About coding pneumothorax tension
The ICD-10-CM code for pneumothorax tension is J93.0 (Spontaneous tension pneumothorax).
Within J93 (pneumothorax and air leak), J93.0 is specifically for spontaneous tension pneumothorax. Related codes cover other spontaneous pneumothorax (J93.1), other pneumothorax and air leak (J93.8) and pneumothorax, unspecified (J93.9).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" 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 199 (Pneumothorax with MCC, relative weight 1.7322), DRG 200 (Pneumothorax with CC, relative weight 1.0774) and DRG 201 (Pneumothorax without CC/MCC, relative weight 0.6782), in 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.
