Medical Bill Review Kit

Overview

Organizes scattered medical bills and Explanation of Benefits (EOB) documents into a reviewable inventory, provides a checklist for spotting common billing errors, and prepares structured communication scripts for calls with providers and insurers.

This skill belongs to the Personal Finance Education category and has priority P0.

It is an organizational and informational tool only. It does not interpret medical codes, determine what insurance should cover, evaluate medical necessity, or provide legal advice. All coverage determinations remain with the user's insurance plan documents and the user's own conversations with their insurer and provider.

Required Inputs

To deliver a useful review kit, collect the following from the user:

• Bill inventory: For each bill — provider name, date of service, billed amount, patient name (if multiple family members), and any bill reference number.
• Insurance information: Insurance company name, plan type (if known), and whether the user has received corresponding EOBs.
• EOB details (if available): For each EOB — billed amount, allowed/negotiated amount, insurance paid, patient responsibility (copay, coinsurance, deductible), and reason codes for any denials.
• Context: Whether this is an initial bill, a follow-up, or a surprise bill (e.g., out-of-network provider at an in-network facility).

The user may provide partial data; the skill will note gaps and prompt for missing documents rather than fabricate information.

Workflow

Step 1: Build the Bill Inventory Table

Create a master table with these columns:

Sort by date of service (most recent first). Flag any entries that are duplicates, for the same service from the same provider with overlapping dates.

Step 2: Match Bills to EOBs

For each bill, help the user locate and match the corresponding EOB. Create a reconciliation table:

Flag discrepancies where:

• The bill amount exceeds the patient responsibility stated on the EOB.
• The EOB shows the service as fully covered but the provider billed the patient.
• No EOB is available for a billed service.

Remind the user: the EOB is not a bill — it explains what insurance processed. The provider's bill is the actual amount owed.

Step 3: Run the Billing Error Checklist

Guide the user through each check. This is a self-review checklist — the skill does not make determinations.

Duplicate Charges

• Does the same service code or description appear more than once for the same date?
• Are there separate bills and EOBs that appear to be for the same visit?

Upcoding / Incorrect Service Level

• Does the description match the service the patient received? (e.g., "comprehensive exam" vs. a brief follow-up)
• Is the billed time/duration consistent with the actual visit?

Unbundling

• Are separately billed items normally included in a single procedure code? (e.g., individual lab tests billed separately when a panel code exists)

Incorrect Patient Information

• Are patient name, date of birth, and insurance ID correct on all documents?
• Is each bill for the correct family member?

Balance Billing (Surprise Bills)

• Was the provider out-of-network at an in-network facility?
• Did the user receive a bill for the difference between the billed amount and the insurance payment?

Timely Filing

• Check the date of service against the insurer's timely filing deadline — was the claim submitted on time? (User should verify their plan's deadline)

Incorrect Quantity or Duration

• Are quantities (e.g., units of medication, number of therapy sessions) accurate?
• Does the billed operating room time match the actual procedure duration?

Non-Covered Services Billed as Covered

• Does the EOB show a denial for a service the user believed was covered?
• Was prior authorization required but not obtained?

Step 4: Prioritize Findings

Sort flagged items by estimated financial impact:

1. High priority: Duplicate charges, services not received, balance billing exceeding expected amounts.
2. Medium priority: Upcoding suspicions, unbundling, incorrect quantities.
3. Low priority: Minor coding errors that don't affect patient responsibility, typos without financial impact.

Step 5: Document-First Communication Prep

Before the user makes any call, recommend they assemble:

• The bill(s) in question with reference numbers.
• The matching EOB(s).
• Insurance card and plan documents.
• A note-taking template (date, who they spoke with, reference/case number, summary of discussion, next steps).
• A written list of specific questions.

Step 6: Provide Communication Scripts

Offer adaptable scripts the user can use. These are templates — the user fills in their own details.

Provider Billing Office — Bill Discrepancy Script:

"Hello, I'm calling about bill [reference number] for services on [date]. I've reviewed my Explanation of Benefits from [insurance company], and there is a discrepancy between what the EOB says I owe and what this bill shows. Can you help me understand the difference? I can provide the EOB details."

