Medical history 5 min read

What if a preexisting injury got worse after the accident?

You had pain or treatment before the crash, and now it is different. The useful record shows what was true before, what changed and when.

A prior injury does not answer what changed after a crash. Build two timelines using medical records: the condition, symptoms and treatment before the event, then the symptoms, limits, tests and care after it. Tell medical providers the history accurately. A doctor addresses medical cause, and a licensed attorney can review how state law treats the documented change.

Do not hide the earlier history

List the condition, affected body area, symptoms, treatment, medicine, tests, work limits and daily limits that existed before the crash. Use provider names and dates. If you do not remember a date, mark it approximate.

Many patients can request medical and billing records rather than rebuilding clinical history from memory.1

Build a separate after-crash timeline

Record:

  • the first new or changed symptom;
  • when you first told another person or provider;
  • each medical visit, test, referral and treatment;
  • new work or activity limits;
  • what returned to the earlier baseline and what did not.

Keep the provider’s words as written. A doctor addresses medical cause. Do not rewrite a diagnosis to make a legal point.

Put the timelines beside the crash record

Save the crash report, vehicle and scene evidence, insurer messages and exact event date. State traffic systems provide the event-side record.3 The medical record and crash record answer different factual questions.

Make missing records visible

List the provider, approximate year and record type that is missing. Federal access guidance describes which records may be in a designated record set.2 A missing copy is a task, not permission to guess.

What this page can and cannot tell you

This page cannot decide fault, medical cause, insurance coverage, legal deadlines, case value or whether you have a claim. Those questions depend on the full facts, records, state law and a licensed attorney's review.

The fine print, in normal size

This article is general information, not legal advice, and reading it does not create an attorney client relationship. Starting a case check does not mean we represent you.

Depending on the location and type of matter, another law firm may need to assist or handle it. We will identify that firm and ask permission before sharing information.
