What the document contains

The BNF SNOMED Mapping document contains:

  • BNF Code
  • SNOMED code
  • dm+d (dictionary of medicines and devices) description
  • MDR description

 

BNF Code 

This is a 15 digit code in which the first seven digits are allocated according to the categories in the BNF. The last 8 digits represent the medicinal product, form, strength and the link to the generic equivalent product.

NHS Prescription Services has created pseudo BNF chapters which are not published for items not included in BNF chapters 1 to 15. Most of these items are dressings and appliances, which NHS Prescription Services has classified into the pseudo BNF chapters 20 - 23.

 

SNOMED code

This is a universal identifying code unique to a medicinal product.

 

dm+d (dictionary of medicines and devices) description

This contains unique identifiers (codes) and associated textual descriptions for representing medicines and medical devices in information systems and electronic communications.

It has been developed for use throughout the NHS as a way of uniquely identifying the specific medicines and medical devices used in the diagnosis or treatment of patients.

 

MDR description

MDR is the NHSBSA database which holds drug and appliance records. It is used in the processing and reporting of prescription information. These records are organised within the database, using British National Formulary (BNF) codes.
