athenahealth is different from most EHR platforms because it bundles billing services into the product itself. athenaOne combines an EHR, practice management, medical billing, and patient engagement into one system, with a network of more than 160,000 providers. Unlike platforms that sell software and leave billing to the practice, athenahealth’s model includes a rules engine, claim scrubbing, and revenue cycle services as part of the offering.

That model creates a specific question for independent practices: if athenahealth already handles billing, why would a practice need additional outside help?

The answer is that athenahealth handles a significant portion of the billing workflow, but it does not handle everything, and it does not replace the need for someone at the practice who understands what is happening with revenue. The platform is a strong billing infrastructure. Whether it provides enough billing control depends on the practice’s payer mix, denial patterns, volume, and how closely someone is watching the numbers.

How athenahealth’s billing model works

athenahealth uses a percentage-of-collections pricing model rather than a flat monthly fee or per-claim charge. The practice pays a percentage of what it collects, which means athenahealth’s revenue is tied to the practice’s revenue. That alignment is the core of the value proposition: athenahealth has a financial incentive to help the practice collect more.

athenahealth’s practice management page describes the platform as including medical billing software and services that work together. The billing rules engine contains tens of thousands of payer-specific rules that are continuously updated based on the collective claims experience of the provider network. athenahealth reports that its rules engine helps achieve a first-pass claim acceptance rate above 95 percent.

For an independent practice, this means the claim submission infrastructure is more sophisticated than what most practices could build in-house. The rules engine catches errors before claims go out. The clearinghouse is integrated. Eligibility checks, claim scrubbing, and auto-claim creation from clinical documentation are part of the workflow.

What athenahealth’s billing includes

With athenaOne, the practice gets:

  • Network-driven rules engine. Tens of thousands of payer-specific billing rules, updated continuously from the claims experience of the provider network. This is athenahealth’s primary differentiator.
  • Automated claim scrubbing. Claims are checked against the rules engine before submission, catching coding errors, missing fields, and payer-specific requirements.
  • Auto Claim Create. Claims can be generated automatically from clinical documentation, reducing charge-entry lag and manual data re-entry.
  • Real-time eligibility verification. Insurance status can be confirmed before the appointment, including AI-powered insurance card scanning that extracts and matches patient information.
  • ERA processing and payment posting. Electronic remittance advice is processed and payments are posted against claims.
  • Denial management services. athenahealth offers Enhanced Claim Resolution, where their billing team reworks certain denied claims to recover payments on the practice’s behalf.
  • Network benchmarking. The practice can compare its billing performance against athenahealth’s broader network, including first-pass acceptance rates, days in AR, and collection rates.
  • Reporting and analytics. RCM metrics, claim status tracking, and financial performance dashboards.

That is a more complete billing package than what most EHR platforms provide out of the box. For many independent practices, athenahealth’s billing services handle the bulk of the claim lifecycle.

What athenahealth does not automatically solve

Despite the breadth of athenahealth’s billing services, there are gaps that matter for independent practices.

Not all denials are worked

athenahealth’s denial management services do not cover every denied claim. Some claim types or denial categories may be referred back to the practice for resolution. If the practice does not have someone ready to handle those returned denials, the claims can go unworked and the revenue is lost.

This is especially relevant for practices with complex payer mixes, unusual service codes, or denial patterns that fall outside athenahealth’s standard denial workflows. The denials that come back to the practice are often the harder ones.

The practice still needs billing staff

athenahealth’s model assumes the practice has someone on staff who participates in the billing process. The platform handles much of the claim infrastructure, but charge entry, documentation quality, front-desk accuracy, patient eligibility issues, and certain denial follow-ups still require practice-side attention.

For a small independent practice where the office manager, front desk, or physician-owner is also the person responsible for billing, athenahealth’s services reduce the load but do not eliminate it. If nobody at the practice is watching the billing data, issues that athenahealth does not automatically resolve can accumulate.

Underpayment analysis is limited

athenahealth posts payments and provides reporting, but systematic underpayment analysis against contracted rates requires someone to compare what was paid against what was expected. If a payer is consistently paying less than the contracted amount, the underpayment may post without being flagged unless the practice or a billing partner is reviewing at that level.

