Free CPMS Medical Coding and Revenue Questions and Answers — Questions and Answers
Question 1: A physician informs the scribe that the patient has a sprained ankle. For the most accurate ICD-10-CM coding, which additional detail is most critical for the scribe to document if provided by the physician?
- The patient's preferred pharmacy
- The color of the bruising on the ankle
- The specific ligaments involved and laterality (right/left) (Correct answer)
- The time of day the injury occurred
Correct answer: The specific ligaments involved and laterality (right/left)
ICD-10-CM codes require a high level of specificity to accurately represent the patient's condition. For injuries like sprains, this includes the exact anatomical location, the specific ligaments affected if known, and the laterality (right or left side). This level of detail is crucial for proper billing, establishing medical necessity, and tracking health data. The other options are not relevant for diagnostic coding.
Question 2: In the context of the healthcare revenue cycle, what is the primary purpose of the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code set?
- To report medical, surgical, and diagnostic procedures and services.
- To identify the provider's level of medical decision making.
- To describe and track durable medical equipment (DME) and supplies.
- To represent patient diagnoses and establish medical necessity for services rendered. (Correct answer)
Correct answer: To represent patient diagnoses and establish medical necessity for services rendered.
ICD-10-CM codes are used to document patient diagnoses. In the revenue cycle, they are used on insurance claims to communicate *why* services were provided. This establishes the medical necessity for the procedures and services that are billed using a different code set (CPT).
Question 3: Which of the following best describes how a scribe's detailed documentation of the History of Present Illness (HPI) and Review of Systems (ROS) directly impacts Evaluation and Management (E/M) coding under the 2021 guidelines?
- It directly determines the final diagnosis code assigned to the patient.
- It supports the level of Medical Decision Making (MDM) by capturing the complexity of problems addressed. (Correct answer)
- It is used to bill for the scribe's time separately from the physician's service.
- It automatically generates the CPT code for any procedures performed during the visit.
Correct answer: It supports the level of Medical Decision Making (MDM) by capturing the complexity of problems addressed.
Under the 2021 E/M guidelines, the code level for office visits is primarily determined by the complexity of Medical Decision Making (MDM) or total time. A scribe's thorough documentation of the HPI and ROS provides the detailed clinical information (e.g., number and complexity of problems, data reviewed) that substantiates the provider's MDM, thereby supporting the chosen E/M code level.
Question 4: A physician diagnoses a patient with diabetes and performs a foot exam to check for neuropathy. To ensure proper billing and demonstrate medical necessity, the scribe's documentation should clearly:
- Link the foot exam procedure to the diabetes diagnosis. (Correct answer)
- Note the brand of the patient's glucose meter.
- Record the patient's insurance provider information in the clinical note.
- Mention that the patient is due for an annual physical.
Correct answer: Link the foot exam procedure to the diabetes diagnosis.
This concept is known as 'linkage.' For an insurance claim to be paid, the services performed (represented by CPT codes) must be medically justified by a relevant diagnosis (represented by ICD-10-CM codes). The scribe's note must create a clear narrative connection showing the physician performed the foot exam *because of* the patient's diabetes to prove medical necessity to the payer.
Question 5: The term 'upcoding' refers to the fraudulent practice of:
- Billing for a service that was never rendered to the patient.
- Failing to document services thoroughly, leading to a lower-level code being assigned.
- Using a billing code for a more complex or expensive service than what was actually provided. (Correct answer)
- Submitting a claim to a secondary insurer before the primary insurer has paid.
Correct answer: Using a billing code for a more complex or expensive service than what was actually provided.
Upcoding is the illegal practice of assigning a billing code for a service that is more complex, and therefore reimburses at a higher rate, than the service that was truly performed. Meticulous and accurate documentation by the scribe helps create a clear record that justifies the codes selected by the provider or coder, preventing accusations of upcoding.
Question 6: Which of the following documentation elements, when captured accurately by a scribe, is essential for supporting a Current Procedural Terminology (CPT) code for a laceration repair?
- The patient's tetanus immunization status.
- The length, location, and complexity (e.g., simple, intermediate) of the repair. (Correct answer)
- The name of the nurse who assisted with the procedure.
- The manufacturer of the suture material used.
Correct answer: The length, location, and complexity (e.g., simple, intermediate) of the repair.
CPT codes for procedures like laceration repairs are highly specific. The correct code is determined by key details including the anatomical location of the wound, its length in centimeters, and the complexity of the closure (simple, intermediate, or complex). A scribe's precise documentation of these elements is critical for the coder to select the appropriate CPT code, ensuring accurate billing.
