About coding tree allergy
The ICD-10-CM code for tree allergy is J30.1 (Allergic rhinitis due to pollen).
Within J30 (Vasomotor and allergic rhinitis), J30.1 is specifically for allergic rhinitis due to pollen. Related codes cover Vasomotor rhinitis (J30.0), other seasonal allergic rhinitis (J30.2), allergic rhinitis due to food (J30.5), other allergic rhinitis (J30.8) and allergic rhinitis, unspecified (J30.9).
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.
