AR Audit and Recovery Insights

Prepared for a behavioral health and SUD network in Virginia · Multi-facility · Trailing 30 days

Sample · synthetic data

Source: Claim.MD ERA + AR aging exports

Engagement: rapid 3-day AR audit

This is a representative sample, not a real engagement. All names, payer behaviors, claim counts, and dollar amounts are synthetic but built to be internally consistent and recognizable to RCM, finance, and compliance professionals. A real engagement carries your data, your payers, and your service lines, with first findings delivered in under three days after receipt of core data.

Executive snapshot

A behavioral health network with four facilities and roughly 1,000 claims per month. Window: trailing 30 days. Numbers tie line-for-line to the ERA totals in the synthetic Payments / Adjustments dataset.

Biggest single leak

Credentialing and enrollment denials · $144,138/month

CO-B7 ($125,520) means the rendering provider was not certified or enrolled with the payer for that service on that date. CO-256 ($18,618) is the contract-level twin. When a provider or location isn't active with a payer, every claim they send denies until the gap is closed. At this volume, the clinical work is being done; the dollars are being lost upstream.

The rule behind each denial, and exactly what we do

For your billing team: the specific failure, the regulation or coding rule it violates, and the pre-submission control that prevents it.

Credentialing / enrollment

CO-B7 · CO-256

$144,138/mo
The problem

Claims billed under a rendering provider or location not yet active with that payer for the date of service. When clinician enrollment lags their start date, every claim in the gap denies.

The rule

Medicaid provider screening and enrollment under 42 CFR Part 455, Subpart E, and managed-care plan enrollment under 42 CFR 438.602(b). Payers do not pay for services dated before the credentialing effective date with that plan; each Cardinal Care MCO holds its own effective date.

What Adentris does

Maintains a live provider-payer enrollment matrix (NPI × plan × effective date × service). Before a claim is built it checks rendering provider status with the destination payer for the DOS. If not active, holds the claim and routes to enrollment instead of letting it deny. Where retro-enrollment is allowed, flags the recoverable window.

Authorization / precert

CO-197 · CO-39 · CO-198

$81,524/mo
The problem

Auth-required services billed with no auth on file (CO-197), units exceeding what was authorized (CO-198), or denial at the time auth was requested (CO-39). In BH/SUD this hits residential, PHP and IOP hardest.

The rule

Each payer's prior-authorization policy; for SUD levels of care these track the ASAM Criteria for medical necessity, and Virginia Medicaid ARTS requires service authorization for higher levels of care. Note: crisis intervention (H2011) is commonly auth-exempt, so "no auth" denials on H2011 are often incorrect and appealable.

What Adentris does

Flags every line that needs auth for that payer and level of care, checks valid auth (units and date span) is on file, and opens an auth task if not. For wrongly-denied auth-exempt services (the H2011 pattern at Aetna and Sentara) it assembles the appeal with the policy citation.

Duplicate submissions

OA-18 · CO-18 · PI-B13

$47,144/mo
The problem

The same service was submitted twice and the payer denied the duplicate. The original usually already paid, so this isn't lost revenue, it's wasted rework and added A/R days from resubmitting instead of checking status.

The rule

Payer duplicate-claim logic and NCCI duplicate / frequency edits. A service already adjudicated denies as a duplicate (CO-18 / OA-18) or as previously paid (B13).

What Adentris does

Before sending, checks claim history for matching prior submission (member, DOS, code, units, provider) and its status. If an original is pending or paid, suppresses the duplicate and surfaces the real action: check status, post payment, or appeal the original.

Coding

CO-4 · CO-189 · CO-151 · CO-97

$12,531/mo
The problem

Required modifier missing or inconsistent (CO-4); unlisted code billed where specific one exists (CO-189); units / frequency unsupported (CO-151); line bundled into another service (CO-97).

The rule

CPT / HCPCS modifier rules and the CMS National Correct Coding Initiative: Procedure-to-Procedure (PTP) edits for bundling (CO-97) and Medically Unlikely Edits (MUEs) for units (CO-151); payer policy requiring specific HCPCS over unlisted code (CO-189).

What Adentris does

Runs the coded claim through modifier appropriateness, MUE unit limits, NCCI PTP bundling and unlisted-to-specific mapping before submission. For United's H0046 "unlisted" (CO-189) maps to the accepted code; where a PTP edit applies, checks the modifier is clinically justified before adding one.

