What Is Patient Access? Functions, Metrics and How Health Systems Improve It

What You Need to Know

• Patient access is how easily patients can reach your organization and get timely care from the right provider¹. It covers the front-end work from first contact through payment at the visit.
• In a 2024 Patient Access Collaborative benchmark report, US patients waited a median 26 calendar days for a new patient appointment¹.
• To improve it, put one leader over the whole front end and measure each function before you change anything.

What is patient access in healthcare?

Patient access is how easily patients can reach your organization and get timely care from the right provider¹. Day to day, it's the front-end work from first contact through payment at the visit.

Access to care is what patients get, and patient access is the work behind it. The Agency for Healthcare Research and Quality (AHRQ) defines access to care as "the timely use of personal health services" to reach the best outcomes². Wait times are one way to see that work. In a 2024 Patient Access Collaborative benchmark report, US patients waited a median 26 calendar days for a new patient appointment¹.

In one study of 89 Veterans Affairs (VA) medical centers, veterans seen in geriatric clinics had higher odds of death where waits ran 31 days or more³. Their odds of dying within six months were 1.21 times those at centers with shorter waits³. The study used 2001 data and doesn't establish cause³.

What is patient access responsible for, function by function?

Patient access covers seven front-end functions, from booking and registration to the phone line. The Healthcare Financial Management Association (HFMA) publishes formulas, called MAP Keys, for five of them⁴. HFMA has no key for the other two, referral management and the contact center⁴.

For scheduling, the guide to types of appointment scheduling compares how each model fills open slots.

For financial clearance, the No Surprises Act requires providers to give uninsured and self-pay patients a good faith estimate when they ask for one⁵. Providers must also give one for any service booked three or more business days ahead⁵.

Any discussion of potential costs with an uninsured or self-pay patient counts as a request for an estimate⁵. When these patients schedule or ask about cost, providers must tell them orally that an estimate is available⁵. They must also post the notice in writing on their websites, in their offices and wherever scheduling or cost questions happen⁵.

Under 45 CFR 149.610, self-pay patients are those with an employer, individual or federal employee health plan who don't plan to have a claim submitted for the service⁶. Patients with Medicare, Medicaid or other federal health care program benefits for the service aren't self-pay under the rule⁶. Before you build the workflow, check the rule's delivery deadlines and other steps.

Which patient access metrics should you track?

Patient access metrics work at two levels: whether each function ran on time and correctly, and whether patients got care when needed².

For the first level, 7 of HFMA's 29 MAP Keys measure patient access, each with a set, objective formula⁴. The MAP Keys page lists no benchmark values, and HFMA offers benchmarking to subscribers of its MAP App⁴. Without the app, set targets from your own baseline.

For the second level, AHRQ tracks whether adults who needed care right away got it as soon as needed². The share who sometimes or never did fell from about 15% in 2002 to 13% in 2017².

Inside a practice, third next available appointment can stand in for that outcome. It counts the days from a patient's request to the provider's third open slot. The guide to third next available appointment shows how to measure it.

Phone access sits between the two levels. Veterans at the slowest-answering quarter of 285 VA primary care sites were less likely to say they got urgent care as soon as needed⁷. Their odds were 0.85 times those of veterans at the fastest quarter⁷.

The study covered only veterans, and abandonment rates in it showed no clear link to any outcome measured⁷. The guide to healthcare call center metrics defines speed of answer and abandonment. The guide to healthcare call center best practices covers how to set answer-speed targets.

What makes patient access hard to run well?

Three things make patient access hard: phone time on eligibility and prior authorization⁸, payer control over part of the approval clock⁹ and split priorities among leaders¹⁰.

In a March 2026 Medical Group Management Association (MGMA) poll, 45% of practice leaders said eligibility and prior authorization take the most phone time⁸. Scheduling came second at 31%⁸. An AI vendor sponsored the poll⁸.

