I have only one example. We make Dx claims conversion. Claims have services and each service (HCPCS / CPT4 / ICD9Proc / ICD10PCS) has a charge.
And only services with source code G8771 ‘Documentation of diagnosis of chronic kidney disease’ are mapped to Condition domain concept_id = 46271022 (SNOMED) ‘Chronic kidney disease’. So probably it is problem with mapping HCPCS to standard concept_id SNOMED
About cost_concept_id & cost_type_concept_id: probably this topic could help you: http://forums.ohdsi.org/t/cost-type-concept-id-for-patient-payment/4662
