Network Adequacy Time and Distance: Why Routing Precision Matters

California regulators evaluate provider networks using detailed routing, tracing the roads a member would actually take to reach a provider. When a health plan's internal analysis uses a rougher method, its results and the regulators can disagree, and the plan usually learns that during review.

J2 now uses a GIS-based routing engine for time and distance measurement across the platform. It follows real road networks to calculate how long it takes members to get to care, so the drive times in your analysis reflect what members actually experience.

Why routing precision matters for network adequacy

Time and distance standards are the backbone of network adequacy, and they're only as reliable as the measurement behind them. Approximations can make a network look stronger on paper than it is in practice. That gap matters in a regulatory review, and it matters to a member trying to get to an appointment.

What changes in J2

Precise drive times are now built into J2's templates, alongside the relevant time and distance standards and your member data. Your team gets more accurate routing without building anything yourselves.

Where you'll see the biggest difference

Plans operating in states with detailed, state-specific requirements will feel this most. California is the clearest case, but any market where regulators look closely at drive time benefits from having your numbers line up with theirs before you submit.

What it means for your team

You get the measurement and the platform to act on it in one place: find gaps, test network changes, and prepare filings with confidence that your results reflect what members experience.
