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.

Coverage and Medical Necessity Criteria

Coverage Criteria for High Complexity E/M Codes

Covered when ALL of the following are met:

E/M code billed must reflect the services provided and documented; follow CPT definitions and AMA/CMS guidance for code selection (MDM or time).

ONE of the following must support level selection

Level selection based on Medical Decision Making (MDM): documentation demonstrates two of three MDM elements at the required level (number/complexity of problems, amount/complexity of data, and risk of complications/morbidity/mortality).
Level selection based on time: total billing practitioner time on the date of encounter meets or exceeds the CPT-listed minutes for the selected code (time includes non-face-to-face work that requires practitioner expertise and excludes travel).

To qualify for high-complexity MDM, documentation must show at least two of the following at a high level: an extensive number of diagnoses or management options reviewed; an extensive amount and/or complexity of data reviewed; high risk of complications and/or morbidity and mortality.

When using time to select the code, the practitioner’s total time on the date of the encounter must meet or exceed the time threshold associated with the CPT code billed.

Medical record must be intelligible, concise, support medical necessity and the level billed, complete, and authenticated (signed) by the author prior to claim submission.

Insufficient documentation or failure to meet the stated MDM or time requirements may result in claim payment delays, disallowance, requests for additional information, or post-payment medical record review.

This policy applies across settings including office/outpatient, hospital inpatient and observation, emergency department, nursing facility, domiciliary, home/residence, and consultations.

Be aware of audit risk: OIG found a substantial portion of Medicare claims were billed at higher intensity than documentation supported, indicating increased scrutiny for high-intensity E/M services.

Applicability and precedence

Coverage and payment determinations are subject to plan documents and applicable law; where conflicts exist, program-specific requirements take precedence.

Payment and coverage under this policy are subject to the member’s certificate of coverage, contract/policy terms, and plan-level administrative policies and procedures.

This payment policy does not constitute medical advice or a contract guarantee; providers retain professional judgment and are independent contractors responsible for treatment decisions.

If state Medicaid coverage provisions conflict with this payment policy, the state Medicaid provisions take precedence; consult the applicable state Medicaid manual for details.

For Medicare members, applicable Medicare National Coverage Determinations (NCDs) and Local Coverage Determinations (LCDs) take precedence; review relevant NCDs/LCDs prior to applying this policy.

If the effective date of this payment policy conflicts with legal or regulatory requirements, law and regulation govern. Health Plan may change, amend, or withdraw this policy as needed.

Time thresholds for office visits — map codes to their associated total time thresholds for new and established patients

99202-99205New patient E/M codes mapped to total time thresholds: 99202 = 15 min; 99203 = 30 min; 99204 = 45 min; 99205 = 60 min

99211-99215Established patient E/M codes mapped to total time thresholds: 99211 = typically 5 min; 99212 = 10 min; 99213 = 20 min; 99214 = 30 min; 99215 = 40 min

Documentation, Authentication, and Provider Responsibilities

Documentation Required

Documentation and Authentication Requirements

Providers billing high-intensity E/M services must document medical necessity and the clinical factors that support the billed level of service. Documentation should demonstrate one or more of the following as applicable: an extensive number of diagnoses or management options reviewed; an extensive amount and/or complexity of clinical data reviewed; and/or a high risk of complications, morbidity, or mortality that justified the service intensity. Failure to provide adequate documentation may result in delayed payment, denial or disallowance of payment pending additional information, or selection of the claim for post-payment medical record review.

Supports billed E/M level: document clinical findings, decision making rationale, and work performed.
Data reviewed: include records, test results, imaging, medication lists, and external records reviewed.
Risk: document factors that increased risk of complications, morbidity, or mortality and how that affected management.

Documentation Required

Medical Record Authentication

All medical records must be authenticated by the author of the record prior to claim submission. Signatures must be handwritten or electronic and clearly identify the author. Incomplete, unsigned, or unauthenticated records may lead to delays, denials, or post-payment review requests.

Medical record signature: handwritten or electronic by the author.
Records must be signed prior to submission of the claim.
Unsigned or unauthenticated records risk payment disallowance or post-payment review.

Denial Risk

Provider Responsibilities and Payment Determination

Providers are responsible for exercising professional judgment in determining medically necessary treatment and the appropriate level of service to bill. Payment determinations are made by the health plan based on submitted documentation, applicable coding and billing rules, and the member's coverage. The Health Plan may request additional documentation to support medical necessity and may adjust or deny payment if documentation does not substantiate the billed service.

Provider responsibility: determine and document appropriate treatment and E/M level.
Payment caveat: payment is subject to review against plan terms, coding rules, and submitted documentation.
Administrative actions: claims may be adjusted, denied, or selected for post-payment review if documentation is insufficient.
