SVC·01 · A/R and Denial Management

Denial management and A/R follow-up. Root cause first, then the work-down.

For the practice manager or CFO looking at aging A/R and a denial queue that keeps growing. Every denial is sorted by root cause, aged balances are worked biggest dollars first, appeals go out senior-reviewed, and the top causes are fixed upstream so the same denial stops coming back.

Six quick questions, about four minutes, no PHI required. Rather talk it through? Talk to a senior partner about denials.

How we work it
Root cause.
Then recovery.
Senior-reviewed appeals.
Nothing is written off without your sign-off. Every adjustment carries a reason code.
What this service covers

Two problems that feed each other. One team working both.

Unworked denials become aged A/R, and aged A/R hides the denials that caused it. We run denial management and A/R follow-up as one function: classify the denial, work the balance, appeal where the dollars justify it, and send the root cause back to the team that can stop it. You can bring us in for denials and A/R only, or as part of full revenue cycle management.

The A/R work-down

Five aging buckets. Five different moves.

A/R aging breaks your outstanding payer and patient balances down by days since service. Old A/R has a lower chance of collection, so each bucket gets its own action, and the oldest dollars get a senior decision instead of a default.

0-30 days
Wait

Claim is inside normal payer processing. Watch for rejections, do not chase.

31-60 days
Light touch

Claim status check by portal or call. Confirm it is on file and moving.

61-90 days
First call or appeal

Payer follow-up call. Denied lines move into the root-cause and appeal workflow.

91-120 days
Escalation

Escalated with the payer, with timely-filing limits tracked per payer.

Over 120 days
Senior partner review

Decision on each balance: keep pursuing, or a documented write-off recommendation for your sign-off.

Bar height shows touch intensity, not volumeAged from date of service

We age from date of service, not date of posting. Posting-date aging restarts the clock every time a claim is touched, which makes old A/R look younger than it is. More in our A/R aging glossary entry.

How the follow-up runs

Biggest dollars first. Every cycle.

A/R follow-up fails when it is worked by claim count. We work it by dollar value, on a cadence set per payer, with a written record of every touch.

01

Dollar-weighted prioritization

Work queues are ranked by balance size, account age and payment likelihood, so effort goes where it pays and not into accounts that will never collect.

  • Order of work: the biggest dollars get worked first, every cycle.
  • Visibility: dollars resolved shown in the monthly scorecard, not just calls made.

Payer follow-up and claim status

Follow-up is scripted by line of business and run on payer-specific call and portal rhythms, not a generic 30/60/90 schedule, and tracked to a written cadence.

Self-pay balances and insurance discovery

Some accounts marked self-pay have coverage the front desk never captured. Self-pay accounts under 365 days from service run through a monthly discovery sweep, every hit is confirmed with a 270/271 eligibility check, and confirmed coverage moves back into billable A/R.

Payer A/R and patient A/R, kept separate

Payer A/R needs appeals, status calls and contract enforcement. Patient A/R needs statement cadence and payment plan offers. Different workflows, so they are run and reported separately.

Denial root-cause taxonomy

Every denial gets a root cause, not just a status.

The reason code tells you what the payer did. It is the first sentence of the story, not the last. Before anything is appealed, each denial is classified into one of five lanes, because each lane is fixed by a different team.

LANE 01
Clinical

Medical necessity and documentation. The service was billed, but the chart or the payer policy did not support it.

Fixed by: LCD and NCD policy checks before submission, and documentation feedback to the provider.
LANE 02
Eligibility

Coverage terminated, the wrong payer billed, or another payer primary under coordination of benefits.

Fixed by: real-time eligibility at every visit and a COB check at intake.
LANE 03
Authorization

Precertification absent, expired, or not matching the units, dates or codes billed.

Fixed by: an auth tracker that ties auth number, units, date span and service codes to the claim.
LANE 04
Coding

Diagnosis inconsistent with the procedure, bundled services, or modifier problems.

Fixed by: DX-to-CPT checks and NCCI edits at coding. See our medical coding services.
LANE 05
Registration

Missing or invalid claim information, demographic errors and duplicate submissions.

Fixed by: a pre-submission validator on modifiers, units, place of service and referring provider.
WHY CLASSIFY FIRST
Fewer denials, not faster appeals.

