Rapid responses are electronic letters to the editor. They enable our users to debate issues raised in articles published on thebmj.com. Although a selection of rapid responses will be included online and in print as readers' letters, their first appearance online means that they are published articles. If you need the url (web address) of an individual response, perhaps for citation purposes, simply click on the response headline and copy the url from the browser window. Letters are indexed in PubMed.
We were delighted to see our recent study on Type 3c diabetes listed in BMJ news section. Since highlighting that the majority of cases of type 3c diabetes are misclassified (and recorded) as type 2 diabetes in UK primary care (1), we have been asked, by colleagues, to provide our recommendations for how type 3c should be coded. The correct identification and recording of this diabetes sub-type is vital to ensuring these patients get tailored diabetes management. This includes considering pancreatic enzyme replacement, osteoporosis, fat soluble vitamin deficiency, and early use of insulin.
There is currently no code in use in UK primary care which uses the nomenclature 'type 3c' diabetes. We therefore recommend the use of the following codes to clearly label this type of diabetes.
Read Version 2:
• C10G. Secondary pancreatic diabetes mellitus
• X40JB Secondary pancreatic diabetes mellitus
• SCTID: 51002006 Diabetes mellitus associated with pancreatic disease (disorder)
The use of these codes ensures that patients will remain on the QoF diabetes registers and therefore be flagged for appropriate diabetes reviews and monitoring. We know that people with diabetes recorded using codes outside this recall system get worse care (2).
