We build clean claims, run payer-specific scrubbing beyond standard clearinghouse edits, submit the ANSI 837P within 24 hours of charge entry, monitor the 277CA acknowledgment before end of business, and correct any rejection before it ages into a timely filing problem.

A cardiology group near the Houston Medical Center submitted a claim for a cardiac catheterization under CPT 93458. The documentation was clinically complete. The procedure was medically necessary. The claim hit UnitedHealthcare’s automated adjudication system at 9:18 a.m. By 9:19 a.m. — 1.2 seconds of automated review — it was denied. Not because the procedure was wrong. Because the ejection fraction language didn’t match the keyword pattern UHC’s system flags as required.
The AMA’s 2025 Prior Authorization Physician Survey found that 61% of physicians say payer AI is increasing denial rates. In-network denials are averaging 19% in 2026, out-of-network at 37%, per Droidal’s 2026 analysis.
What this means for your submission: Payer AI executes pattern matching, not clinical judgment. The documentation language in your claim, the exact wording of medical necessity, the specificity of ICD-10 codes — these determine whether the algorithm passes or flags the claim before a human reviewer sees it.

Every competitor uses these words interchangeably. They are not the same thing. Treating them identically produces the wrong workflow response and leaves recoverable revenue uncorrected.
A rejection occurs when the clearinghouse or payer's front-end system identifies a technical error before the claim enters adjudication. Rejections return through the 277CA acknowledgment — typically within hours. Because it was never formally received by the payer, it can be corrected and resubmitted without consuming the timely filing window. It is a pre-adjudication technical failure. Correctable, same day, if someone is monitoring the 277CA.
A denial occurs after the payer has formally received and reviewed the claim. Denied claims are subject to the payer's timely filing and appeal deadlines and require a different correction workflow. Denial reason codes in the CO and PR series appear on the Explanation of Benefits or Electronic Remittance Advice. A denial not appealed within the payer's window is revenue permanently written off.
Why this matters in practice: A rejected claim caught within the same business day through 277CA monitoring can be corrected and resubmitted with no financial consequence. That same claim sitting unworked for three weeks has consumed a third of a 90-day commercial payer's timely filing window before it ever reached adjudication. Practices running end-of-month rejection reports routinely lose four to six weeks of timely filing window every billing cycle. We monitor 277CA responses within two hours of each batch transmission.
Your clinical team charges encounters the way it always has. The process change is entirely on the billing side — charges are intercepted before they become error-laden claims, scrubbed before submission, and worked same day if anything is flagged.
Charges entered into your EHR by the daily cut-off are reviewed for fee schedule accuracy, CPT code completeness, diagnosis specificity, and documentation alignment. Claims are built with diagnoses sequenced for medical necessity support, CPT codes checked against the current NCCI edit table, and modifiers applied where payer-specific rules require them.
Every claim runs two scrubbing passes. First: clearinghouse-level scrubbing against HIPAA transaction standards, federal code pair edits, Medically Unlikely Edits, and demographic format requirements. Second: our payer-specific rule layer, which applies each contracted payer’s individual billing policies that exist outside the standard clearinghouse edit set. A claim failing either layer enters same-day correction before any submission occurs.
Clean claims are formatted as ANSI 837P transactions and transmitted within 24 hours of charge entry. Every batch generates a 999 functional acknowledgment. We review 277CA claim acknowledgment responses within two hours of batch transmission. A claim submitted at noon and rejected by 12:45 p.m. is corrected and resubmitted by 3:30 p.m. — not discovered in the next monthly report.
Claims passing the 277CA are tracked at fixed intervals — 14 days for commercial claims, 7 days for Medicare — through the payer’s claim status system. Claims approaching timely filing limits in any payer’s queue are escalated to priority follow-up regardless of elapsed time. We track payer-specific timely filing windows for every contracted plan and flag claims at risk 14 days before the deadline.
Claims returning as denials enter the denial management workflow within 72 hours of the ERA posting. Denial reason codes are reviewed, the root cause is identified at the specific claim level, and the claim is either corrected and resubmitted or flagged for formal appeal depending on the denial type. Revenue recovery does not wait for the end of the month.
A claim doesn’t become clean at the moment of submission. It becomes clean through a sequence of validation, scrubbing, and correction steps that happen before the 837P transaction leaves your system. Most practices skip two to four of these.
Every charge is reviewed against the practice's fee schedule and the payer's contracted rate before the claim is built. Unbundled charges, missing charges, or services entered at the wrong billing level are corrected before the claim is constructed — not after the ERA comes back short.
Diagnosis codes are reviewed for highest specificity and correct sequencing. The primary diagnosis must support medical necessity for the primary procedure. Incorrect sequencing — where a secondary diagnosis appears in the primary position — creates a medical necessity challenge that is entirely preventable at the charge review stage.
