NHS dictionary of medicines and devices (dm+d)

The NHS dictionary of medicines and devices (dm+d) is a dictionary containing unique identifiers and associated textual descriptions for medicines and medical devices. It has been developed for use throughout the NHS as a means of uniquely identifying the specific medicines and devices used in the diagnosis and treatment of PATIENTS.

Data within dm+d is also used to populate the UK Drug Extension; the drug extension then includes relationships into the full UK Edition of SNOMED CT® to items such as products and substances. Further details on these two products can be found on the NHS England website at: Terminology and Classifications.

The codes used to identify dm+d concepts are of the same form as those used in SNOMED CT® and thus conform to the same specification.
