Documentation Mistakes Every Medical Assistant Should Avoid
August 13, 2026 • Clinical Practice
As a medical assistant, accurate documentation is a critical element of your job and one of your most important responsibilities, as it can directly affect patient care. It also serves as a vehicle for communication between providers, as well as an official legal document. Small errors in documentation can lead to delayed or unnecessary treatment for a patient, medical mistakes, insurance claim issues, patient harm, and in some cases, legal repercussions. Understanding some common mistakes that can be made during the documentation process can help you avoid them and, when necessary, correct them in a timely manner.
Here are some of the more common mistakes to look out for:
1. Failing to verify patient identity.
This is a serious mistake that can lead to incorrect patient diagnosis, incorrect and even harmful medications being administered, incorrect procedures, and billing issues. All of these things will greatly compromise the quality of the patient’s care. Never assume you know who the patient is without verifying their identity with two patient identifiers, such as full name and date of birth, BEFORE you begin the documentation process. Failing to properly identify a patient may also lead you to open up the wrong EHR (electronic health record), causing problems not only for the patient you are documenting about but also for the patient whose health record you mistakenly opened up and tampered with. Always confirm the patient's identity and make sure you have opened the correct EHR!
2. Failing to document in a timely manner.
Documentation must occur promptly, or as soon as possible, following an encounter with the patient. In cases where there is a delay, that should also be documented as to what the reason for the delay was. Waiting until the end of the day can pose the risk of not remembering the facts accurately. There is also a temptation to “guess” about the details when you wait too long, which can lead to inaccurate information. This action leads to both ethical and legal problems. Remember to document when it is fresh in your mind, and if you must delay, clearly record the time of the event and the time documentation occurred. And be sure to close and lock all EHR’s when finished.
3. Failure to obtain consent. 2
As a medical assistant, you play an important role in obtaining medical consent. In most cases, the provider is responsible for informing the patient before a treatment or procedure, but you will often witness and verify the signatures. Some problems that can arise that you should be aware of are: Not obtaining consent BEFORE the procedure, not verifying the patient’s identity, signing as a witness when you didn’t actually observe the signature, failing to document refusal of care or concerns the patient may have, and documenting consent when it was never obtained. Be honest with what you observe and don’t falsify records even if you feel pressured to do so.
4. Providing illegible documentation.
Your documentation must be clear, concise, and easy to read and understand. This information will be seen by a host of other medical professionals, and you will want to make it as easy as possible for others to understand the patient’s condition and plan of care. If you are documenting or writing notes on paper charts, make sure your handwriting is legible and not sloppy. Take the time to write in a manner that is easy to read. Pertinent details will quickly become unclear, compromising patient care and wasting time that can result in delayed care for the patient and frustration for the provider.
5. Omitting important information. 4, 5
Failure to obtain a thorough and complete medical history of the patient is of utmost importance. This takes time and patience. In order for a provider to be able to make informed decisions about a patient’s treatment, they must be able to review a complete medical history. Pertinent information should include the patient’s chief complaint in detail as to why they are seeking care. It should also detail the history of their present illness in addition to their past illnesses, surgeries, or any chronic conditions they may have. If possible, a family history of conditions should be recorded, although this may not always be possible. And finally, their social history, which can provide clues as to other risk factors they may be dealing with. Social history includes their lifestyle pertaining to alcohol and drug use, living conditions, and other health habits.
6. Altering or falsifying documentation.
Sometimes a correction or change needs to be made to a record when a mistake has occurred. It is important to follow the proper procedures when this is necessary. Common errors include: Reporting information prior to an encounter or procedure, changing documentation after signatures were obtained, and deleting documentation in order to hide errors. If a correction must be made, you should use the strikethrough method and initial and date the change in an addendum. Do NOT attempt to erase or hide the mistake, instead, notify your supervisor and ask them how you should proceed.
7. Providing subjective documentation instead of objective documentation. 3
A common mistake that many people make is allowing their own personal opinions, judgments, or assumptions to inform their documentation. Subjective documentation leaves a lot of room for interpretation and can increase legal risk, whereas objective documentation records observable facts and statements that are made by the patient. An example would be instead of saying “The patient is lazy,” you should say, “The patient states: ‘they do not like to exercise.’” Always document what you observe or what the patient states, not what you think and feel happened.
8. Use of improper medical abbreviations. 1, 5
Using medical abbreviations when documenting is an efficient and effective tool that is widely used among providers. However, it is important to know that some abbreviations can easily be misinterpreted. The Joint Commission has a “do not use” list of medical abbreviations that you should avoid.

9. Copying and pasting information. 4
Avoid copying and pasting information at all costs. By doing this, you run the risk of recording information that is incorrect or outdated, especially if you fail to verify the accuracy of the information. This can lead to a whole host of problems down the road. Documentation fatigue is a real thing. Some are tempted to copy and paste because they are exhausted, for others, it can simply be laziness. It is important that you stay vigilant when documenting in order to ensure accuracy and to avoid ethical and legal ramifications that can arise, ultimately compromising the health and safety of multiple individuals.
10. Violation of patient confidentiality.
As a provider, you are ethically and legally obligated to protect the identity of every patient. In order to do this you should refrain from talking in public spaces about a patient’s private medical information. Do not leave the computer screen open and visible when it comes to a patient’s EHR record. Do not share any passwords, discuss a patient’s information with anyone who is unauthorized to receive it (including inquisitive family members), or access or give out any patient information if you are not directly related to their case or discussing it with another provider who is directly related to their case.
As a standard rule, be aware of your audience and surroundings when handling a patient’s personal information.
Remember that no one is perfect! It is important to try to avoid these common mistakes, but if you do find yourself in a precarious position, recognize the mistake, be honest, implement corrective measures promptly, and finally, learn from this experience as you move forward!