Every CPT code combination is checked against the current NCCI edit table before the claim is built. When a modifier is needed to override an edit, it is applied with documentation that supports the modifier use — modifier 59, or the X-modifier family for more specific distinct service circumstances.
Standard clearinghouse scrubbing checks against universal HIPAA standards only. We maintain payer-specific rule libraries updated quarterly from payer policy bulletins — covering UnitedHealthcare, Aetna, and all BCBS plan variants — and apply those rules to every claim before submission.
Patient demographics — name spelling, date of birth, member ID, group number, plan effective date — are verified against the real-time eligibility response before the claim is built. Demographic mismatches are the single most preventable category of claim rejection.
Claims approaching timely filing limits in any payer's adjudication queue are escalated to priority follow-up regardless of how much elapsed time remains. Claims that return as denials enter the denial management workflow within 72 hours of the ERA posting — not at the end of the month.
Generic claim submission processes apply one scrubbing ruleset to every specialty. We apply the right one to each — CPT-specific modifier rules, payer policies, and specialty-specific NCCI edit combinations that a generalist process produces systematic denials from.
Time-based CPT 90832/90834/90837 documentation thresholds, add-on code 90833 companion pairing rules, and behavioral health carve-out administrator billing policies that differ materially from the medical plan — serving BCBS and Cigna patients in Chicago and Los Angeles.

Our payer-specific rule library covers billing policies for all major payers — UnitedHealthcare, Aetna, Cigna, Humana, and all BCBS plans — across specialties not listed. Contact us to discuss your specific specialty's claim submission requirements and denial patterns.
Hierarchical Condition Category coding — HCC coding — is the risk adjustment methodology that Medicare Advantage plans use to calculate risk-adjusted payments to their contracted providers. Conditions mapped to HCC codes must be documented and coded on a claim for each Medicare Advantage patient in each plan year to maintain accurate risk scores and generate appropriate reimbursement.
Medicare Advantage now covers more than 50% of all Medicare beneficiaries in many US markets. For primary care practices in Chicago’s Lincoln Park and Gold Coast neighborhoods, internal medicine groups near the Houston Medical Center, and geriatric specialists in Phoenix’s Scottsdale corridor, the quality of HCC coding on submitted claims directly affects risk score calculation for each patient.
An HCC-eligible condition appearing in the clinical documentation but not coded on the submitted claim represents both a documentation gap and a payment gap. The claim processes without error. The revenue is simply lower than the clinical encounter supports.
Our claim review process for Medicare Advantage patients includes an HCC coding audit step. We cross-reference the active problem list and clinical encounter notes against submitted diagnosis codes to identify any chronic conditions documented but omitted from the claim. We do not modify clinical documentation. We ensure the submitted claim captures the full diagnostic picture the clinical encounter already contains.

Our previous billing company was submitting through standard clearinghouse scrubbing only. We had a recurring denial pattern from Aetna on a specific E/M plus procedure combination that was passing every clearinghouse edit and failing Aetna’s payer-specific bundling policy. QlaimPro identified the Aetna policy in the first week of our claims audit and built it into their scrubbing layer. That denial category went to zero within 30 days.
RCM Director | Internal Medicine Group, 6 providers
We had no idea 277CA rejections were operationally different from denial EOBs. Our previous biller ran rejection reports monthly. QlaimPro showed us that claims were sitting rejected at the clearinghouse for 30 to 45 days without being worked. That is a third of our commercial payer timely filing window consumed before the claim reached the payer. Rejections are now corrected the same day.
Practice Administrator | Pain Management, 3 physicians
We had a systematic NCCI edit violation in our surgical assistant billing that was producing denials on every case involving an assistant surgeon. Nobody had caught it for eight months. QlaimPro’s claims audit identified the modifier error in the first claims review. They corrected it going forward and filed corrected claims on every case within the timely filing window.
Billing Manager | Orthopedic Group, 5 surgeons
We connect to more than 40 EHR and practice management systems. Charges flow from your EHR into our claim-building workflow. Claim status updates, denial codes, and ERA payment data post back through the same connection. No manual data transfer. No parallel entry in a second platform.
Claims route through the payer’s preferred submission pathway. We monitor all acknowledgment pathways — not just clearinghouse-standard ones.
Primary clearinghouse
Secondary clearinghouse
Tertiary clearinghouse
Direct payer portal connections are used where payer-specific submission rules require routing outside the standard clearinghouse pathway. These connections generate payer-specific acknowledgment formats — all monitored, same as 277CA responses.
Every claim that fails first-pass submission requires correction, resubmission, and tracking — administrative work that generates no additional revenue while consuming staff time. The HFMA benchmarks rework at $25–$30 per claim.
