The basics

What is denial management in healthcare?

Denial management is the work of recovering payment on claims a payer has refused, and preventing the same refusals in the future. It covers four jobs: sorting denials by reason code and payer, correcting and resubmitting or appealing each claim before its deadline, following up until the payer pays, and fixing the upstream step, such as registration, authorization or coding, that caused the denial.

Denial management

Claims the payer said no to

Work starts from the claim adjustment reason code (CARC) and remark code (RARC) on the remittance. Each code points to a different fix.

AR recovery

Claims nobody has paid yet

Work starts from the aging report: every open balance by payer and age. It catches claims the payer never processed, underpaid or quietly lost.

Why both

One feeds the other

A denial nobody works becomes aged AR, and aged AR hides denials nobody has seen. We run them as one workflow with one owner per claim.

Industry data

More than half of private-payer denials are paid on appeal

Denied does not mean lost. The cost is the work of appealing, so the goal is to appeal efficiently and stop repeat denials at the source.

Denial codes

The denial codes we see most, and how we fix each one

Every remittance carries a claim adjustment reason code. The group prefix tells you who owes: CO is the provider's contractual obligation, PR is patient responsibility. Pick a code.

CO-16Correct and resubmit

The claim lacks information or has a submission or billing error.

Common cause

A missing or invalid field: rendering or referring provider NPI, a modifier, a date span. The remark code (for example N290 or MA130) names the field.

How we fix it

Read the remark code, correct that field and send a corrected claim. CO-16 is fixed with a resubmission, not an appeal.

How we prevent it

Add a claim scrubber edit for that payer and field so the error is caught before the next claim goes out.

Code descriptions paraphrased from the X12 claim adjustment reason code list.

Our process

How we work a denial, from remittance to root cause

Every denial gets an owner, a deadline and a reason. Nothing sits in a queue without a name on it.

  1. Capture

    Every electronic remittance (835) and payer letter is read the day it arrives. Denials are tagged by reason code, payer, provider and dollar value.

  2. Prioritize

    The queue is worked by deadline and dollars: claims closest to an appeal or filing limit first, then the largest balances.

  3. Resolve

    Corrected claim, reopening or appeal, with the records, policy citation and letter each payer expects. Coders take coding denials; AR specialists take payer issues.

  4. Follow up

    Our AR voice agent calls payers for claim status on a schedule and logs every answer on the claim. People take the calls that need judgment.

  5. Prevent

    Denial analysis groups denials by root cause. We fix the step that caused them: a registration field, an authorization rule, a scrubber edit or a documentation template.

AR recovery

AR recovery services, worked by age bucket

Receivables get harder to collect the older they get. We split your aging report into buckets and work each one differently, oldest money with a deadline first.

Denial management and AR recovery questions

What do denial management services include?

Reading every remittance for denials, sorting them by reason code and payer, correcting and resubmitting or appealing each claim before its deadline, following up with the payer until it pays, and fixing the upstream cause, such as a registration field, an authorization rule or a coding pattern, so the denial does not repeat.

What is the difference between denial management and AR recovery?

Denial management works claims the payer has refused, starting from the denial code. AR recovery works every unpaid balance on the aging report, including claims the payer never processed or underpaid. A denial that is not worked becomes aged AR, so we run both as one workflow.

What is a good claim denial rate?

There is no single official benchmark. In Experian Health's 2025 State of Claims survey, 41% of providers reported denial rates of 10% or higher, so a rate in the single digits puts a practice ahead of many peers. We report your rate by payer and by root cause, which shows what to fix.

Can AR older than 120 days still be collected?

Often, yes. If the claim was filed on time and you can prove it, it can usually still be appealed or reprocessed. For Medicare, a redetermination must be requested within 120 days of receiving the initial determination; commercial appeal deadlines are set by each contract. Claims past every deadline are written off with a documented reason so your AR is accurate.

What does denial code CO-197 mean?

CO-197 means the payer found no precertification, notification or authorization for the service. It is fixed by matching an existing authorization to the claim, requesting a retro-authorization where the payer allows it, or appealing with the clinical record, and prevented by checking authorization at scheduling.

What does denial code CO-16 mean?

CO-16 means the claim lacks information or has a billing error. The remark code on the remittance names the missing or invalid field. It is fixed by correcting that field and sending a corrected claim, not by an appeal.

How do you start?

With a review of your aging report and your last 90 days of remittance data. It shows where the money is and which denials repeat. Work starts once system access and a business associate agreement are in place.

Can you work our denials if we keep billing in-house?

Yes. We can take denials and aged AR as a standalone service while your team keeps charge entry and the front desk. You can also license our denial analysis and AR voice agent for your own staff.
