Sample COT - Certified Ophthalmic Technician Practice Questions
Try these questions from our free COT - Certified Ophthalmic Technician practice tests. The correct answer and an explanation follow each question.
A certified ophthalmic technician discovers that a colleague has been falsifying patient visual acuity measurements to expedite appointments. What is the technician's primary ethical obligation?
- A. Report the falsification to the supervising ophthalmologist or appropriate authority
- B. Confront the colleague privately and ask them to stop
- C. Document the incidents in a personal log but take no immediate action
- D. Ignore the situation since it does not directly affect patient care
Answer: A. Report the falsification to the supervising ophthalmologist or appropriate authority
COT ethical standards require reporting conduct that endangers patients or compromises care integrity. Falsifying clinical measurements directly impacts diagnostic accuracy and patient safety, obligating the technician to escalate the matter to supervisory or administrative authority rather than handling it informally or ignoring it.
A COT notices that a co-worker without any JCAHPO certification is representing themselves as a 'Certified Ophthalmic Technician.' According to JCAHPO's Code of Ethics, the COT should:
- A. Ignore the situation as it is not their responsibility
- B. Report the misrepresentation to JCAHPO and/or practice management
- C. Lend the co-worker their certification card temporarily
- D. Advise the co-worker to simply stop using the title informally
Answer: B. Report the misrepresentation to JCAHPO and/or practice management
JCAHPO's Code of Ethics requires certified individuals to report fraudulent use of credentials to protect the integrity of certification.
A patient scheduled for cataract surgery tells the ophthalmic technician they are unsure whether they want to proceed and have not signed the consent form. The surgeon is ready to begin. What is the most appropriate action for the technician?
- A. Proceed with pre-operative preparation since the surgeon is waiting
- B. Notify the surgeon that the patient has not consented and is uncertain
- C. Ask the patient to sign the consent form quickly before the surgeon arrives
- D. Reassure the patient and escort them to the operating room
Answer: B. Notify the surgeon that the patient has not consented and is uncertain
Informed consent must be obtained voluntarily before any procedure. The technician's duty is to halt preparation and notify the surgeon so the patient can have their questions addressed and consent obtained properly. Proceeding without consent violates patient rights and exposes the facility to legal liability.
An ophthalmic technician is asked by office management to bill Medicare for a comprehensive eye exam when only a brief problem-focused visit was performed. The technician should:
- A. Submit the billing as directed since management has final authority
- B. Upcode the claim only if the patient has a secondary insurance to cover the difference
- C. Refuse and report the request through the practice's compliance channel or to authorities
- D. Bill the comprehensive exam code but reduce the charge to make it seem reasonable
Answer: C. Refuse and report the request through the practice's compliance channel or to authorities
Submitting a claim for a more complex service than was actually provided is upcoding, which constitutes healthcare fraud under the False Claims Act. Technicians and all healthcare staff have an ethical and legal obligation to refuse participation in fraudulent billing and to report it through internal compliance mechanisms or, if necessary, to the Office of Inspector General (OIG).