Payer contract optimization

athenahealth can show the practice how it performs relative to the network. It does not negotiate payer contracts on the practice’s behalf or provide detailed contract-term analysis. For independent practices, understanding whether contracted rates are competitive and where renegotiation opportunities exist requires separate expertise.

Practice-specific workflow issues

athenahealth’s rules engine is built from network-wide data. It is excellent at catching common errors. It may not catch practice-specific patterns: a front-desk workflow that consistently creates eligibility problems, a documentation habit that leads to certain denials, or a scheduling pattern that affects charge capture. Those are operational issues that require someone who knows the individual practice, not just the network.

The percentage-of-collections model

athenahealth’s pricing model has implications that practices should understand.

The advantage is alignment: athenahealth earns more when the practice collects more, so there is a built-in incentive to improve collections. The practice does not pay for the platform when revenue is low.

The trade-off is cost at scale. As the practice grows and collects more, the dollar amount paid to athenahealth grows proportionally. A practice collecting significantly more revenue year over year is also paying significantly more for athenahealth’s services. At some point, the percentage fee may exceed what the practice would pay for a flat-rate billing service or a different pricing structure.

Practices should periodically calculate the actual dollar cost of athenahealth’s billing services relative to their collections and compare that against alternatives. The percentage model is not inherently better or worse than flat-rate or per-claim models. It depends on the practice’s volume, growth trajectory, and how much of the billing work athenahealth is actually performing versus what the practice is doing itself.

When additional outside help makes sense

Some practices on athenahealth find that the platform handles most of the billing workflow but leaves specific gaps that matter for their revenue.

Common signs that additional billing help is needed alongside athenahealth:

  • Denied claims are being returned to the practice and nobody is working them.
  • AR is aging in categories that athenahealth’s denial management does not cover.
  • The practice cannot explain why certain payers consistently underperform.
  • The billing person at the practice is stretched across too many roles to review athenahealth’s reports and act on them.
  • The owner sees athenahealth’s network benchmarks but does not know how to close the gap between the practice’s performance and the network average.
  • Patient-balance communication is inconsistent or creating friction.
  • The practice is growing and billing complexity is outpacing the current staff’s capacity.
  • The practice suspects underpayments but has no systematic process to identify them.

In those cases, the practice does not need to leave athenahealth. It may need a billing partner who can work alongside the platform: owning the denied claims athenahealth sends back, reviewing underpayments against contracts, providing practice-specific workflow analysis, and giving the owner a clearer monthly view of what is stuck.

When athenahealth’s billing is enough

Not every athenahealth practice needs additional help.

athenahealth’s billing may be sufficient if the practice has:

  • A clean first-pass acceptance rate and low denial volume.
  • Someone on staff who reviews athenahealth’s reports and follows up on returned denials.
  • AR that stays current without large aging balances.
  • Payer contracts that are recently reviewed and competitive.
  • Patient-balance policies that are clearly communicated.
  • Collections performance that matches or exceeds athenahealth’s network benchmarks.

If the practice is performing well on athenahealth’s own metrics and the owner has visibility into what is happening, the platform’s built-in services may be providing enough control.

What to check before deciding

Before deciding whether athenahealth’s billing is enough or whether additional help is needed, review:

  1. What percentage of denied claims does athenahealth work versus return to the practice?
  2. What happens to the claims athenahealth returns? Who works them, and how quickly?
  3. How does the practice’s first-pass rate, days in AR, and collection rate compare to athenahealth’s network benchmarks?
  4. Are payments being compared against contracted rates for each major payer?
  5. What is the actual dollar cost of athenahealth’s percentage fee, and how does it compare to alternatives?
  6. Does the owner have a monthly view of what revenue is stuck, which payers are creating rework, and what changed?
  7. Is the practice’s in-house billing capacity keeping up with volume growth?

If the answers are unclear, that is the signal. The practice may not need to leave athenahealth. It may need someone to work the gaps that the platform does not cover.

How Neobill can help

Neobill works with practices using athenahealth and other EHR and practice-management systems. For athenahealth practices, the free audit reviews claims, denials, AR, underpayments, payer performance, and the gap between athenahealth’s network benchmarks and the practice’s actual results. The goal is to identify whether the practice needs additional billing support around athenahealth or whether the platform’s built-in services are providing enough control.
