About coding nasal mucositis
The ICD-10-CM code for nasal mucositis is J34.81 (Nasal mucositis (ulcerative)).
Within J34.8 (other specified disorders of nose and nasal sinuses), J34.81 is specifically for nasal mucositis (ulcerative). Related codes cover nasal valve collapse (J34.82), odontogenic sinusitis (J34.83) and other specified disorders of nose and nasal sinuses (J34.89).
The conditions in its Excludes2 note aren't part of J34.81, but may be coded alongside it if the patient has both: gastrointestinal mucositis (ulcerative) (K92.81), mucositis (ulcerative) of vagina and vulva (N76.81) and oral mucositis (ulcerative) (K12.3-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
