About coding allergic rhinitis
The ICD-10-CM code for allergic rhinitis is J30.9 (Allergic rhinitis, unspecified). The official index lists 6 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J30.9.
It is also searched as hay fever, seasonal allergies.
Within J30, choose J30.9 (Allergic rhinitis, unspecified) only when documentation doesn't support a more specific option: Vasomotor rhinitis (J30.0), allergic rhinitis due to pollen (J30.1), other seasonal allergic rhinitis (J30.2), allergic rhinitis due to food (J30.5) and other allergic rhinitis (J30.8).
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.