The top five root causes each month feed upstream fixes at the front desk, in coding and in authorization. That is how the denial queue gets shorter instead of just getting worked faster.

Reason codes we see every week

Common CARCs, the lane that owns them, and the fix.

Claim Adjustment Reason Codes are the X12 standard codes payers attach to claim lines in the 835 remittance. Each one maps to a lane, and each lane has a prevention move. The full list is in our CARC code reference.

How an appeal is built

Read the chart before writing the appeal.

The move after a denial is to read the chart and the authorization, not to file the appeal. Some denials are corrected and resubmitted. Some are appealed. A few are not worth pursuing, and that decision is written down.

STEP 01
Read the remit

CARC and RARC from the 835 identify what the payer did and on which line.

STEP 02
Read the chart and auth

Documentation, authorization and eligibility are checked against the denial before anything is written.

STEP 03
Decide the path

Correct and resubmit, appeal, or recommend write-off. The decision carries a reason code.

STEP 04
Written appeal pack

High-dollar lanes get a written appeal pack. Every appeal is senior-reviewed before it goes out.

STEP 05
Close the loop

Outcome tracked, and the root cause routed back to coding, eligibility or the front desk.

Medicare fee-for-service appeals follow the CMS appeals process, which starts with a redetermination by the Medicare Administrative Contractor. Other payers set their own appeal requirements, so each pack is built to the payer, not to a template.

Prevention

Catch the denial before the claim leaves.

Recovery work pays for itself only once. Prevention keeps paying. The same root-cause data that drives appeals also drives a check at the submit gate.

PRE-SUBMIT SCORING

Every claim line scored. Before submission.

Our denial prediction engine scores each claim line for denial risk, the most likely CARC and the recommended action, against more than 80 tracked CARC patterns. See the denial prediction engine.

WHAT HAPPENS TO A FLAGGED LINE

Fix it, route it, or log it.

  • Auto-correct, only on deterministic patterns where the fix is unambiguous, such as a missing referring NPI. Every correction leaves an audit-trail entry.
  • Specialist route for judgment calls like medical necessity or documentation gaps. These never auto-correct.
  • Root-cause loop: when a denial posts, the cause feeds back to coding, eligibility or credentialing.

Questions buyers ask

Denials and A/R, answered plainly.

Can you work A/R that is already over 90 or 120 days old?

Yes. Aged A/R is worked by dollar value, biggest balances first. Claims in the 91-120 day bucket are escalated with the payer. Anything over 120 days gets a senior partner review that decides, claim by claim, whether to keep pursuing it or recommend a write-off. Timely filing limits are tracked per payer, with claim-aging alerts well ahead of each window. We do not promise a recovery figure before we have read your aging report.

How do your appeals work?

Root cause first. We read the CARC and RARC on the remittance, then the chart and the authorization, before anything is written. If the claim can be corrected and resubmitted, it is. If it needs an appeal, the high-dollar lanes get a written appeal pack, and every appeal is senior-reviewed before submission. Medicare appeals follow the CMS appeals process, which starts with a redetermination by the Medicare Administrative Contractor.

Which denials do you work?

All of them, sorted into five root-cause lanes: clinical (medical necessity and documentation), eligibility (terminated coverage, wrong payer, coordination of benefits), authorization (precertification absent or mismatched), coding (diagnosis and procedure conflicts, bundling) and registration (missing or invalid claim information, duplicates). Each lane is fixed by a different team, so the lane decides who gets the feedback.

Do we need to change our EHR or practice management system?

No. We work inside your existing EHR and PM system and do not require a system change to engage. Access is provisioned during onboarding, and we sign a BAA at the start of the engagement.

Will you write off our old balances?

Only with your sign-off. Nothing is auto-written off. Every adjustment carries a reason code, and balances over 120 days get a senior partner review for write-off versus continued pursuit. When a write-off is recommended, you see the dollar value and the reason before it is posted.

How do we get started?

Run the free denial audit: six quick questions, about four minutes, no PHI required, and a 2-page PDF report. If you would rather start smaller than full RCM, we take on focused engagements such as denial management only or A/R cleanup only.

How is pricing quoted?

In writing, by a senior partner. Tell us your specialty, monthly claim volume, EHR or PM system and payer mix, and mention aging A/R or rising denials in the message box. You get a written quote within one business day, locked for the contract term. We do not publish a rate, because a fair price depends on your book.
