Decoding Medical CPT® Codes: How to Review Your Itemized Hospital Bill for Potential Errors

Receiving a hospital statement for $10,000, $25,000, or more without a clear explanation can be overwhelming. A summary statement may not contain enough detail to understand how individual charges were calculated. Consumers can request access to medical and billing records and ask their healthcare provider or health plan for clarification of available billing and coding information before deciding how to address disputed or unclear charges.

Reviewing hospital billing records and medical billing information

Detailed billing records and available coding information can help consumers review charges and ask informed questions about a medical bill.

1. Summary Statements: Why They May Not Show Every Billing Detail

After receiving hospital care, patients may initially receive a statement that summarizes charges by broad service category rather than displaying every underlying billing entry. The format and level of detail can vary by hospital, health system, insurer, state requirements, and the records maintained for the individual account.

A summary statement can therefore make it difficult to determine what individual services, supplies, or other charges contributed to the total. Requesting access to relevant existing medical and billing records may provide additional information that can help a patient understand and review the bill.

Federal HIPAA Access Right — What It Actually Covers

Under the HIPAA Privacy Rule, including 45 CFR § 164.524, an individual generally has the right to inspect and obtain a copy of protected health information about the individual that is maintained by a covered entity in a designated record set, subject to applicable exceptions and limitations. Designated record sets can include medical records, billing records, payment records, claims information, and other records used to make decisions about the individual.

Important: HIPAA access rights apply to information that is maintained in the applicable designated record set. They do not necessarily require a healthcare provider to create a new document, new coding analysis, or a newly generated itemized statement containing every CPT® or Revenue Code if that information is not maintained in the relevant records. Patients may nevertheless request existing billing records and ask the provider to supply or explain available coding information.

2. Four Billing Issues Worth Checking

When more detailed billing information is available, consumers may be able to compare the statement with their explanation of benefits, medical records, services they remember receiving, and information supplied by the provider or insurer. The following are examples of issues that may warrant clarification; their presence does not by itself establish that a bill is incorrect.

Potential Coding-Level Questions

A service may appear under a billing level or classification that the patient does not understand. The code alone does not establish an error. Patients can ask the provider or insurer to explain how the billed service was selected and whether the supporting documentation is consistent with the charge.

Possible Duplicate Charges

Similar laboratory services, imaging services, medications, supplies, or other entries may appear more than once. Some repeated entries may be appropriate, while others may require clarification from the provider or insurer.

Bundling or Unbundling Questions

Certain services may be billed separately or together depending on applicable coding, payer, contractual, and reimbursement rules. If several related charges appear separately, consumers can request an explanation rather than assuming that the billing structure is improper.

Services or Supplies You Do Not Recognize

A bill may contain a service, medication, supply, or diagnostic procedure that the patient does not recognize. This may justify asking the provider to explain the charge and, where appropriate, requesting supporting records or correction of an identified error.

3. What to Do When Reviewing a Detailed Medical Bill

Request Existing Medical and Billing Records: Ask the healthcare provider where HIPAA access requests or billing-record requests should be submitted. A covered entity may require a written request and reasonable identity verification. Follow the provider’s applicable submission procedure.
Compare the Available Information: Review the bill together with your explanation of benefits, relevant medical records, information supplied by the provider or insurer, and current authoritative or properly licensed coding resources where appropriate. A code or charge appearing on a statement does not by itself establish that billing is incorrect.
Ask for Written Clarification or Correction: If you identify a charge you do not understand or believe may be inaccurate, describe the specific issue and ask the provider or insurer to explain it or correct any confirmed error.
Keep a Documentation File: Retain copies of requests, statements, explanations of benefits, responses, delivery confirmations, dates, and representative names. Do not rely solely on telephone conversations for important billing disputes.

HIPAA Access Request Timing

When 45 CFR § 164.524 applies, a covered entity generally must act on an individual’s HIPAA access request within 30 calendar days after receiving it. The regulation permits one additional extension of up to 30 days in qualifying circumstances if the covered entity provides the required written notice within the initial period.

This HIPAA response period should not be interpreted as automatically postponing a payment due date, collection activity, contractual deadline, insurance deadline, or legal deadline. Those issues may be governed by separate federal or state law, contracts, provider policies, payer requirements, or the facts of the individual matter.

4. What to Do If Requested Billing Information Is Not Provided

A request for a newly created itemized statement is not necessarily the same as a HIPAA request for access to existing protected health information. If a provider does not supply requested coding detail, first determine whether the information exists in medical or billing records maintained in a designated record set and whether the request is being made under the appropriate access procedure.

Request Access to Existing Records: If appropriate, state that you are requesting access to existing medical and billing records maintained about you under the HIPAA Privacy Rule, rather than asserting that the provider must create a new coding document.
Ask for the Correct Department: A provider may direct record-access requests to Health Information Management, Medical Records, a Privacy Office, Patient Financial Services, or another designated office. Ask where your particular request should be submitted.
Follow Reasonable Verification Procedures: Healthcare providers may take reasonable steps to verify the identity or authority of the person requesting protected health information. Follow legitimate verification procedures while retaining copies of what you submitted.
Ask for a Written Response: If a HIPAA access request is denied in whole or in part, the HIPAA Privacy Rule contains requirements governing written denial notices and, in certain circumstances, review rights.
Maintain a Written Paper Trail: Record dates, representative names, delivery confirmations, written responses, and the exact information requested. Documentation can help establish what was requested and how the provider responded.

Billing and coding determinations can be complex. Whether a medical charge is valid or accurately coded may depend on clinical documentation, payer contracts, benefit terms, reimbursement rules, coding standards, provider records, federal law, state law, and other facts. Similar or repeated charges do not necessarily establish improper billing.

Laws and policies can change. Federal and state laws, agency guidance, insurance requirements, coding standards, provider procedures, and regulatory interpretations may change. Users should independently verify current requirements and should seek qualified professional advice when a matter involves substantial money, active collections, litigation, credit consequences, an appeal deadline, or another significant legal or financial issue.

Privacy notice. Consumers should avoid sending medical records, account numbers, Social Security numbers, insurance identifiers, or other sensitive health or financial information through ordinary email or unsecured website forms unless a specific secure process expressly requires and protects that information.