HFMA benchmarks the cost per reworked claim at $25–$30 in an outpatient medical practice, including staff time, system costs, and payment delay penalties. A practice submitting 500 claims/month with a 90% clean claim rate reworks 50 claims monthly at $1,250 in administrative cost.
A claim denied on first submission and corrected within the same week still delays payment by a full payer processing cycle — typically 14 to 30 additional days. A practice with 200 claims/month at 10% denial rate delays payment on 20 claims by an average of 21 additional days at $350 average claim value.
An experienced medical biller with claim submission, NCCI edit management, and clearinghouse monitoring skills earns $42,000–$58,000 annually. MGMA replacement cost benchmarks for billing roles sit at $10,000–$14,000 per departure. When that person leaves, the clean claim rate typically drops during the 60–90 day competency ramp of their replacement.
Every answer here is complete. You should not need a phone call to understand what you are evaluating.
A clean claim is a medical billing claim accepted by the payer on the first submission without rejection, error, or request for additional information. It contains accurate demographic data, correct CPT and ICD-10 codes, appropriate modifiers, medical necessity support through diagnosis sequencing, and compliance with the payer’s billing rules and national edit standards. The HFMA defines a target of 98% or higher for a well-functioning revenue cycle. In practice, many organizations operate in the 85–95% range.
A claim rejection occurs before the claim enters payer adjudication. It returns through the 277CA acknowledgment and can be corrected and resubmitted without consuming the timely filing period. A claim denial occurs after the payer has formally received and reviewed the claim. Denials appear on the Explanation of Benefits or ERA with CO or PR reason codes and are subject to the payer’s appeal deadline. The workflows, timely filing implications, and correction approaches are fundamentally different. Treating them as the same problem produces incorrect responses.
The 277CA is the Claim Acknowledgment transaction in the ANSI X12 5010 EDI standard. After a batch of 837P claim files is transmitted to a clearinghouse or payer, the 277CA reports whether each individual claim was accepted for adjudication or rejected for a technical error. Practices not systematically monitoring 277CA responses miss clearinghouse-level rejections that never reach the payer at all — those rejections age silently against the timely filing window until someone runs a rejection report days or weeks later. The 277CA should be reviewed within hours of each batch transmission, not at month end.
NCCI stands for National Correct Coding Initiative. CMS publishes and quarterly updates two categories of edits: Procedure-to-Procedure edits identify CPT code pairs that cannot be billed together on the same date without a supporting modifier (59 or the X-modifier family). Medically Unlikely Edits limit the maximum units billable for a specific procedure on a single date. An NCCI edit violation submitted without the correct supporting modifier is an automatic denial. Commercial payers have broadly adopted NCCI edits, so compliance affects Medicare, Medicaid, and most commercial claims simultaneously.
Hierarchical Condition Category coding is the risk adjustment methodology Medicare Advantage plans use to calculate risk-adjusted payments for enrolled beneficiaries. Conditions mapped to HCC categories must be coded on the claim for each Medicare Advantage patient in each plan year for the plan to receive accurate risk-adjusted payment. An HCC-eligible chronic condition documented in the clinical notes but not coded on the submitted claim represents revenue the clinical work earned but the billing process did not capture. Our claim review process includes an HCC audit step for Medicare Advantage patients.
Outsourced claim submission is typically priced as a percentage of collections, a per-claim fee, or as part of a full RCM engagement. Per-claim pricing for clean claim submission ranges from $1.50–$4.00 per claim depending on specialty complexity, payer mix, and whether scope includes payer-specific scrubbing, 277CA monitoring, and denial routing. The cost comparison against in-house submission should include the full salary and benefits of billing staff, MGMA’s documented replacement cost of $10,000–$14,000 per departure, and the HFMA’s benchmark of $25–$30 per reworked claim.
When a claim misses the payer’s timely filing deadline, the payer denies it as untimely — a denial that is generally not appealable. Unlike medical necessity or coding denials, timely filing denials cannot be overturned by providing additional documentation or clinical justification. The revenue is permanently lost. Timely filing windows range from 90 days for some commercial plans to 12 months for Medicare. For claims rejected or denied on first submission, the timely filing clock continues running during the correction and resubmission period — which is why same-day rejection correction is not optional.
The ANSI 837P is the electronic data interchange format for submitting professional medical claims. The P designates the professional version, used by physician practices, group practices, and outpatient clinics. The format is maintained under the ANSI X12 5010A1 standard, mandated by HIPAA for electronic claim transmission. The 837P structures all required claim elements — patient demographics, provider identifiers including NPI and TIN, dates and place of service, diagnosis codes, procedure codes, modifiers, and billed amounts — into a standardized electronic file that clearinghouses and payers process automatically.
We review your last 60 days of claim submission data — clearinghouse rejection reports, denial EOBs, and ERA payment records — and produce a written audit in 7 days. The audit tells you where your revenue is leaking and how much.
