From @galozins : "we have noticed multiple groups of records in PCORNET_PROC ontology with the same concept_path and c_basecode, and "no qualifier" values in the c_name column. These records seem to be synonyms to valid c_name values.
Here is an example:
C_NAME C_BASECODE C_SYNONYM_CD
Occlusion of left external iliac vein, percutaneous endoscopic approach ICD10-PCS:06LG4ZZ N
no qualifier ICD10-PCS:06LG4ZZ Y
no qualifier ICD10-PCS:06LG4ZZ Y"
@lcphillips2 has confirmed these have no utility and should be deleted
