On November 9, 2010, the National Library of Medicine announced a free service that allows electronic health records (HER) systems to link users to MedlinePlus. This service is called MedlinePlus Connect.
MedlinePlus Connect accepts requests for information on diagnoses (problem codes) and medications. NLM mapped MedlinePlus health topics to two standard diagnostic coding systems used in EHRs: ICD-9-CM and SNOMED CT CORE. When an EHR submits a request to MedlinePlus Connect, the service returns the closest matching health topic as a result.
MedlinePlus Connect also links EHR systems to drug information written especially for patients. For medication codes, MedlinePlus Connect accepts RXCUIs and NDCs.
