There's no such thing as 'pending' in this context.  The payer will either indicate "covered", "needs prior auth", "not covered", or one of the "unable to determine - need DTR" flavors.  We can't set any expectations about what percentage of orders will result in a determination without invocation of DTR because that's driven by the type of order, the type of information available in the order, and the type of information available elsewhere in the record and how computable it is.  It's also dependent on what the payer rules happen to be for a given payer's coverage.  It's in the payer's interest to maximize early determination because whatever can't be done in an automated fashion results in phone calls, human review and other factors that cost money.  It also provides a poorer patient experience. However, we will add the following language: "Where a payer responds with a "coverage information" code of 'clinical' or 'admin' and the payer supports DTR, they SHOULD support gathering the additional information via DTR.  This expectation is intended to change to SHALL in a future release."
