Member-Provider-Payer Interaction Lifecycle
The healthcare claims lifecycle is a complex, multi-step process involving members (patients), providers (doctors, hospitals), and payers (insurance companies). Understanding this flow is essential for anyone working in health IT, revenue cycle management, or interoperability.
Phase 1: Member → Provider (Pre-Service)
Step 1: Member Seeks Care
The member schedules an appointment with a healthcare provider (PCP, specialist, hospital, urgent care, etc.).
Step 2: Insurance Verification
Before or at check-in, the provider's office verifies the member's insurance coverage:
- EDI 270 — The provider sends an Eligibility Inquiry to the payer
- EDI 271 — The payer responds with an Eligibility Response containing:
- Coverage status (active/inactive)
- Plan details and effective dates
- Copay and deductible amounts
- Prior authorization requirements
- Remaining deductible and out-of-pocket amounts
Step 3: Prior Authorization (if required)
For services requiring pre-approval:
- EDI 278 — Provider submits a Prior Authorization Request
- Payer reviews clinical criteria and responds with approval, denial, or pend
- Under CMS's new FHIR mandates, this will transition to Da Vinci PAS (FHIR-based prior auth)
Step 4: Service Delivery
The provider delivers the medical service — office visit, surgery, diagnostic test, therapy, etc. Clinical documentation is captured in the provider's EHR.
Phase 2: Provider → Payer (Claims Submission)
Step 5: Claim Creation
The provider's billing team creates a claim with:
- Patient demographics and insurance information
- Diagnosis codes (ICD-10-CM)
- Procedure codes (CPT/HCPCS)
- Place of service, dates of service
- Rendering provider NPI
- Billed charges
Step 6: Claim Submission
- EDI 837P — Professional claims (physician, outpatient)
- EDI 837I — Institutional claims (hospital inpatient, outpatient facility)
- EDI 837D — Dental claims
- Claims typically route through a clearinghouse (e.g., Change Healthcare, Availity, Trizetto) which validates format and forwards to the correct payer
Step 7: Claims Adjudication
The payer processes the claim through its adjudication engine:
- Intake — Claim received and logged
- Validation — Format, required fields, duplicate check, timely filing
- Eligibility — Was the member covered on the date of service?
- Benefit determination — Is the service covered under the plan? Any exclusions?
- Medical policy / clinical edits — Does the service meet medical necessity criteria?
- Pricing — Apply contracted rates (fee schedule), allowed amounts
- Coordination of Benefits (COB) — Is another payer responsible first?
- Decision — Pay, deny, or pend the claim
Phase 3: Payer → Provider + Member (Payment & EOB)
Step 8: Payment to Provider
- EDI 835 — The payer sends an Electronic Remittance Advice (ERA) to the provider detailing:
- Allowed amount
- Amount paid by plan
- Adjustment reason codes (CARCs/RARCs)
- Patient responsibility (copay, coinsurance, deductible)
- EFT (Electronic Funds Transfer) — The payment is deposited into the provider's bank account
Step 9: Explanation of Benefits to Member
The payer sends the member an Explanation of Benefits (EOB) — a document (paper or digital) showing:
- Services received and dates
- Amount billed by the provider
- Amount the plan paid
- Amount the member owes (copay, coinsurance, deductible)
- Note: The EOB is not a bill — it's an informational statement
Step 10: Patient Billing
The provider sends the member a patient statement for any remaining balance:
- Copay amount
- Coinsurance (after deductible)
- Non-covered services
- The member pays the provider directly
Step 11: Appeals (if applicable)
If a claim is denied, the provider or member may file an appeal:
- Internal appeal to the payer (typically two levels)
- External review by an independent review organization (IRO)
- Timelines and processes are regulated by state and federal law
Summary: Transaction Flow
Member → Provider: Eligibility check (270/271), Prior auth (278)
Provider → Payer: Claim submission (837P/837I/837D)
Payer → Provider: Payment + Remittance (835/ERA + EFT)
Payer → Member: Explanation of Benefits (EOB)
Provider → Member: Patient balance bill
