We will define an extensible binding that includes the following concepts: coverage - is the therapy covered or not or are there limitations prior-auth - is prior authorization required or not (and possibly provision of unsolicited prior authorizations) dtr-clin - indication that DTR is relevant for prior authorization, claim or other documentation requirements and that at least some clinical information needs to be captured dtr-admin - indication that DTR is relevant for prior authorization, claim or other documentation requirements and that all information to be captured is strictly administrative (and thus it is not necessary that the app be launched by the ordering clinician) claim - information about what steps need to be taken to submit a claim for the service insurance - allows a provider to update the patient's coverage information with additional details from the payer (e.g. expiry date, coverage extensions) limits - messages warning about the patient approaching or exceeding their limits for a particular type of coverage or expiry date for coverage in general network - providing information about in-network providers that could deliver the order (or in-network alternatives for an order directed out-of-network) appropriate-use - guidance on whether appropriate-use documentation is needed cost - what is the anticipated cost to the patient based on their coverage therapy-alternatives-opt - are there alternative therapies that have better coverage and/or are lower-cost for the patient therapy-alternatives-req - are there alternative therapies that must be tried first prior to coverage being available for the proposed therapy clinical-reminder - reminders that a patient is due for certain screening or other therapy (based on payer recorded date of last intervention) duplicate-therapy - notice that the proposed intervention has already recently occurred with a different provider when that information isn't already available in the provider system contraindication  - notice that the proposed intervention may be contraindicated based on information the payer has in their record that the provider doesn't have in theirs guideline - indication that there is a guideline available for the proposed therapy (with an option to view) off-guideline  - notice that the proposed therapy may be contrary to best-practice guidelines, typically with an option to view the relevant guideline
