Definition and scope
What accounts receivable means in medical billing
Accounts receivable, or A/R, is the open balance recorded after a healthcare service has been billed but has not been fully paid, adjusted or otherwise resolved. The balance may involve an insurer, a patient or another responsible party. The record needs more than an age and amount: it also needs a verified status, reason, owner, last action, next action and applicable deadline.
A/R management is not a promise to collect every balance. Coverage, contract terms, documentation, payer rules, prior submissions and filing limits can make some balances nonrecoverable. The first control is validating the inventory before projecting any outcome.
What a scoped A/R engagement can include
Claim-status follow-up
Use the available clearinghouse, payer portal, electronic status response or documented contact channel to establish the current claim position.
Exception resolution
Route rejections, denials, documentation requests, posting differences and enrollment or authorization issues to the responsible workflow.
Corrected claims and appeals
Follow the applicable payer, product and date-specific instructions only when the record supports the chosen correction, reconsideration or appeal path.
Action tracking
Record evidence, contact reference, action date, owner, next step and follow-up date so the same claim is not repeatedly researched without progress.
Management reporting
Separate inventory movement from cash posting and contractual adjustments, with metric definitions, dates, exclusions and unresolved blockers.
The final scope should state which payer and patient balances are included, who approves write-offs or appeals, which systems are authoritative, and what information the practice must provide. Patient statements or collection activity should follow the practice's approved financial policy and applicable requirements.
Controlled workflow
How medical billing A/R follow-up should work
One claim may pass through several systems. The work queue should preserve evidence and ownership at every handoff.
- Validate the balance
Confirm the charge, payment, adjustment and responsible party before follow-up.
- Establish status
Review clearinghouse acceptance, payer adjudication, remittance and portal or transaction responses.
- Identify the barrier
Classify the issue without assuming that every open balance is a denial.
- Choose the next action
Correct, submit information, post an adjustment, appeal, escalate or hold with a documented reason.
- Set ownership and timing
Assign the action, record the payer-specific deadline and schedule the next review.
- Reconcile the outcome
Match remittance, payment and adjustment records before closing the item.
- Feed back the cause
Route recurring issues to eligibility, authorization, coding, enrollment, submission or posting.
- Report with definitions
Keep opening inventory, additions, resolved items, exclusions and ending inventory traceable.
Aging and priority
Use age bands to organize work, not to predict recovery
| Age band | Questions to verify | Control |
|---|---|---|
| 0–30 days | Was the claim accepted, and is it still within the payer's normal processing window? | Avoid unnecessary duplicate submissions. |
| 31–60 days | Is status available through the payer, portal, clearinghouse or 276/277 workflow? | Document the status source and next review date. |
| 61–90 days | Is an information request, rejection, denial, posting issue or enrollment problem blocking resolution? | Route to the correct owner before a deadline is at risk. |
| 91–120 days | Have filing, correction, reconsideration and appeal rules been checked for the exact payer and product? | Escalate deadline risk with supporting evidence. |
| 121+ days | Is the balance accurate and actionable, and does the record support any remaining administrative path? | Separate viable work from contractual, duplicate, invalid or unsupported balances. |
These bands are operational categories, not payer deadlines or collection benchmarks. For Medicare fee-for-service claims, CMS states that the general timely-filing period is one calendar year from the date of service, subject to specific rules and exceptions. Commercial and Medicaid requirements vary by payer, product, contract, state and action type.
Systems and evidence
Use the right source for each A/R question
Practice-management or EHR billing record
Charge, claim, responsible party, work notes, attachments and account-level history. Access should follow approved roles and the minimum information needed.
Clearinghouse
Submission, acceptance and rejection evidence. Acceptance by a clearinghouse does not by itself establish payer adjudication or timely filing.
Payer or MAC
Claim status, remittance, requests for information, reconsideration or appeal channel, and current product-specific instructions.
Bank and posting reconciliation
Payment receipt, electronic funds transfer trace, 835 remittance and posting exceptions. A posted amount should not be treated as a bank deposit without reconciliation.
CMS identifies MAC portals, interactive voice response and the standard 276/277 claim-status transaction as Medicare status channels. CMS also explains that the 835 remittance can support automated posting but includes claim-level and provider-level adjustments that still need reconciliation.
Automation or AI can prioritize queues, apply approved routing rules and surface missing fields. It should not independently decide coverage, create documentation, choose an appeal path or close a balance without human verification. Before relying on any EHR, clearinghouse or billing-software function, confirm the practice's actual configuration, access, audit history and vendor documentation. ERG does not claim certification or partnership with a software vendor on this page.

