ICD-10 code for bronchus congenital diverticulum

The ICD-10-CM code for bronchus congenital diverticulum is Q32.4 (Other congenital malformations of bronchus). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q32.4.

Within Q32, choose Q32.4 (Other congenital malformations of bronchus) only when documentation doesn't support a more specific option: congenital tracheomalacia (Q32.0), other congenital malformations of trachea (Q32.1), congenital bronchomalacia (Q32.2) and congenital stenosis of bronchus (Q32.3).

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 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.
