Overview
When a claim is submitted, Yuzu evaluates the services billed and assigns them to the appropriate benefit categories under the member's plan.
A single claim can contain multiple service lines, each representing an individual billed service, typically identified by a CPT/HCPCS or revenue code. Each service line can be assigned a different benefit category.
The assigned benefit category determines which coverage rules, cost sharing, and visit limits apply to that service. Benefit categories are determined by more than just the procedure code. Yuzu also evaluates the diagnosis, provider specialty, place of service, revenue code, and other claim details.
Institutional vs. Professional Claims
Claims generally fall into two categories:
Professional claims (CMS-1500 / 837P): Services billed by individual providers, such as physicians, therapists, and specialists
Institutional claims (UB-04 / 837I): Services billed by facilities, such as hospitals, inpatient facilities, and outpatient departments
The type of claim matters because the diagnosis and service information available for matching may differ. For institutional claims, the principal diagnosis typically describes the main reason for the patient's admission or encounter. For professional claims, the relevant diagnosis may be determined using the diagnosis associated with the service line.
When matching, Yuzu considers the claim's principal diagnosis together with any diagnoses on each service line. So the difference between institutional and professional matching is usually a matter of which diagnosis fields the biller populated, not different matching logic.
Example: A patient is admitted for pneumonia and receives laboratory testing during their stay.
The hospital's institutional claim lists pneumonia as the principal diagnosis
A separate professional claim from a physician may contain its own service-specific diagnosis
Although both claims relate to the same hospital stay, they may be assigned different benefit categories based on their billing information and applicable matching rules
Specialist vs. Primary Care Visits
Whether an office visit is classified as Primary Care or Specialist Visit generally depends on the provider's taxonomy code, which identifies their specialty. Two providers can bill the same CPT code but have different benefit categories based on their taxonomy and other applicable matching rules.
Place of Service and Revenue Codes
Where a service takes place can also affect which benefit category applies. Two visits involving similar care may be classified differently depending on whether they occur in a physician's office, urgent care center, emergency room, or hospital outpatient department.
Institutional claims may also use revenue codes to identify the type of facility service.
These codes help Yuzu distinguish between different care settings and determine which benefit category applies.
Why Similar Visits May Have Different Benefits
A service's CPT code alone does not guarantee that the same benefit will apply every time. Benefit classification can depend on a combination of factors:
Location: Office vs. hospital outpatient vs. emergency department
Provider: PCP vs. specialist vs. therapist
Diagnosis: Preventive vs. diagnostic, or rehabilitation vs. habilitation
Procedure: The actual CPT/HCPCS or revenue code billed, including modifiers
Claim details: Facility type, admit type, DRG/ICD-10-PCS on inpatient claims, claim billed amount
Member: Age and sex (e.g., age-banded or sex-specific preventive benefits)
For example, a patient visits their PCP for an annual wellness exam. Preventive Care may apply when the procedure and diagnosis meet the plan's preventive criteria.
If the patient returns, the visit may instead fall under Primary Care. Even when the office location and provider are identical, the diagnosis and procedure information can change the assigned benefit.
Yuzu evaluates the applicable matching rules and selects the highest-priority rule that matches the service line.
Visit Limits and What Counts as a Visit
Some benefit categories have limits on the number of covered visits within a plan year, including preventive care, rehabilitation, and habilitation services.
Yuzu generally counts visits by unique dates of service, rather than the number of service lines or claims submitted. Multiple services performed on the same date typically count as one visit toward the applicable benefit limit. Only approved services with an allowed amount count toward a limit.
For ER and inpatient services, visits are counted by encounter rather than by date, so a facility claim and a physician claim for the same ER visit count as one visit. Separately billed professional readings also do not count as additional visits when a corresponding institutional service in the same benefit category exists within seven days.
Shared Limits
Multiple benefit categories can share one visit limit. For example, a plan may set a single combined limit for PT, OT, and ST, or for rehabilitation and habilitation together. When categories share a limit, a visit in any of them counts against the same cap. This is the most common reason a member appears to hit a limit early.
When a Limit is Exceeded
The outcome depends on how the limit is configured:
Standard visit limits: Services past the limit are denied
Diagnosis-grouped limits (common for preventive benefits): If a limit tied to a specific diagnosis is exceeded, such as a second annual wellness visit, the service is processed under another applicable benefit category instead of denying. That category's cost sharing applies. The line shows the PEX remark code. If no other category applies, the service may be denied
Diagnosis-Driven Benefit Categories and Exclusions
Certain benefit categories and exclusions depend on the diagnosis code associated with the service, not just the procedure code.
The diagnosis helps determine the purpose of the service and which benefit category applies. This is particularly relevant when distinguishing between maternity and surgical care, fertility-related services, and routine vs. medical eye care.
A service may also match both a covered benefit and an exclusion. When a service line matches an exclusion, the exclusion always takes priority over a matching benefit category, regardless of how the two rules are weighted. Among benefit categories themselves, the highest weighted matching rule wins.
Emergency Out-of-Network at In-Network Cost Sharing
Emergency services have special protections under the No Surprises Act (NSA). For qualifying emergency services, members generally cannot be charged higher out-of-network cost sharing solely because the emergency provider or facility is OON.
As a result, an emergency claim may be processed using in-network cost sharing even when the provider is not actually part of the network.
