ICD-10 code for Fauces abscess

The ICD-10-CM code for Fauces abscess is J39.1 (Other abscess of pharynx).

Within J39, choose J39.1 (Other abscess of pharynx) only when documentation doesn't support a more specific option: Retropharyngeal and parapharyngeal abscess (J39.0), other diseases of pharynx (J39.2), 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).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

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 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 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.
