How to fix an error in your medical records

Read a complete copy of your medical record and you will find something wrong in it. Not because your clinicians are careless, but because a record is built from thousands of entries made quickly, by many people, often copied forward from an earlier visit. Most errors are harmless. Some are not: a drug allergy that is missing, a medication you stopped years ago that is still listed, a diagnosis that was a working guess and now reads as settled fact.

The previous post covered how to get the whole record. This one covers what to do when it is wrong. The short version: you can correct facts, you can annotate opinions, and neither happens automatically anywhere except the organization you ask.

Common errors, and which kind each is

It helps to sort what you found before you write to anyone, because the fix differs.

Factual errors are the easiest case. Wrong date of birth, wrong medication or dose, wrong laterality, a procedure you never had, an allergy listed for the wrong drug, a lab value transcribed incorrectly from the report, “non-smoker” when you smoke or the reverse, a family history that belongs to a sibling. These have a correct answer and you can usually document it.

Another patient’s information. A note, result, or diagnosis that is not yours, usually from a chart merge or a mis-filed document. This is both a correction and a privacy incident, and organizations tend to move on it quickly once told.

Copy-forward. A symptom, exam finding, or plan that was true once and has been pasted into every note since. “Patient reports improvement” appearing unchanged for three years. This is fixable, but the fix is an addendum to the current note, not the deletion of thirty old ones.

Clinical judgment you disagree with. A diagnosis you think is wrong, a note that describes you as anxious or non-compliant, a phrase like “patient denies” when you remember saying the opposite. The law does not let you make a clinician un-believe what they believed at the time. It does let you attach your account permanently, which is often what matters when the next reader opens the chart. The post on how a diagnosis follows you explains why that matters.

Start with the exact entry

A request that says “my record has errors” goes nowhere. For each error, write down:

• The document: note, problem list, medication list, result, or billing record.
• The date of service and the author, if a note.
• The exact text as it appears.
• What it should say.
• Evidence, if you have any: the pharmacy record showing the actual medication, the lab report showing the actual value, the operative report from the other hospital.

If you cannot point to the entry, you have not finished getting your record. Go back to the access request first.

Ask informally first

For factual errors, the fastest fix is often the clinician who wrote the entry, or the practice that maintains the medication and problem lists. A portal message or a minute at the next visit is frequently enough. Most systems let a clinician add an addendum to a signed note, update a list, and mark an entry as entered in error.

Two reasons to do this before anything formal. It is faster, and a portal message is itself part of your record, so even an ignored request leaves a dated trace that you raised the issue.

If the informal route stalls, or the error is a judgment rather than a fact, move to the formal process. It gives you deadlines and a written answer.

The formal amendment request

Under 45 CFR 164.526 you have the right to ask any covered provider or health plan to amend information in your designated record set that you believe is inaccurate or incomplete.

The mechanics:

• In writing. The organization may require it, and you want the paper trail regardless. Address it to Health Information Management or the privacy officer. Many organizations have an amendment form. Use it, and attach your own letter.
• One entry per request, or a numbered list. Each item needs its own decision. Mixing a medication error with a disputed diagnosis invites a single denial that covers both.
• Say what is wrong and what is right. A request to “remove” something is usually denied, because records are not deleted. Ask that the entry be amended to read a certain way, or that a correction be appended.
• Attach evidence. The regulation lets them deny a request if they judge the record accurate and complete. Documentation shifts that judgment.
• Name who should be told. If the amendment is accepted, the organization must make reasonable efforts to notify people you identify, and others it knows have the information and may have relied on it. List them: your other providers, your pharmacy, your insurer, any health information exchange you know they participate in.

A workable letter:

I am requesting an amendment to my medical record under 45 CFR 164.526.

Record: progress note dated [date], authored by [name], page [n]. Current text: “[quote].” Requested amendment: “[correct text].” Reason: [one or two sentences]. Supporting documentation is attached.

If this amendment is accepted, please notify [list], who have received this information. If it is denied, please provide the written denial the regulation requires, including the basis for the denial and how to file a statement of disagreement.

Deadline. They have 60 days to act. They may take one 30-day extension if they tell you in writing why, within the first 60.

If they accept

The organization must identify the affected records, append or link the amendment to them, tell you, and notify the people you named plus others who have relied on the information. Ask for confirmation of who was notified. Then get a fresh copy of the affected page to check that the change actually appears where the next clinician will see it, not only in a correspondence folder.

If they deny

A denial is allowed on four grounds: the organization did not create the information, the information is not part of your designated record set, you would not have a right to inspect it, or they judge it accurate and complete. The last is the usual one for anything involving clinical judgment.

The denial must be in writing and must tell you the basis, that you may submit a statement of disagreement, how to file it, that you may instead ask that your request and their denial be included with any future disclosure of the information, and how to complain. If the denial you receive is a phone call or a one-line note, ask for the written version. It is required.

Write the statement of disagreement. This is the most useful tool you have for anything the organization will not change. It becomes part of the record and must be sent along with, or summarized in, any later disclosure of the disputed information. The next clinician who pulls the chart sees your account next to the entry.

Make it short, factual, and dated. State what the entry says, what you say happened, and any evidence. Leave out anger. It will be read by strangers who will judge you as much as the entry, and a calm paragraph is more persuasive than a page. The organization may write a rebuttal, and it must send you a copy.

The “we did not create it” denial. If the disputed entry came from another organization, a consult letter or an outside result, your request goes to the originator. The organization holding the copy can only amend once the originator has, unless you can show the originator no longer exists. It is worth asking them to note in the chart that the entry is disputed and that you have raised it with the source.

The correction does not travel on its own

This is the part people find hardest. Every organization that pulled a copy of your record, through a health information exchange, a national network, or a referral, holds its own copy. Amending the source does not change theirs. The notification requirement helps, but it reaches only the people the organization knows about and chooses to contact.

So repeat the exercise wherever the error has spread. Your other providers, your pharmacy’s allergy and medication profile, your insurer’s claims record. For each, the same request, with the accepted amendment from the source attached as evidence. That attachment turns a judgment call into a paperwork step.

When the process itself fails

If the deadline passes with no answer, or the denial is missing what the regulation requires, escalate to the organization’s privacy officer, then to the HHS Office for Civil Rights, which takes complaints about amendment rights as well as access rights. You generally have 180 days from the violation to file.

Errors in lab results are a special case. The value in your chart usually came from the performing laboratory, and if the laboratory reported it wrong, the laboratory issues a corrected report and the chart updates from that. If your doctor’s office transcribed it wrong, the office fixes it. Ask which happened before you write to anyone.

Keep your own corrected copy

Whatever the outcome at the source, you can hold a version of your record that is right. If you keep your results in HealthViewer, the import preview lets you correct a value, unit, or date before it is saved, and the journal is a place to record what you disputed, when, and what the organization said. The next time a clinician asks about the entry, you have the date of your request and the text of your statement in front of you rather than a memory of having sent something once.

HealthViewer is a lab results tracker that stores everything in an encrypted file on your own computer. It cannot amend anyone else’s record. It can make sure you know exactly what is in yours.