Documentation quality findings

From a sample of 84 charts associated with denied claims. Patterns visible at this sample size are very likely systemic.

Missing or weak medical necessity language

14 of 84 charts

Notes describe service delivery without explicitly establishing why the level of care was medically necessary. Disproportionately concentrated in PHP and IOP level transitions.

Affects · CO-197, CO-251 denials

Level-of-care defensibility gaps

11 of 84 charts

ASAM dimensional findings not consistently tied to recommended level. Concurrent review records support level of care but the original admission note often does not.

Affects · auth and recoupment risk

Late or missing clinician signatures

8 of 84 charts

Signatures attached more than 72 hours after service or missing on group counseling notes. Creates evidentiary problems on appeal.

Affects · audit defensibility

Treatment plan and billed service mismatch

6 of 84 charts

Billed services not represented in the active treatment plan, or treatment plan not updated to reflect current level of care.

Affects · CO-226 denials, payer audits

Concurrent review evidence gaps

3 of 84 charts

Continued-stay reviews missing or not aligned to the payer's expected cadence. Higher exposure on residential stays beyond 14 days.

Affects · concurrent review denials

Discharge summary completeness

5 of 84 charts

Missing or partial discharge summaries on closed episodes. Limits ability to defend the full episode and slows next-level handoffs.

Affects · payer post-pay reviews

Compliance and audit risk register

Payer audit signals, SIU exposure, documentation defensibility issues, and recordkeeping gaps that require leadership attention.

High
Sentara records requests on 18 BH residential stays

Pattern over 90 days suggests targeted documentation review. Defensibility hinges on ASAM dimensional notes and concurrent review records. Three charts already missing required elements.

Owner: Compliance + UR
High
Provider enrollment gap, two facilities, three clinicians

Three clinicians at Facilities B and D have started seeing Cardinal Care members before plan-level enrollment effective dates. Retro-enrollment may be possible for some plans; $96K in monthly denials at risk.

Owner: Credentialing
Medium
Treatment plan not updated on 6 closed episodes

Billing services not represented in active treatment plan. Lower SIU exposure but creates appeal-time vulnerabilities and post-pay review risk.

Owner: Clinical leadership
Medium
Late-signed group counseling notes

Signature timing pattern at one facility exceeds 72 hours on group sessions. Acceptable for most payers but creates audit-grade evidentiary risk.

Owner: Clinical ops

Operating recommendations

In order of expected impact on the network's net collection rate over the next 90 days.

  1. 1. Close the credentialing gap. Three clinicians, two facilities.

    ~$96K/mo recoverable

    Stand up the provider-payer enrollment matrix. Hold claims pre-submit when provider is not active. Pursue retro-enrollment where the plan allows. This single action protects 30% of monthly denial exposure.

  2. 2. Appeal the H2011 crisis denials. Sentara and Aetna.

    ~$25K recoverable + prevent forward

    Auth-exempt under each payer's policy. Appeal package includes the policy citation and the chart evidence. Build the template once; reuse for future H2011 denials.

  3. 3. Map H0046 to United HC's accepted HCPCS. Stop CO-189.

    ~$18K recoverable + prevent forward

    Update billing rules so that unlisted H0046 is replaced with the payer-accepted code before claim build. Resubmit the 31 affected claims with the correct coding.

  4. 4. Reactivate AR follow-up cadence on the 47–62 day open-at-payer cluster.

    ~$12K recoverable

    Virginia Premier and Sentara claims sitting more than 21 days without touch. Status checks and structured escalation will move most without appeal. Build the SLA into the AR workflow.

  5. 5. Tighten the medical necessity language in admission notes.

    prevention

    14 of 84 sampled charts show weak medical necessity language. Targeted education at the two facilities driving the pattern, plus a documentation template aligned to ASAM dimensions. Lowers the next quarter's denial volume meaningfully.

Assumption

If the last 30 days are representative

The figures above are real 30-day numbers from the synthetic dataset. Projected across a year (monthly × 12, an assumption that one month is typical), denials beyond write-off run about $3.83M, with the high-confidence recoverable pool near $1.28M and credentialing alone close to $1.73M. A 12-month export would confirm whether this month is representative; we recommend pulling it before relying on the annual figure.
