Dual Coding & ICD-10 Transition

ICD-10 implementation is looming, and the industry is scrambling to prepare for the transition. Our post in May gives a broad overview of ICD-10 and how to prepare, but let’s talk now more specifically about “Dual Coding.”

What is “Dual Coding?”

Dual Coding is the term that describes claims that have both ICD-9 and ICD-10 diagnosis codes. When a major change occurs, there is usually some leeway in the first few months that would allow for this type of claim to squeak through. This gives time for all players to get acclimated to the new requirements and how to implement them. Dual Coding has been a hot topic of sorts in our industry, with many wondering if it would be allowed.  With this release from Medicare, that question has been largely answered with a resounding “NO.” All claims after October 1, 2014 will be denied if they contain ICD-9 diagnosis codes. Private insurers are sure to follow suit.

What Can You Do?

Prepare! Medicare shows no indication of delaying the transition, and is pushing for quick and relatively painless transition. Rather than allowing for acclimation in the first few months, your practice will need to be prepared PRIOR to the transition date. October 1, 2014 may seem like a long way off, but this transition will require a complete overhaul of many office processes. Do not let your practice’s cash flow be affected by needless denials!

    I think you should host a seminar regarding ICD-10 so we office gals can learn how to use the new book.

      Great idea! I will definitely be in each client’s office for training as we get into 2014.
