Additional Info

  • The "NOS" here refers to the fact that it's not clear if the pneumothorax is tension or non-tension
  • Does NOT include traumatic.
  • For iatrogenic pneumothorax, see guideline below
  • This code includes a nontraumatic bronchopleural fistula where it's not clear if the pneumothorax is with or without tension. When these fistulas are spontaneous (rather than caused iatrogenically or by trauma), it is due to lung infection or abscess, then that code should also be combined with the appropriate one of these. And in this case also code Empyema (pyothorax) if present, combining it with the others.
