Here is an example of a specific documentation gap we’ve identified related to respiratory failure which is classified more specifically In ICD-10-CM than in ICD-9-CM. The respiratory failure codes in ICD-10-CM have been expanded to include codes for acute, chronic, acute on chronic, and unspecified types of respiratory failure at the 4^th digit level. And they’re also further subdivided as to whether or not the respiratory failure is associated with hypoxia, with hypercapnea, or unspecified whether with hypoxia or hypercapnea.
