J39.8Other specified diseases of upper respiratory tract

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

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 202 (Bronchitis and Asthma with CC/MCC, relative weight 0.9474) and DRG 203 (Bronchitis and Asthma without CC/MCC, relative weight 0.6512), in Pre-MDC and MDC 04 (Diseases and Disorders of the Respiratory System), 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 478.9 (other and unspecified diseases of upper respiratory tract) and 519.19 (other diseases of trachea and bronchus).
