD-10-CM code for pharynx necrosis is J02.9 (Acute pharyngitis, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on J02.9.
Within J02, choose J02.9 (unspecified) only when documentation doesn't support a more specific option: streptococcal pharyngitis (J02.0) and due to other specified organisms (J02.8).
Don't report J02.9 together with the conditions in its Excludes1 note: influenza virus with other respiratory manifestations (J09.X2, J10.1, J11.1).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
