Which statement best describes network adequacy metrics?

• A. Geographic distribution is not relevant to network adequacy.
• B. Wait times for appointments are not a typical metric.
• C. Provider-to-member ratios alone determine adequacy.
• D. Appointment availability, geographic distribution, provider-to-member ratios, and wait times are all typical metrics used to assess network adequacy.

Answer: (D)

Network adequacy is about ensuring members have timely, convenient access to in-network care. To evaluate adequacy, you look at multiple metrics that capture different access dimensions: appointment availability shows whether you can get an appointment within a reasonable timeframe; geographic distribution assesses whether providers are located where members live or work; provider-to-member ratios indicate whether there are enough providers relative to the covered population; wait times reflect the actual time patients spend waiting to receive care after seeking it. Taken together, these metrics provide a complete picture of access. Therefore, the statement that lists appointment availability, geographic distribution, provider-to-member ratios, and wait times as typical metrics is the best description. Focusing on just one aspect, like counts of providers alone or geographic spread alone, would miss other barriers to access such as long wait times or insufficient provider availability in certain areas.
