I am working with the ‘CanMED: Cancer Medications Enquiry Database’ from the NCI/SEER Observational Research in Oncology Toolbox (see here https://seer.cancer.gov/oncologytoolbox/) in hopes that it can be used for the vocabulary portion of the Oncology Treatment Proposal (see here: https://github.com/OHDSI/CommonDataModel/issues/163). CANMed classifies low-level NDC/HCPCS codes to higher-level concepts: ‘Minor Class’, ‘Major Class’ and a ‘SEERRx Category’. Importantly, CanMED’s highest level classification, the 'SEERRx Category’, can be mapped to NAACCR/SEER data items. This could be the basis for the ability to crosswalk between EHR oncology treatment data and tumor registry oncology treatment data.
As part of my analysis of CanMED I want to map its NDC/HCPCS codes to RxNorm codes. I am using the OMOP vocabulary to achieve the mappings to RxNorm. I have found some missing codes and mappings within the OMOP vocabulary.
And regarding missing concepts: please send us codes, their names, valid start and valid end dates, so we can incorporate them. While with HCPCS it’s relatively easy, NDC will require additional checks with the existing set of missing concepts. Sometimes we just see some random codes there like 9999999999
mappings are already on Athena,
except for
these two missed somehow, so we’ll add the mapping in the next run:
S0116 BEVACIZUMAB
J9020 Injection, asparaginase, not otherwise specified, 10,000 units
these can’t be mapped as they are very general
J3590 Unclassified biologics
J8499 Prescription drug, oral, non chemotherapeutic, nos
J8999 Prescription drug, oral, chemotherapeutic, nos
J9999 Not otherwise classified, antineoplastic drugs
S2107 Adoptive immunotherapy i.e. development of specific anti-tumor reactivity (e.g., tumor-infiltrating lymphocyte therapy) per course of treatment
S9338 Home infusion therapy, immunotherapy, administrative services, professional pharmacy services, care coordination, and all necessary supplies and equipment (drugs and nursing visits coded separately), per diem
