About J30.1
J30.1 is the ICD-10-CM diagnosis code for allergic rhinitis due to pollen. It belongs to category J30 (Vasomotor and allergic rhinitis), block J30-J39 (other diseases of upper respiratory tract) and chapter 10 (diseases of the respiratory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
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.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 477.0 (allergic rhinitis due to pollen).
