ClaimsXten Edit Criteria & Triggers

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Claims-edit denial/recommendation criteria

Claim lines are denied or recommended for denial when any of the following automated rule conditions are met:

ANY of the following

ALL of the following
- ALL of the following
  - ALL of the following
    ALL of the following
    Surgical inclusive: Denies claim lines containing supplies when billed for the same date of service as a surgical procedure for which Centers for Medicare and Medicaid has assigned a global period.
    Denies supplies billed same date as a procedure with a CMS-assigned global period (surgical inclusive).
    Incidental/component: Denies a claim line clinically integral to accomplishing the principal procedure/service or considered a component of the more comprehensive procedure.
    Multicode rebundle: Denies a claim line when two or more procedures are used to describe a service when a single, more comprehensive procedure exists that more accurately describes the complete service performed.
    Mutually exclusive: Denies a claim line that would not reasonably be performed on the same patient on the same day.
  - Same-day E/M vs procedure (global period): Denies Evaluation and Management codes billed on the same date of service as a procedure code with a global period, and denies E/M codes billed within pre-operative or post-operative global periods.
ALL of the following
- Modifier-to-procedure invalid combinations: Denies or recommends denial for claim lines with invalid modifier-to-procedure combinations, including non-payment modifiers; when multiple modifiers are present all are evaluated and if at least one is invalid the line is recommended for denial.
- Modifier-specific rules: Denies laboratory lines missing required modifiers (-91/-59) when applicable; denies co-surgeon modifier -62 when not supported; denies duplicate bilateral billing when service already billed with -50.
ALL of the following
- MUE and frequency exceedance: Denies when units of service exceed CMS MUE values or when frequency validations indicate a code was submitted more times than allowed per date of service or site.
- CPAP/Bi-level supply frequency: Denies CPAP/Bi-level supply claims when units exceed CMS-recommended replacement frequency.
ALL of the following
- NCCI/CCI bundling and IOCE unbundled pairs: Denies code pairs found in the CMS National Correct Coding Initiative and Integrated Outpatient Code Editor that are not recommended for reimbursement when billed together.
- Facility unbundling and global/component detection: Detects unbundling of surgical codes on facility claims; identifies professional/technical/global component duplicate submissions to prevent overpayment.
ALL of the following
- Add-on code billed without base: Identifies add-on CPT/HCPCS codes billed without required primary/base procedure(s) and recommends denial; includes CMS add-on without base rule for professional and outpatient facility claims.
- CMS add-on facility rule (2024): Identifies add-on codes billed without acceptable supporting primary procedure/base code by the same practitioner for the same patient on the same date of service, per CMS; add-on codes must not be billed as stand-alone.
ALL of the following
- Bilateral services duplicate billing: Identifies when a procedure already billed with modifier -50 is subsequently billed again for the same date of service; denies the second submission.
- Lifetime event limit: Audits and recommends denial when a procedure has been submitted more times than clinically reasonable in a member's lifetime.
ALL of the following
- New patient E/M within three years: Recommends denial of new patient E/M when another E/M or face-to-face professional service was billed by the same provider or group within the prior three years; also addresses submission of subsequent E/Ms lacking required modifier -27.
- Ancillary after non-covered service: Identifies ancillary services billed after a non-covered service and allows ancillary only if another covered service on same day is found.

Coding Edits and Limits

CMS-based coding editsmixedCovered

NCCI pairs	Code pairs found in CMS National Correct Coding Initiative that should be denied when inappropriately billed together
MUEs	Medically Unlikely Edits/MUEs established by CMS to limit units per date of service

Modifier validationModifierCovered

Modifier -50/-27/-62/-59/-91

Modifiers referenced for bilateral services, multiple visits, co-surgeon, lab repeat and visit modifier requirements

Units per date of service (MUE / frequency limits)

Rule triggerExceeds MUE or defined frequency per CPT/HCPCS code (varies by code and setting).

