Is it Crohn's or something else?

A patient presents to the hospital. You look at a list of ICD-9 codes provided by his Primary Care Physician. The list includes the following:

555.9 Regional enteritis, large intestine.

What is that? It's not until you talk with the patient and find out that, indeed, the patient has Crohn's disease. In fact, not only does he have Crohn's disease, you discover that he also has an abscess associated with it. In ICD-10, the code will be:

K50.114 Crohn's disease of large intestine with abscess

Wouldn't that be a much better description of this patient? In one phrase, you were able to accurately describe what the patient has and include a medical complication that better represents his severity of illness.

If somebody later on analyzes the data, they'd realize that this is no ordinary Crohn's patient you're taking care of.  Risk adjustments are made to  account for utilization and quality measurements.

Next week, we'll talk about APR-DRG, a system that classifies people into risks of mortality and severity of illness.
