Notes

Also from chapter/block level (1 note)
Inherited from Chapter 10 Diseases of the respiratory system
  • When a respiratory condition is described as occurring in more than one site and is not specifically indexed, it should be classified to the lower anatomic site (e.g. tracheobronchitis to bronchitis in J40).
