About J31.0

J31.0 is the ICD-10-CM diagnosis code for chronic rhinitis. It belongs to category J31 (chronic rhinitis, nasopharyngitis and pharyngitis), 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 J31 (chronic rhinitis, nasopharyngitis and pharyngitis), J31.0 is specifically for chronic rhinitis. Related codes cover nasopharyngitis (J31.1) and pharyngitis (J31.2).

Don't report J31.0 together with the conditions in its Excludes1 note: allergic rhinitis (J30.1-J30.9) and vasomotor rhinitis (J30.0).

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 472.0 (chronic rhinitis).