A Centers for Medicare & Medicaid Services (CMS) rule in force since 2026 limits how long some payers can take on prior authorization⁹. Medicare Advantage, Medicaid and Children's Health Insurance Program (CHIP) payers must decide urgent requests within 72 hours and standard ones within seven calendar days⁹. These deadlines cover items and services other than drugs⁹.

In limited cases, Medicare Advantage and Medicaid managed care plans can extend the standard deadline by up to 14 calendar days¹¹,¹². A patient asking for more time is one of those cases¹¹,¹². Other allowed reasons differ by program, so check each extension notice against the rule. The deadlines bind payers, but your access team still prepares, submits and tracks each prior authorization request.

Practice leaders also split on where to focus¹⁰. In a December 2025 MGMA poll, 27% named no-shows their top access focus for 2026¹⁰. Online scheduling followed at 24%, phone access at 22% and wait times at 21%¹⁰.

What does improving patient access take?

Improving patient access takes work on structure, process and outcomes, according to a framework from a 2025 study of US health system leaders¹.

• Structure covers executive support, dedicated access leadership and access as a strategic priority.
• Process covers data collection and analysis, contact center management, capacity management, appointment availability and accuracy, and measurable goals.
• Outcomes cover a simpler system for patients, timely offering of care and patient-clinician connection.

The study's panel included only leaders from academic health systems and children's hospitals, and no patients¹. Its authors note the findings may not carry over to smaller or non-academic hospitals and health systems¹.

Growing demand is a separate job, covered in the guide on how to increase patient volume.

Centralized scheduling teams

A centralized scheduling team books for several clinics from one queue, using the same booking rules. That puts two of the panel's process factors, capacity management and appointment accuracy, in one team's hands¹. The guide to centralized scheduling covers how to roll one out.

Patient self-scheduling

Self-scheduling lets patients book routine visits online, outside phone hours. Set online booking to use your phone team's templates and open slots, so both channels fill one schedule. Check its visit-type rules before launch. The digital front door guide covers how online scheduling fits with other patient engagement channels.

AI agents on the phone line

AI agents answer inbound calls, handle requests such as booking, rescheduling and routine questions, and send other calls to staff. The guide on how AI agents expand call center capacity covers the category.

In an August 2025 MGMA poll, 71% of practice leaders reported some use of AI in patient visits¹³. Among them, 39% said it had reduced staff workload, 44% said it hadn't and 17% weren't sure¹³.

Where should a patient access leader start?

Start by putting one leader in charge of the whole front end. Then measure where each function stands before you change anything, using HFMA's formulas for the five functions that have them⁴.

Write each metric's definition, exclusions and data source next to its number. That way the baseline holds up when staff change. Each quarter, report one of the panel's outcomes, such as timely offering of care, to senior leadership.

Your baseline gives three inputs for the Access Center Recoverable Revenue Calculator: monthly call volume, missed call rate and schedule utilization. It also asks for annual patient billings and the shares of calls for scheduling and for new patient intake.

Its estimate of recoverable revenue is rough, and your open slots cap it, so a fully booked schedule returns zero.

Map where patients drop out between referral, call and booked visit, and rank the fixes by what they're worth. The guide to patient leakage covers how to measure referrals that never become visits. The guide to patient lifetime value shows how to estimate a retained patient's worth over time.

Which patient access calls can Commure AI Call Center Agents handle?

Commure AI Call Center Agents cover the phone side of three patient access functions: the contact center, scheduling and registration. They answer at any hour in English or Spanish, route callers, and book and move appointments. They also enter registration and insurance details in the electronic health record (EHR). Anything outside the rules you set goes to your staff.

Agent bookings still count as scheduling under the No Surprises Act⁵. So the good faith estimate rules covered under financial clearance apply to these callers⁵. During scoping, decide how they hear the notice and how your team learns of their bookings in time.

Your team keeps eligibility checks, prior authorization, estimates and payment collection. Commure RCM, Commure's revenue cycle management (RCM) product, automates steps in eligibility and prior authorization, and Commure Orchestrator handles referral management. To see how your calls split across these functions, ask for a complimentary call center health analysis.
