ClaimsXten Automated Edit and Payment Criteria

ClaimsXten automated edit and payment criteria

Automated criteria applied to claim lines:

Edits procedure codes inconsistent with member gender or patient age (gender/age validation).

Edits for non-covered procedures per health plan medical/payment policy (medical policy procedure to place of service).

Unbundling: Edits when a procedure is submitted with a more comprehensive procedure, overlapping procedure, or procedures that are medically impossible/improbable to perform together on the same date of service; may deny component codes when comprehensive code applies.

Add-on codes require defined base code present; deny add-on code lines when associated base code cannot be found for same member/date of service. Also audits that vaccine supply and immune globulin supply codes are submitted with their associated base codes.

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.

Coding, Frequency, and Payment Adjustment Rules

Correct coding and frequency groupsmixedCovered

NCCI pairs	Code pairs that are edited per National Correct Coding Initiative when submitted together
MUE (Medically Unlikely Edits)	Frequency edits defined by CMS for CPT/HCPCS codes

Payment adjustment codesmixedCovered

Multiple Procedure Indicator = 1/2/3	Used to determine pay percent adjustments for multiple procedures per CMS physician fee schedule
Modifier -80/-81/-82/-AS	Assistant surgeon modifiers subject to pay-percent adjustments and potential denial

inv-04: MUE frequency limit

DefinitionExceeds CMS-defined MUE frequency for a CPT/HCPCS code across all claim lines by the same provider for the same member on the same date of service (non-facility).

TriggerApplied when the MUE frequency value for a CPT/HCPCS code is exceeded across all claim lines by the same provider for the same member on the same date of service.

BasisMUEs are frequency edits developed by CMS based on anatomic/clinical considerations.

EffectDenies or edits lines that exceed the defined MUE frequency; intended to prevent clinically unlikely quantities per date/provider/member.

inv-05: Allowed times per date of service

DefinitionMaximum allowed quantity per date of service per site — edits fire when the quantity billed for the procedure code exceeds the maximum allowed per date/site.

Allowed Once FilterEdits codes that should only be performed once per date of service when billed with quantity > 1.

Allowed Multiple Times FilterIdentifies codes when the quantity billed exceeds the maximum allowed per date of service for that site; assigns appropriate duplicate edits when descriptions dictate limits.

EffectAssigns duplicate or quantity-based edits that may deny or reduce payment when allowable per-date limits are exceeded.

Billing Requirements and Provider Impact

Billing Rule

Add-on Without Base Code

Add-on codes (CPT/HCPCS) require the associated base procedure to be billed for the same member on the same date of service. Vaccine supply and immune globulin supply codes must be submitted with their associated base codes; add-on lines without the defined base code may be denied.

Applies to CPT and HCPCS add-on codes with AMA-defined base codes
Vaccine supply and immune globulin supply codes must accompany associated base code submissions

Denial Risk

Pre/Post-Operative and Global Edits

E&M services billed during another procedure's global period — including pre-operative visits, same-day visits, and post-operative visits — may be denied or adjusted. Claims editing will identify E&M codes submitted within the defined pre- and post-operative windows or on the same date of service as a procedure with a global period and apply appropriate denials or payment adjustments per the plan's global surgery and same-day visit rules.

Pre-operative and post-operative periods are evaluated per the surgical/global period definitions
Same-day visit edits apply when an E&M is billed on the same date as a procedure within a global period
Lines may be denied or have payments adjusted based on global period edits

Denial Risk

CPAP/BIPAP Supply Frequency and Modifier Validation

CPAP/BIPAP supply lines submitted more frequently than the allowable interval or without the required KX modifier will be identified and recommended for denial. Supplies submitted prior to the renewal interval, in quantities exceeding usual maximums, or submitted with modifiers EY, GA, or GZ (or without KX when KX is required) may be denied. When KX is present but the submission is prior to the allowed renewal interval, the line may still be denied.

Targets CPAP/BIPAP supply codes submitted at a rate exceeding usual/customary frequency
Denies lines submitted without modifier -KX when policy-required criteria are not met
Recommends denial for supplies submitted prior to the renewal interval even if modifier -KX is present
Identifies submissions with modifiers -EY, -GA, or -GZ for denial review

Key Terms and Edit Definitions

inv-09: Unbundling Rule

DefinitionUnbundling Rule: edits when a procedure is submitted with another procedure that is more comprehensive, overlaps, or is medically impossible to perform concurrently on the same date; component codes may be denied and comprehensive code recommended.

NCCI InteractionWhen a code pair is identified by the National Correct Coding Initiative as not recommended together, the component code is edited per NCCI rules.

RebundlingIf a more comprehensive code exists and is not submitted by the same provider for the same date, the comprehensive code may be added to the claim; if submitted, component codes may be denied.

inv-10: Global Component

DefinitionGLOBAL_COMP (Global Component): audits instances where the sum of all payments (total, professional, technical) across multiple providers for a procedure exceeds the amount that would have been paid for the total procedure for the same member/date.

ScopeAudits across providers for the same member and same date of service to identify overpayment when professional and technical components exceed total procedure payment.

EffectMay adjust or deny payments when aggregated payments exceed the expected total procedure amount.

inv-11: MUE

DefinitionMUE (Medically Unlikely Edits): CMS-defined frequency edits based on clinical and anatomic considerations that limit how often a code is payable per date/provider/member.

ApplicationUsed to detect medically unlikely quantities and enforce frequency limits (applies to MUE multiple lines and MUE frequency across claim lines).

Interaction with Other RulesMUE edits operate alongside frequency validation rules (allowed once/allowed multiple times per date) to determine denials or edits for excessive quantities.

EffectDenies or edits claim lines that exceed CMS-defined MUE values, preventing payment for clinically improbable quantities.
