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.

When multiple procedure reductions apply

Rules determining when multiple procedure reductions are applied to billed services by the same individual or same provider group on the same day.

ALL of the following

Two or more procedure codes subject to multiple procedure reductions are billed for the same patient, same date of service, by the same individual physician or other qualified health care professional (same TIN).
If two codes are billed but only one is subject to reduction, no reduction is applied and both codes reimbursed at 100%.
Multiple units of a single reducible CPT code (e.g., CPT 11300 x3) are treated as multiple procedures: reductions apply to second and subsequent units.
In facility places of service (POS list provided), ranking uses CMS Facility Total RVUs; elsewhere use CMS Non-Facility RVUs.
Services that are components or incidental to a primary procedure are not separately billable and are not treated as separate multiple procedures.

Ranking and reductions

How services are ranked and percentage reductions applied.

ALL of the following

Procedures are ranked by applicable RVU (facility or non-facility) from highest (primary) to lowest (secondary/subsequent).
Standard reductions example: primary reimbursed at 100%, secondary at 50% (examples in Q&A).
Codes without CMS-assigned RVUs (gap-fill/0.00 RVU codes) are included in ranking (not excluded).
For certain codes with modifiers 26, 53, or TC, CMS-assigned RVUs for those modifiers are used to determine ranking.

Endoscopic Adjustment Rule

Special rules when multiple related endoscopic procedures within the same family are performed same day.

ALL of the following

Within the same endoscopic family (same Endoscopic Base Code), the Endoscopic Base Code is not separately reimbursed.
Pay full value of the highest valued endoscopy plus the difference between the next highest endoscopy and the Endoscopic Base Code for lower ranked endoscopies.
Multiple endoscopies in same family performed with other reducible procedures are treated as a single 'family' (family adjusted RVU) for ranking against other procedures.
If endoscopies are from different families, endoscopic adjustment does not apply; standard multiple procedure reductions are used for lower RVU endoscopies.

Modifiers and special participants

How assistant, co-surgeon, and team surgeon services are handled relative to multiple procedure rules.

ALL of the following

Multiple procedure reductions do not apply to time-based anesthesia management services.
Assistant surgeon services (modifiers 80,81,82,AS) are ranked collectively among assistant services reported by the same individual and are ranked separately from primary surgeon services.
Co-surgeon/team surgeon services (modifiers 62,66) are ranked separately and independently of primary surgeon or other co-surgeons; reductions apply based on reported co-surgeon/team modifier.
Services reported by the same individual in two capacities (surgeon and assistant) form two separate ranking groups (surgeon group and assistant surgeon group).

What Providers Must Do

Billing Rule

Rank procedures using CMS RVUs

Use CMS RVU values to rank procedures: when services are performed in a facility place of service, rank procedures using the CMS Facility Total RVUs; for services performed in non‑facility settings, rank procedures using the CMS Non‑Facility RVUs. The ranking determines which procedure is primary (full payment) versus secondary/subsequent (subject to multiple procedure reductions).

Facility POS list used for Facility Total RVU ranking: 19, 21, 22, 23, 24, 26, 31, 34, 41, 42, 51, 52, 53, 56, 61; elsewhere use Non‑Facility RVUs (see policy Table of POS values).
Ranking outcome directly impacts primary vs secondary determination and resulting multiple procedure payment reductions.

Billing Rule

Apply Endoscopic Adjustment for same-family endoscopies

When two or more endoscopic procedures within the same endoscopic family (same Endoscopic Base Code) are performed the Endoscopic Adjustment Rule applies: reimburse the highest valued endoscopy at 100% and adjust payment for lower ranked endoscopies by paying the difference between the lower endoscopy and the Endoscopic Base Code; the Endoscopic Base Code itself is not separately reimbursed.

Example affected CPTs: 45378 (Endoscopic Base Code — colonoscopy, diagnostic), 45380 (colonoscopy with biopsy), 45385 (colonoscopy with removal by snare).

Billing Rule

Separate ranking groups for modifier-based roles

Assistant surgeon, co‑surgeon/team surgeon, and primary surgeon services are ranked in separate groups by reported role: assistant surgeon services (modifiers 80, 81, 82, AS) are ranked collectively and separately from primary surgeon services; co‑surgeon/team surgeon services (modifiers 62, 66) are ranked separately and independently. If the same individual reports services in multiple roles, each role forms its own ranking group.

Modifier codes for these separate groups: 62, 66, 80, 81, 82, AS.
When one individual reports multiple roles (e.g., surgeon and assistant), their services form two separate ranking groups (surgeon group and assistant surgeon group) and are ranked independently.

Documentation Required

Submit accurate claims using CMS coding guidelines

Providers are responsible for submitting accurate claims; UnitedHealthcare Medicare Advantage uses CPT, CMS, and other coding guidance and may exercise reasonable discretion in interpreting and applying this policy. Verify coverage specifics in the enrollee's benefit documents.

Check the member's benefit coverage documents or call the customer service number on the back of the member ID card for enrollee‑specific coverage details.

Policy Scope and Context

This policy defines UnitedHealthcare Medicare Advantage reimbursement rules for multiple procedures and the Endoscopic Adjustment when services are billed on CMS 1500 forms (or the electronic equivalent). It applies to all UnitedHealthcare Medicare Advantage products and to all network physicians and other qualified health care professionals submitting claims on the CMS 1500 form. Providers are responsible for submitting accurate claims and UnitedHealthcare Medicare Advantage follows CPT, CMS and other coding guidance when applying this policy, using reasonable discretion where needed.

UnitedHealthcare Medicare Advantage requires that procedures be ranked using CMS National Physician Fee Schedule Relative Value Units (RVUs). When services are performed in a facility setting the policy uses CMS Facility Total RVUs for ranking; for services performed outside the listed facility places of service the policy uses CMS Non‑Facility Total RVUs. The policy lists the facility POS values used for determining when Facility RVUs apply: 19, 21, 22, 23, 24, 26, 31, 34, 41, 42, 51, 52, 53, 56, and 61.

The policy references CMS source material for methodology and implementation, including the CMS PFS Relative Value Files and the Medicare Claims Processing Manual, Chapter 12 (sections cited), and notes administrative updates to Application, Resource, and History sections on 4/1/2023, 4/1/2024 and 4/1/2025.
