Question:
I would like to know what surgery CPT code 43847 applies to, lap RYN or BPDDS.

I am a bit confused. My insurance approved me for RYN Gastrojejunostomy (CPT Code 43847). But upon further research, that code seems to apply to the RNY and the BPDDS. I would like to know for sure which surgery I have been approved for. I am having my surgery at The Bariatric Center of Penn. Thank you for any information.    — Stephanie W.

These are all CPT Codes: 43842=Gastric restrictive procedure without gastric bypass for morbid obesity; vertical-banded gastroplasty 43843= Other than vertical-banded gastroplasty 43846= Gastric restrictive procedure,with gastric bypass for morbid obesity; with short limb (less than 100 cm) Roux-en-Y gastroenterostomy 43847= With small intestine reconstruction to limit absorption 43848= Revision of gastric restrictive procedure for morbid obesity (seperate procedure) 43850= Revision of gastriduodenal anastomosis (gastroduodenostomy) with reconstruction, without vagotomy 43855=with vagotomy 43860= Revision of gastrojejunal anastomosis (gastrojejunostomy) with reconstruction, with or without partial gastrectomy or intestine resection; without vagotomy 43865= with vagotomy Hope this list of CPT codes helps you figure out what on your insurance company will cover....If not...call the doctor to see what procedure code they will be using to code your operation to see if it will be covered....Hope this is useful information to you..Christine

As I understand it, as of January 1, 2005, the duodenal switch will get a new code -- see my posting from October 26th: <P> New CPT Codes for DS in 2005<P> I'm posting this to further respond to a recent question here -- this is from one of the Rabkins' patients, who I believe is in the insurance biz -- I have no idea what it means in real life, but if you are submitting for surgery in the coming weeks, you might want to make sure your surgeon uses this new CPT code as well: <P> The CPT 2005 code book has the following Category I code assignment on page 178: <P> 43845 Gastric restrictive procedure with partial gastrectomy, pylorus-preserving duodenalileostomy and ileoileostomy (50 to 100 cm common channel) to limit absorption. (biliopancreatic diversion with duodenal switch) <P> I could find no entry describing a lap DS explicitly, although the RNYGB was assigned one for lap. The code becomes effective on January 1, 2005; insurers are given information regarding changes and additions to the code book a few weeks before it gets published, so insurers already know the DS has its very own code now. I just got my book today, so you can figure they've known about it since the first week in October at least. <P> ALSO: The code newly assigned for the duodenal switch (43845) is NOT a category II or III code (the not ready for prime time categories); there was some concern last February that the editorial board would assign the DS its own single code but put it in the II or III categories. As category II and III are used to track the soundness of procedures or gather more datat on procedures, I infer the assignment of a category I code indicates the DS procedure has been adequately studied to be put into general use. The new code will become effective January 1, 2005. The insurance companies were informed of new codes several weeks ago in order to give them time to be ready to implement the new data on the first of the new year. (As a cynical soul, I grumble that the extra time is given so they can formulate new reasons for not covering a procedure -- grrrrrrrrr.) The stance of the AMA on giving codes to procedures is that the code assignment signifies "Inclusion of a descriptor and its associated five-digit number in the CPT book is based on whether the procedure is consistent with contemporary medical practice and is performed by many practitioners in clinical practice in multiple locations." Code assignment, of course, does not equal AMA endorsement. <P> The standard RNYGB (code 43846) was given a new code for when it is performed laparoscopically -- 43644 -- but I could not find a lap code specifically for the DS.