Specific examplesMUEs Multiple Lines — denies when units submitted by same provider/member/date exceed CMS MUEs; Outpatient Facility MUEs — facility-specific MUE enforcement.

Frequency validationsFrequency Validation rules deny when a code is defined as once per date of service or when quantity billed exceeds maximum allowed per date of service/site.

CPAP/Bi-level supply frequencyDenies supply codes for CPAP/Bi-level therapy when units exceed CMS-recommended replacement schedule (see L-codes/LCDs).

Lifetime event limit

DefinitionMaximum times a procedure may be submitted in a member's lifetime varies by procedure and is audited to detect clinically unlikely repeat submissions.

What Providers Need to Do / Watch For

Denial Risk

Automated denial/recommendation actions

Automated claim-edit rules will deny or recommend denial of claim lines when edits detect issues such as global surgery period conflicts; incidental or component services billed with a more comprehensive procedure; multicode rebundling; mutually exclusive procedures; same-day, pre-op, or post-op E/M visits billed with procedures assigned a global period; and invalid modifier-to-procedure combinations (including non-payment modifiers).

Denies supplies billed same date as a procedure with a CMS-assigned global period (Surgical Inclusive).
Denies lines clinically integral to a principal procedure or considered a component of a more comprehensive procedure (Incidental/Component edits).
Denies when two or more procedures are used where a single more comprehensive procedure exists (Multicode Rebundle).
Denies procedures not reasonably performed on the same patient the same day (Mutually Exclusive).
Denies E/M codes billed on the same date or within pre/post-op global periods of a procedure with a global period (Same Day / Pre-Op / Post-Op Visit edits).
Recommends denial for invalid modifier-to-procedure combinations, evaluating all modifiers on a line and flagging non-payment modifiers found inappropriate.

Denial Risk

Claim-type specific denial rules

Some edit rules apply only to specific claim types — for example, CMS-designated 'B' bundled procedures and the Bundled Service rule are applied to professional claims, while CMS Add-on Without Base Code Facility rules target outpatient facility claims when an add-on code is billed without an eligible primary/base code by the same practitioner on the same date of service.

Bundled Service (professional claims): identifies procedures CMS indicates are always bundled (status code indicator 'B') and denies when billed with other procedures.
CMS Add-on Without Base Code Facility (outpatient facility claims): identifies add-on CPT/HCPCS codes billed without acceptable supporting primary/base procedure(s) by the same practitioner for the same patient on the same date of service.

Key Terms

MUE — Medically Unlikely Edit

DefinitionMedically Unlikely Edit (MUE) — an edit that denies claim lines when units of service submitted for a CPT/HCPCS code by the same provider, same member, same date of service exceed the MUEs established by CMS.

ScopeApplies to multiple-lines submissions and includes facility-specific MUE enforcement for outpatient claims.

Effect on claimsClaims exceeding MUE values are denied; rules evaluate units per date of service and may also apply across providers for DME items.

Add-on code

DefinitionAdd-on code — a CPT or HCPCS code that is performed in addition to a primary/base service and must not be reported as a stand-alone code.

Billing constraintIdentified by Add-On Without Base rules; denies or recommends denial when an add-on is billed without its related primary/base procedure for the same patient, same date of service.

Facility vs ProfessionalSeparate rules exist (Add-On Without Base and CMS Add-on Without Base Code Facility) to enforce add-on requirements for facility and professional claim types.

Global period

DefinitionGlobal period — the postoperative/preoperative period assigned by CMS to a procedure during which certain E/M or supply lines may be denied when billed with the global procedure.

Same-day/Pre/Post op editsSame Day Visit, Pre-Op Visit, and Post-Op Visit edits deny E/M codes billed on the same date or within the pre/post-operative period of a procedure with a CMS-assigned global period.

Component detectionGlobal Component and Component Billed rules detect professional/technical/global component duplicate submissions to prevent overpayment across providers during the global period.
