Your Health Plan Wants Repaid: Subrogation in New Mexico

Sources checked: August 31, 2026. This page provides general information, not legal, medical, or insurance advice.

Identify the sender and the exact request

A letter may come from a health insurer, employer plan, third-party administrator, recovery vendor, attorney, or another entity. Record the full sender name, address, reference number, date, plan name, and the exact words used. Keep the complete letter, attachments, return envelope, portal message, and any deadline stated in the document.

Do not assume that every accident questionnaire, benefits statement, reimbursement request, or explanation of benefits is the same kind of document. A factual record of who sent what and when is a better starting point than a conclusion about whether a request controls every insurance or injury question.

Ask for the plan materials that describe the request

The U.S. Department of Labor explains that participants in many ERISA-covered health benefit plans receive a Summary Plan Description, or SPD, describing how a plan operates and the rights and responsibilities of participants. The Department also explains that plan documents and certain other materials may be available upon request. If a request cites plan terms you do not have, ask in writing for the specific document, section, and version relied upon.

Keep the Summary Plan Description, Summary of Benefits and Coverage, plan document if available, notices of material changes, explanation of benefits, and correspondence together. Do not replace a complete plan document with a one-page billing summary or a screenshot from a portal. Different documents can describe different parts of coverage or administration.

Separate health-plan records from auto and injury records

Health-plan materials may include explanations of benefits, itemized statements, payment history, plan notices, and correspondence. Auto-insurance materials may include a declarations page, policy, claim number, repair documents, and letters. Event records may include original photographs, location, report number if available, and a factual timeline. Each group can answer a different question.

A health-plan statement does not describe every term of an auto policy, and an auto-insurance letter does not necessarily state what a health plan paid or why. Keeping the sources distinct reduces the chance that an estimate or benefit statement is treated as a complete answer when it is not.

Read the amount and dates with the underlying documents

If a letter identifies an amount, compare it with the explanation of benefits, provider invoices, payment history, and dates listed in the request. Preserve the originals and note any difference without changing the documents. Ask the sender to identify the transaction, service date, plan provision, or record behind an amount that is unclear.

This comparison is a recordkeeping step, not a decision about repayment. Different plan types, documents, and facts can change what needs review. Do not agree with a figure, authorize a payment, or characterize an obligation simply because an amount appears in a letter before you understand the underlying documents.

Plan type can affect which documents are useful

HealthCare.gov explains that a Summary of Benefits and Coverage is a plain-language summary of plan benefits and coverage, and people can request a copy from the insurer or group health plan. The Department of Labor explains that many private-sector workplace plans have their own plan materials and claims procedures. Government-sponsored and certain other plans can have different structures. Ask the plan administrator or insurer which documents describe your plan.

Do not rely on another person’s plan, a generic social-media post, or the name of an employer to decide what your own plan says. The relevant version, dates, and plan identification should be preserved with the request you received.

Keep communications factual and in writing

When responding to a request, keep a copy of what you send and the confirmation of delivery. If the sender asks a question you do not understand, ask for clarification of the particular request, document, or plan section. A short call note can include date, person or department, reference number, question asked, and next step.

Avoid filling gaps with speculation about medical care, policy coverage, blame, or a final payment. A factual correspondence file helps retain the distinction between what a document says and what still needs individual review.

A private review can start with the plan documents

A private review can help organize a health-plan request, plan documents, explanation of benefits, other insurance correspondence, and the event records that require individual attention. It should not promise whether repayment is required or assign a value from a general web page.
