Insurance Coverage Summary

Overview

Pull Coverage and Organization resources to produce a consolidated insurance summary. Identify primary and secondary coverage, extract plan details, policy and group numbers, coverage periods, and payor organizations. Flag expired coverage, missing authorization data, coverage gaps, and coordination of benefits issues. Output a structured summary suitable for front-desk verification, prior authorization workflows, or care coordination.

FHIR Resources Used

Instructions

Step 1: Pull All Coverage Resources

Tool: fhir_search
resourceType: "Coverage"
queryParams: "patient=[patient-id]"

Retrieve all Coverage resources regardless of status to capture full history. For each entry extract:

• status: active, cancelled, draft, entered-in-error
• type: Coverage type from type.coding (system http://terminology.hl7.org/CodeSystem/v3-ActCode)
• policyHolder: Reference to the policyholder (may be Patient, RelatedPerson, or Organization)
• subscriber: Reference to the subscriber
• subscriberId: Subscriber ID / Member ID
• beneficiary: Reference to the patient
• dependent: Dependent number
• relationship: Subscriber-to-beneficiary relationship (self, spouse, child, other)
• period: Coverage effective period (start and end dates)
• payor: Reference to the insurance Organization
• class[]: Coverage classification array, each with:
  • type.coding.code: "group", "subgroup", "plan", "subplan", "class", "subclass", "sequence", "rxbin", "rxpcn", "rxid", "rxgroup"
  • value: The identifier value
  • name: Human-readable name
• order: Coverage order (1 = primary, 2 = secondary, 3 = tertiary)
• network: Network name or identifier
• costToBeneficiary[]: Copay and coinsurance information
  • type.coding.code: "copay", "coinsurance", "deductible"
  • valueMoney or valueQuantity

Step 2: Resolve Payor Organizations

For each Coverage resource, resolve the payor reference:

Tool: fhir_read
resourceType: "Organization"
id: "[payor-reference-id]"

Extract from the Organization:

• name: Insurance company name
• telecom: Phone number, website
• address: Mailing address
• identifier: NPI, Tax ID, payer ID
• type: Insurance company type classification

Step 3: Determine Coverage Hierarchy

Establish primary vs secondary coverage:

1. Use Coverage.order field if populated (1 = primary, 2 = secondary)
2. If order is absent, apply coordination of benefits rules:
   • Self-employed / Individual: The patient's own employer plan is primary
   • Spouse coverage: Apply Birthday Rule for dependent children (plan of parent whose birthday falls earlier in calendar year is primary)
   • Medicare: Medicare is primary when patient is 65+ with no employer group health plan (EGHP) for 20+ employees. Medicare is secondary when patient has EGHP coverage.
   • Medicaid: Almost always secondary (payer of last resort)
   • Workers' Compensation: Primary for work-related injuries/illnesses
   • Auto Insurance / Liability: Primary for accident-related claims

Step 4: Validate Coverage Status

For each Coverage resource, check:

Active Coverage Validation:

• status = "active"
• period.start <= today
• period.end is null OR period.end >= today
• subscriberId is populated
• payor reference resolves to a valid Organization

Flag: Expired Coverage

• period.end < today but status still = "active"
• Flag: "Coverage [plan name] has end date [date] in the past but status is still active. Verify with payor."

Flag: Missing Subscriber ID

• subscriberId is null or empty
• Flag: "Coverage [plan name] is missing subscriber/member ID. Required for claims submission."

Flag: Missing Group Number

• No class entry with type = "group"
• Flag: "Coverage [plan name] is missing group number."

Flag: No Primary Coverage

• Zero Coverage resources with order = 1 or no active coverage at all
• Flag: "No primary insurance coverage identified. Verify coverage status with patient."

Flag: Dual Coverage Without Coordination

• Multiple active coverages but order field not set on any
• Flag: "Multiple active coverages found but primary/secondary order not specified. Coordination of benefits determination required."

Step 5: Extract Benefit Details (If Available)

Check for cost-to-beneficiary information:

• Copay amounts per visit type
• Coinsurance percentages
• Deductible amounts (individual and family)
• Out-of-pocket maximum

Note: Most FHIR servers do not populate costToBeneficiary in Coverage resources. If absent, note: "Benefit details not available in FHIR record. Verify with payor or eligibility check system."

Step 6: Check for Related Authorization References

Tool: fhir_search
resourceType: "Claim"
queryParams: "patient=[patient-id]&status=active&_count=5&_sort=-created"

If Claim resources are available, check for:

• insurance[].coverage: References to Coverage resources
• insurance[].preAuthRef: Prior authorization numbers
• insurance[].focal: Which coverage is primary for this claim

If no Claim resources, skip this step.

    - Self-pay / uninsured patient
    - Coverage data not yet entered
    - Coverage stored in a different system not connected to this FHIR server

RECOMMENDATION
==============
1. Verify insurance status with patient
2. Check if coverage is documented in the practice management system
3. Screen for Medicaid/marketplace eligibility if uninsured
4. Document self-pay status if confirmed uninsured

Troubleshooting

Coverage Resources Lack Class Details (No Plan Name, No Group Number)

• Some EHR systems store minimal coverage data. The class array may be empty.
• Check type field for coverage type (HMO, PPO, Medicare, Medicaid).
• Resolve the payor Organization reference -- the organization name may be the only plan identifier available.
• For EPIC systems, coverage details may be in extensions rather than standard class elements.

Multiple Coverage Resources With Same Payor

• This can happen when coverage is renewed annually and each period creates a new Coverage resource.
• Deduplicate by checking period overlap. The most recent non-expired Coverage is the current one.
• If periods overlap with the same payor and plan, take the one with the later period.start.

Coverage.order Not Populated

• Many FHIR servers do not populate the order field.
• Apply coordination of benefits rules from Step 3 to determine primary vs secondary.
• If determination is ambiguous, flag for manual review: "Unable to determine primary vs secondary coverage programmatically. Manual coordination of benefits determination required."
