Hello Jordan, Hanzhang, and all,

Thank you for your interest in CPT and BioPortal. We have created a blog post that fully describes the reason for the elimination of CPT, current status of the change, and possible approaches to work with CPT directly. You can find it at

We hope you are able to successfully adapt to the new challenges of CPT access. We welcome further ideas for dealing with this, you are welcome to contact me directly with suggestions.

To whom it may concern,

Hope you are staying well and healthy. I am wiring to you for a question about the UMLS 2020 AA release statement. I am a user of Redcap, a software using bio-ontology service, we have CPT code look up function set up for one of our survey and currently it is deactivated. In your statement you wrote:  UMLS 2020AA release into BioPortal which will be completed by Wednesday Sept 30, does it means the service on Redcap for CPT look up will resume or it is permanently terminated? If it is the latter, could you guide us a good alternate for the CPT code lookup in the bio ontology portal? Thank you.
