About J39.2

J39.2 is the ICD-10-CM diagnosis code for other diseases of pharynx. It belongs to category J39 (other diseases of upper respiratory tract), 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 J39, choose J39.2 (Other diseases of pharynx) only when documentation doesn't support a more specific option: Retropharyngeal and parapharyngeal abscess (J39.0), other abscess of pharynx (J39.1), upper respiratory tract hypersensitivity reaction, site unspecified (J39.3), other specified diseases of upper respiratory tract (J39.8) and disease of upper respiratory tract, unspecified (J39.9).

The conditions in its Excludes2 note aren't part of J39.2, but may be coded alongside it if the patient has both: chronic pharyngitis (J31.2) and ulcerative pharyngitis (J02.9).

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 011 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC, relative weight 5.6154), DRG 012 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CC, relative weight 4.381), DRG 013 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCC, relative weight 2.7307), DRG 154 (Other Ear, Nose, Mouth and Throat Diagnoses with MCC, relative weight 1.5921), DRG 155 (Other Ear, Nose, Mouth and Throat Diagnoses with CC, relative weight 0.9322) and DRG 156 (Other Ear, Nose, Mouth and Throat Diagnoses without CC/MCC, relative weight 0.6659), in Pre-MDC and 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 478.25 (edema of pharynx or nasopharynx), 478.26 (cyst of pharynx or nasopharynx) and 478.29 (other diseases of pharynx, not elsewhere classified).