Deadlines and payer instructions
Timely filing, corrections and appeals are not interchangeable
A claim-status result should lead to the correct action, not an automatic appeal. A clearinghouse rejection may require correction before payer adjudication. A denied claim may require a corrected claim, reopening, reconsideration or appeal depending on the payer's rules and the record. Every action should be tied to the current payer instructions and a saved source date.
- Medicare fee-for-service example: CMS's current Chapter 1 generally uses one calendar year from the date of service for claim filing. CMS separately states that a redetermination request is generally due within 120 days from receipt of the initial determination.
- Current CMS change: CMS issued Transmittal R13992CP on October 8, 2026, revising Chapter 29 appeals guidance for implementation December 11, 2026. Teams should use the instructions in effect on the date they act and check their MAC's current submission channel.
- Named payer example: UnitedHealthcare requires electronic post-service appeal submission beginning February 1, 2026 for most network commercial and Medicare Advantage professionals and facilities. This example does not establish a universal payer rule.
Deadline control: store the payer, product, jurisdiction, source URL, source date, action type and deadline together. A generic deadline field without that context is unsafe.
Reporting and governance
What an A/R report should let a practice verify
Inventory
Opening and ending balances by age, payer, provider, location or other agreed dimension, using one documented aging basis.
Work status
Last action, next action, owner, follow-up date, deadline risk, missing evidence and items blocked by practice or payer input.
Resolution
Paid, adjusted, transferred, corrected, appealed, closed or otherwise resolved items, with definitions that prevent double counting.
Measure days in A/R with a stated formula and denominator. Define whether charges are gross or adjusted, which dates determine the period and how credits or old balances are treated. Do not compare rates until the numerator, denominator, cohort and exclusions match.

Privacy and accountability
Protect PHI while keeping the work auditable
HHS identifies claims processing, billing and practice management as activities that can make a vendor a business associate when the work involves protected health information. The permitted work, safeguards, subcontractor responsibilities and incident duties should be addressed in the applicable agreements. Access should be limited to the roles and information needed for the approved task.
OIG's General Compliance Program Guidance, released November 6, 2023, is voluntary guidance that describes compliance risks and program infrastructure. For A/R work, practical controls include written responsibilities, training, monitoring, documented escalation and correction of recurring causes. The public ERG contact form should contain operational context only—never patient names, account numbers, claim files or other PHI.

Medical A/R management FAQs
Questions about this service
What does A/R mean in medical billing?
A/R means accounts receivable: balances recorded for services that have been billed but remain unpaid or unresolved. A useful A/R record includes the payer or responsible party, age, current status, last action, next action and deadline.
Is medical billing the same as A/R follow-up?
No. Medical billing covers the broader claim workflow. A/R follow-up begins after a balance is created and focuses on identifying why it remains open, completing the correct next action and documenting the result.
Can every old medical claim be recovered?
No. Recoverability depends on the payer and product, filing and appeal rules, coverage, documentation, prior actions, contractual adjustments and whether the balance is accurate. Age alone does not establish recoverability.
How should aged A/R be prioritized?
Prioritization should consider deadline risk, balance validation, payer status, documentation readiness, next-action clarity and whether the issue affects other claims. Age bands help organize work but should not be the only rule.
What systems support medical A/R follow-up?
The practice-management or EHR billing record, clearinghouse reports, remittance data, payer portals and documented calls may all provide evidence. The authoritative source depends on the question, and access should follow the practice's approved roles and safeguards.
Can automation or AI replace A/R review?
Automation can organize queues, apply approved routing rules and surface exceptions, but payer instructions, documentation, coverage and appeal choices still require human verification. No automated status should be treated as a payment guarantee.
How does ERG price A/R management?
ERG does not publish pricing publicly. Pricing is customized to the practice's services and needs after the inventory, systems, responsibilities and reporting scope are reviewed. Request Pricing.
What should an A/R report show?
A useful report can show balances by age, payer, provider or location; unresolved status and reason; last and next action; deadline risk; ownership; and separately defined resolution outcomes. The report should preserve the denominator, date and exclusions for every rate.
