About coding dander allergy
The ICD-10-CM code for dander allergy is J30.81 (Allergic rhinitis due to animal (cat) (dog) hair and dander).
Within J30.8 (other allergic rhinitis), J30.81 is specifically for allergic rhinitis due to animal (cat) (dog) hair and dander. Related codes cover other allergic rhinitis (J30.89).
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.
