Define the population and standard
Record the covered population, geography, provider type, service line, travel threshold, availability assumptions, and applicable regulatory context.
Resolve provider locations carefully
Distinguish practice location, billing location, facility affiliation, and service availability. An address match alone does not prove access.
Model availability and capacity
A nearby provider may not be available to the population or have sufficient capacity. Keep these inputs separate from distance.
Test alternatives
Compare the current network with candidate additions or removals while preserving the same standards and assumptions.
Document uncertainty
Identify missing participation, availability, capacity, and specialty evidence rather than silently treating it as adequate.
