Two SNOMED CT Subsets Released

Two SNOMED CT Subsets Released. NLM Tech Bull. 2015 Sep-Oct;(406):b3.

September 23, 2015 [posted]

NLM is pleased to announce the availability of two SNOMED CT subsets:


  1. A new Convergent Medical Terminology (CMT) subset called Radiology 1 Procedure Subset is now available for download. This file contains 408 concepts which Kaiser Permanente uses to place Radiology orders. The release also includes mappings to Current Procedural Terminology (CPT) and is based on the January 2014 International Release of SNOMED CT.

  2. The SNOMED CT Route of Administration (ROA) subset is a listing of the current set of terms related to the location of administration for clinical therapies. The purpose of the ROA release file is to define a SNOMED CT subset which can be used in the Drug Listings section of the Structured Product Labeling (SPL), or for documentation and encoding of clinical information regarding substance administration. This updated subset is derived from the September 2015 US Edition of SNOMED CT and includes three new concepts.
