Q&A: How to resolve DRG confusion

Q: Confession. I am very frustrated. I am fairly new to CDI. I have a nursing background. I’m trying to understand how

Learning how to navigate the coding and DRG landscape can be daunting. Don't worry. Others have had to learn this too. Ask for help and know you are in good company.

the coding and DRG system works. But when I look up a diagnosis in the DRG Expert in the alphabetic index to diseases it is not listed as I would expect it to be.

Take for example, bradycardia. It is not listed under that term or arrhythmia.  Yet, it is listed under cardiac arrhythmia. For another example, how about anorexia? The only listing is anorexia nervosa—not unspecified.

I also find it ironic that I cannot infer what a physician is stating (it has to be documented precisely) but when I have to look up a term I have to guess its meaning.

Do you have any advice for me?

A: Your frustration is very common among new clinical documentation improvement (CDI) specialists.  The publishers of the DRG Expert did not include the same type of Index to Diseases that you would find in Volume I of an ICD-9 code book—probably to save space. The Index to Diseases alone in my code book is 380+ pages.

This is one reason that during the CDI BootCamp I mention so many diagnoses as we review Medicare Severity Diagnosis-related groups (MS-DRGs) in a major diagnostic category (MDC) and either have you highlight them or write them in, because I, too, had exactly the same issues you are having.

Every CDI team should also have a coding book in their department to use as a reference (ask your facility HIM department if they have an old one you can have), especially if you do not have access to the encoder (coding and reimbursement software), which would let you look up whatever you wanted—however, even that has limitations, because search terms often use “coding language” rather than the everyday language of clinicians.

As far as your comment regarding the irony of the situation, all I can say is “Right on, girl!”  It is the reason we have taken on this role. We were hired to become the “translators” or “interpreters” to ensure that the clinical language matches the language needed by the coders. Acquiring the skills to understand both of these languages, along with the ability to translate from one to the other, is what makes us, as CDI professionals, unique.

As a final note, I just want to share that my very first DRG Expert was COVERED from end to end with handwritten notes, stickies, and slips of paper. I used this book for three years, copying my info into each new edition until I was granted encoder access. Every time I asked a coder where to find something I wrote it in the book—especially those diagnoses that had really strange “code” descriptions.

I hope that I can assure you, that by this time next year, you will have many of these coding terms memorized.

I tell all my CDI BootCamp students that there is a long learning curve to this position, so don’t worry. While some people catch on quickly, for most it may take up to six months before that proverbial light bulb finally goes on and frequently it takes up to a year to feel confident in the role.

Don’t get discouraged. Most CDI specialists will tell you the same thing! Before you know it, you will find yourself sitting in traffic, converting license plate numbers into DRGs or diagnosis codes.
