Types of Insurance Claims and the Process

Insurance claims come in more forms than most people realize—auto, home, health, life, business—and each one follows its own rulebook. Get the type wrong or miss a step, and payment stalls.

For healthcare providers, this complexity multiplies. Health insurance claims involve medical coding, payer-specific rules, and multi-stage review processes that can trip up even experienced billing teams. A single wrong code can delay payment for weeks.

This guide breaks down the major types of insurance claims, walks through the general and healthcare-specific claims process, and flags the pitfalls that most often cause denials or delays.

Key Takeaways

• An insurance claim is a formal request to the insurer for payment after a covered loss
• Claims fall into two types: first-party (your own insurer) and third-party (someone else's insurer)
• Health insurance claims move through coding, submission, adjudication, and payment: each step is a potential failure point
• Coding errors are the #1 cause of claim denials, according to Persistex's client data
• Practices using pre-submission audits see coding-related denials drop by an average of 35%

What Is an Insurance Claim?

An insurance claim is a formal request, filed by a policyholder or (in healthcare) by a provider on the patient's behalf, asking an insurer to pay for a covered loss. Premiums buy a promise of protection; a claim is how that promise gets paid.

It's easy to confuse a claim with related terms:

• Bill/invoice: What a provider charges for services, not the claim filed to get those services paid
• Deductible: The amount paid out of pocket before insurance coverage applies
• Lawsuit: A legal action typically reserved for disputes the claims process cannot resolve

In healthcare specifically, providers submit claims electronically on the patient's behalf far more often than patients file their own. That single distinction shapes everything about how medical claims move through the system.

Types of Insurance Claims

Claims fall into two broad categories based on who you're filing against:

• First-party claims — filed against your own insurer (health, homeowners, your own auto collision coverage)
• Third-party claims — filed against someone else's insurer (auto liability after an accident they caused)

Major Categories of Insurance Claims

There's no single federal standard defining "the" number of insurance claim types. State Farm, for example, groups coverage into four umbrellas: vehicle, home and property, personal, and small business. Each umbrella covers sub-types such as homeowners, renters, life, disability, and commercial auto.

In practice, most claims fall into five working categories:

1. Health insurance claims — provider-submitted bills for medical services, usually sent electronically with CPT/ICD-10 codes for payer reimbursement
2. Auto insurance claims — collision, comprehensive, liability, and uninsured motorist scenarios
3. Homeowners/renters claims — property damage, theft, liability, and additional living expenses
4. Life insurance claims — beneficiary-filed, requiring a death certificate and claim form
5. General/business claims — workers' compensation, business interruption, professional liability, data breaches

On timing, Texas requires insurers to pay death benefits within two months of receiving proof of death and verifying the claim. That rule is state-specific, not a national mandate, but it mirrors a broader pattern: life claims often move faster than health claims once documentation is complete.

Health Insurance Claims and the Provider's Role

Health claims start long before anything reaches a payer. Accurate medical coding—CPT, ICD-10, and HCPCS—has to happen first. Get a code wrong, and the cleanest claim in the world gets bounced.

Providers typically bill electronically using the 837P format (the CMS-1500 form's electronic equivalent), submitting to Medicare, Medicaid, and private payers alike. Patient self-submission still happens, but it's the exception rather than the rule in most practices today.

Why Health Claims Get Denied

The most common culprits:

• Coding errors — mismatched diagnosis and procedure codes, wrong modifiers
• Missing prior authorization — especially common in behavioral health and specialty care
• Eligibility issues — coverage lapsed or wasn't verified before the visit
• Incomplete documentation — missing notes to support medical necessity

Behavioral health billing carries extra complexity. Psychotherapy add-on codes, time-based CPT codes, and modifier accuracy all need careful handling—one wrong modifier on a session claim can trigger an automatic denial.

That complexity is why specialty review before submission matters. Persistex coders hold CPC, CPB, RHIT, and CCS credentials and check every claim against current MassHealth and regional payer policies before it goes out.

Pre-submission audits that validate diagnosis-to-procedure linkage have cut coding-related denials by an average of 35% for clients, with an overall clean claim rate of 98%.

The Insurance Claims Process: Step-by-Step

Every claim, regardless of type, moves through a similar sequence.

1. Review the policy and gather facts — Check coverage limits, exclusions, and filing deadlines before you do anything else.
2. Notify the insurer and file promptly — Use the correct form: CMS-1500 (or 837P electronically) for health claims, ACORD forms for property and auto.
3. Submit supporting documentation — Medical records, itemized bills, police reports, or proof of loss, depending on claim type.
4. Undergo claim adjudication — An adjuster or payer reviews the claim, verifies coverage, and calculates the payout.
5. Receive settlement, partial payment, or denial — If denied or underpaid, an appeal process is available.

The Insurance Information Institute condenses this into four broader stages: filing/notification, documentation/review, adjudication/decision, and payment or appeal. Same process, fewer buckets.

For healthcare specifically, Persistex's workflow mirrors this in three phases:

• Pre-visit: eligibility verification and prior authorization checks
• Post-visit: coding, charge capture, and claim submission
• Revenue recovery: payment posting, denial management, and A/R follow-up at 30, 60, and 90 days

That third phase matters as much as the first two. A claim that's submitted correctly can still sit unpaid without persistent follow-up. That's why appeals management is its own discipline, not an afterthought.

Avoiding Claim Denials and Delays

Timely notice and accurate documentation prevent most delays before they start. Denials still happen industry-wide, and the data shows why practices cannot ignore them. A 2023 KFF analysis of ACA Marketplace plans found 20% of in-network claims were denied, with administrative issues and lack of prior authorization among the top causes. Separately, MGMA's 2023 practice data put the single-specialty first-submission denial rate at 8%. In the same period, 60% of medical group leaders reported denial rates rising year over year. Two strategies recover revenue that would otherwise be written off:

• Chase claims on a fixed 30/60/90-day cadence instead of waiting for payer action
• Identify denial patterns and run root-cause appeals systematically, not case by case Persistex applies this same model: every denial gets investigated, not written off. That persistence produces a 72% appeals success rate. One multi-provider behavioral health clinic saw denials drop 40% and monthly revenue climb $85,000 after adopting systematic denial management.

Frequently Asked Questions

How many types of claims are there in insurance?

There's no single official count. Claims generally group into five major categories: health, auto, property, life, and liability/general—each with multiple sub-types depending on the insurer.

What are the 7 main types of insurance?

Commonly cited categories are health, life, auto, homeowners/renters, disability, liability, and business insurance. Claims correspond directly to whichever policy type is in force.

What are the four stages of insurance claims?

The four stages are filing/notification, documentation/review, adjudication/decision, and payment or appeal. This condenses the more detailed five-step process insurers typically follow internally.

What is the difference between a first-party and third-party insurance claim?

A first-party claim is filed against your own insurer under your own policy. A third-party claim is filed against another person's insurer when their coverage is responsible for your loss.

How long does it typically take for an insurance claim to be paid?

Timelines vary widely by claim type and complexity. Life insurance claims often pay within two months of verified proof of death; health claims often resolve in a few days to several weeks, depending on documentation and payer review.

Why do health insurance claims get denied?

The most common causes are coding errors, missing prior authorization, and eligibility issues. Specialized billing and coding review before submission significantly reduces these denials.
