Recently, we received the following question regarding the rules related to diabetes coding:
We have restarted our physician inservices on HCC and I need clarification on
the plan's view of using the term "with" in relation to DM complications. Is it
appropriate for providers to document "Diabetes with renal disease" in their
progress notes and code 250.40?
Thanks for your feedback!
This is a very difficult question, mostly because a lot of rumors are floating around. We’re hearing on industry calls that there is an absolute change in diabetes coding and that the term “with” now supports a diabetic complication in all cases. We’re also hearing that “someone” from Coding Clinic or AHIMA (which has no authority regarding ICD-9 coding) or CMS has confirmed this AND that it is retroactive. Unfortunately, the “someone” is always unnamed. No health plan has the authority to make rulings on ICD-9 use, that authority rests with Coding Clinic when the Official Coding Guidelines are silent. In this situation, it is important to deal only with the facts.
What is fact is that there is a recent Coding Clinic on Diabetes “with” neuropathy. Basically, the question posed was if the documentation indicates “diabetes with neuropathy”, can it be assumed that the neuropathy is secondary to the diabetes. The answer was yes…but Coding Clinic went on to give a reason, which may be very important. The reason given was that neuropathy secondary to diabetes is so common that the assumption could be made.
This seems very different than “diabetes with CKD”, for example. The National Kidney Foundation doesn’t assume a relationship between diabetes and CKD unless certain conditions exist…eg, diabetic retinopathy, etc. Also, unlike most situations where Coding Clinic has done a complete about face from earlier instructions, there is no acknowledgement that this represents a change in a longstanding rule. Nor does Coding Clinic speak to assuming a causal relationship with any other complication.
We are extremely concerned that these rumors will lead to physicians documenting in a way that CMS will not accept.
We have contacted the CMS and asked them to speak to these issues. CMS has said that they do not know, but will look into this issue.
We believe that if there had already been official confirmation that this ruling applied to all “diabetes with _________” situations, and made it retroactive, CMS staff would have a definitive answer. Since they haven’t given us a definitive answer, we don’t believe it is safe to ignore the previous advice that physician must state a causal relationship just yet. Their lack of definitive response only reinforces our belief that physicians need to be cautious and not accept these rumors as fact.
We will continue to monitor this situation, and await CMS’ response. We’ll post that information here on HCC University as soon as it becomes available.