Provider Billing Office — Duplicate Charge Script:

"I'm reviewing bill [reference number] and it appears I was charged twice for [service description] on [date]. I only received this service once. Can you review the charges and correct this?"

Insurance Company — EOB Clarification Script:

"I received an Explanation of Benefits for [date of service] with [provider name]. I see the claim was [partially denied / denied] with reason code [code]. I'd like to understand why and what my options are. Can you walk me through the denial reason and whether this can be appealed?"

Insurance Company — Surprise Bill Script:

"I received a bill from [provider name] for services on [date] at [facility name], which I understood to be in-network. The provider appears to be out-of-network. Can you help me understand what protections apply under my plan and whether this falls under any surprise billing rules?"

Step 7: Follow-Up Tracking Template

Provide a simple tracking table for the user to maintain:

Output Template

Deliver the complete review kit with these sections:

1. Bill Inventory Table

Organized list of all bills provided, sorted by date with duplicate flags.

2. Bill-to-EOB Reconciliation

Side-by-side comparison of each bill with its EOB, highlighting any discrepancies.

3. Billing Error Checklist Results

Each checklist category with the user's findings documented. Where information is missing, note what's needed.

4. Prioritized Action List

Flagged items sorted by financial impact (high/medium/low) with recommended next step for each.

5. Communication Scripts

Adapted scripts for the user's specific providers and situation.

6. Follow-Up Tracker

Empty or pre-populated tracking table for the user's ongoing calls.

7. Document Checklist

List of documents to gather before making calls: bills, EOBs, insurance card, plan documents, notes template.

8. Safety Notes

Explicit boundary statement (see below).

Safety Boundaries

This skill provides organizational and informational support for medical bill review only. It does not and must not:

• Interpret medical procedure codes, diagnosis codes, or clinical terminology to determine billing accuracy.
• Provide medical advice, treatment recommendations, or evaluate the medical necessity of any service.
• Determine what an insurance plan should or should not cover — coverage questions must be directed to the user's insurance plan documents and insurer.
• Provide legal advice regarding medical debt, patient rights, or billing disputes — consult a qualified professional for legal questions.
• Make promises about bill reductions, write-offs, or outcomes of any dispute.
• Advise the user to withhold payment, ignore bills, or take any action that could affect their credit or relationship with providers.
• Act as a substitute for a professional medical bill advocate, patient financial counselor, or attorney.

The user remains fully responsible for all communication with providers and insurers, for verifying information on their bills and EOBs, and for all payment decisions. Encourage the user to contact their insurance company directly with coverage questions and to consult plan documents for specific coverage details.

If the user is facing medical debt they cannot manage, suggest contacting the provider's financial assistance program, a nonprofit patient advocacy organization, or a qualified financial counselor.

Examples

Example 1: Basic Use — Reviewing a Single Hospital Bill

User says: "I just got a hospital bill for $3,200 after my insurance supposedly paid. Can you help me figure out if it's correct?"

Skill guides:

1. Collect provider name, date of service, billed amount, and whether an EOB is available.
2. Ask user to locate the EOB and share the allowed amount, insurance paid, and patient responsibility.
3. Build the bill inventory and reconciliation — check if the bill matches the EOB's patient responsibility.
4. Run through the billing error checklist for duplicates, upcoding, and balance billing.
5. If discrepancy found, provide the provider billing office script.
6. Deliver complete review kit with safety notes.

Example 2: Detailed Session — Multiple Bills After a Hospital Stay

User says: "I had surgery last month and now I'm getting bills from the hospital, the surgeon, the anesthesiologist, and a lab. I have no idea what I actually owe. Some have EOBs and some don't."

Skill guides:

1. Collect all bills — provider names, dates, amounts, and reference numbers.
2. Help user sort by provider type and date.
3. For bills with EOBs: build reconciliation table and flag discrepancies.
4. For bills without EOBs: note as pending — recommend user request EOB from insurer or ask provider to submit claim.
5. Run the full billing error checklist across all bills (especially: unbundling for separate surgeon/anesthesiologist/lab charges, surprise billing if any provider was out-of-network).
6. Prioritize findings by financial impact.
7. Provide adapted scripts for hospital billing, surgeon's office, and insurer.
8. Set up the follow-up tracker with all pending items.
9. Deliver complete review kit with safety notes.
