H.Resources (Search Parameters - ExplanationOfBenefit Base Resource). I.HTML Page Names (https://www.hl7.org/fhir/explanationofbenefit.html). L.Sub-category (Enhancement). The current list of search parameters does not include a search parameter for insurer (Taylor, Pat:
Should the EOB profile only define PractionerRole instead of Organization?)

Existing Wording:

Does not currently exist

Proposed Wording:

Define a search parameter for the base EOB IG: name = insurer, type = reference, description = the party responsible for the claim, expression = ExplanationOfBenefit.insurer(Organization)
