Does anyone have a good resource for understanding the relationship between readmission for complications and the global surgical period? For example, if a patient had a procedure with a 090 global period and developed a bloodstream infection (R78.81) on day 30 that could be documented as directly related to the procedure: does that change the DRG to a DRG with CC (assuming no exclusion)? would it the cost of treating the CC be considered part of the global period and not paid separately (patient is readmitted to hospital for medical but no O.R. procedure needed)? thank you.
