About coding dust allergy
The ICD-10-CM code for dust allergy is J30.89 (Other allergic rhinitis).
Within J30.8, choose J30.89 (Other allergic rhinitis) only when documentation doesn't support a more specific option: allergic rhinitis due to animal (cat) (dog) hair and dander (J30.81).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 152 (Otitis Media and URI with MCC, relative weight 1.1151) and DRG 153 (Otitis Media and URI without MCC, relative weight 0.7421), in MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
