Gastroenterology Coding Alert

Question: A patient reported to the office for a colonoscopy, during which the gastroenterologist used India ink to mark two lesions she removed by snare technique. I have heard stories about gastroenterology offices getting reimbursed for India ink tattooing, but I'm skeptical. Should I report the tattooing, or just stick with the base colonoscopy?

Montana Subscriber Answer: It depends on whom you are reporting to. Though it is undeniably valuable to the patients who need it, Medicare does not reimburse specifically for India ink tattooing. To further complicate things, there is also no specific CPT code for the procedure, leaving coders with few choices if they want reimbursement for India ink.
 
But there is a code for colonoscopy with injection - and this could be your ticket to India ink payment.
 
For the colonoscopy and the India ink tattooing, report only one code: 45381 (Colonoscopy, flexible, proximal to  splenic flexure; with directed submucosal injection[s], any substance).
 
According to the National Correct Coding Initiative rules, 45381 is not bundled into any other colonoscopy code, so it can be billed without a modifier.
 
Medicare should reimburse for the additional injection service above the base colonoscopy code. But some commercial carriers may deny the additional service and claim that it is included in the higher-valued code.
 
You may also have to appeal a denied claim in order to receive full payment for a colonoscopy with India ink tattooing, at least initially. If you file an appeal, make sure to include a separate letter containing cost estimates of the procedure, including materials and supplies used and the additional nursing time required, if any.
 
An appeal takes a lot of time, but if you do it properly and the payer recognizes India ink tattooing once, it is more likely to accept future tattooing claims on good faith.  Of course, if a payer has laid out its reasons for not reimbursing India ink tattooing, stop coding for the procedure with that payer, unless you want auditors in your office.
