What is the impact of coding a procedure without proper documentation of medical necessity?
Without proper documentation of medical necessity, a claim may be denied by insurers, as they
may determine that the service or procedure was not justified. Accurate and thorough documentation is
essential to support the clinical need for the procedure and ensure reimbursement.
Explain the difference between an "open" and "closed" fracture and how they are coded.
An open fracture involves a break in the skin or a wound that communicates with the fracture
site, while a closed fracture does not involve the skin. The coding differs, with open fractures typically
requiring a more specific, higher-level code due to the increased complexity of treatment.
What are the coding requirements for a "routine" versus "emergency" surgery?
Routine surgeries are typically elective and scheduled in advance, whereas emergency surgeries
are performed as a result of an urgent medical condition. The coding for emergency surgeries requires
more detailed documentation, including the reason for the urgency and the immediate nature of the
procedure.
How do you handle coding for a procedure performed during the same encounter as another unrelated
procedure?
Each procedure should be coded separately using appropriate CPT codes, with modifiers used to
indicate that the procedures were performed during the same encounter but were not related to one
another. Modifier 59 may be used to indicate that the procedures were distinct and separate.
What is the role of the HIC code in medical coding, and how does it affect claims submission?
The Health Insurance Claim (HIC) code is used by the Centers for Medicare and Medicaid Services
(CMS) to identify specific insurance plans and policies. It affects claims submission by ensuring that
claims are correctly directed to the appropriate payer for reimbursement.

,How do you code for a routine physical examination for a new patient?
A routine physical examination for a new patient is coded using a preventive medicine code (e.g.,
CPT 99381-99387) depending on the age of the patient. The code should reflect the complexity of the
examination and the time spent on preventive care services.
What is the difference between a diagnostic code and a procedural code, and why is it important to
distinguish between them?
A diagnostic code (ICD-10-CM) represents a patient's condition or disease, while a procedural
code (CPT or ICD-10-PCS) represents the treatment or service provided. It is crucial to distinguish
between them to ensure accurate claims submission and appropriate reimbursement for services
rendered.
How does coding for a follow-up visit differ from coding for an initial visit?
A follow-up visit typically involves less extensive documentation than an initial visit, as the
physician is primarily reviewing the patient's progress. The coding for follow-up visits will reflect fewer
E/M elements than an initial visit, affecting the level of reimbursement.
What is the purpose of the "CPT Assistant" and how does it aid coders in the coding process?
The CPT Assistant is an official publication by the American Medical Association (AMA) that
provides guidance and clarification on the correct use of CPT codes. It helps coders by offering
authoritative interpretations and examples to ensure accurate and compliant coding practices.
How does the concept of "bundling" affect the coding of multiple procedures performed during the
same session?
Bundling refers to grouping related procedures together under a single code, which prevents
double billing for services that are typically performed together. It ensures that multiple procedures are
not separately reimbursed when they are part of a single comprehensive service.
What are the key considerations when coding for a patient's long-term medication management during
an office visit?
When coding for long-term medication management, the coder must ensure that the patient’s
medication history, ongoing treatment, and any changes or adjustments are documented. The visit’s
complexity and medical necessity will guide the selection of the appropriate E/M code.

, How does coding for a procedure performed during a global period differ from coding a procedure
performed outside of that period?
Procedures performed during a global period are generally considered part of the original
procedure, and therefore, should not be coded separately unless they meet specific criteria for
additional reimbursement. Procedures outside of the global period are coded independently with
appropriate billing.
How does the physician's involvement in a service affect the code selection for that service?
The physician's involvement determines the level of service provided and the code selection.
Services requiring the physician's direct involvement, such as performing a procedure, may warrant
higher-level codes compared to services performed by non-physician providers or staff.
What is the importance of using the correct ICD-10 code for a patient's diagnosis, and how does it
impact reimbursement?
Using the correct ICD-10 code ensures that the diagnosis is accurately represented, which affects
the reimbursement amount. Incorrect codes can lead to claim denials or underpayment as the insurer
may question the medical necessity or appropriateness of the treatment.
Explain the difference between a primary diagnosis and a secondary diagnosis and when each should be
used.
A primary diagnosis is the main condition responsible for the patient’s visit, while a secondary
diagnosis refers to additional conditions that coexist and may affect treatment. Both diagnoses must be
properly documented to reflect the full scope of care provided and ensure proper reimbursement.
What role do payer policies play in the coding and reimbursement process?
Payer policies dictate how services are coded, billed, and reimbursed based on their specific
rules. Coders must stay updated on payer guidelines to avoid incorrect coding and ensure timely
reimbursement for services rendered.
What is the purpose of coding audits, and how do they impact the work of a CPC?
Coding audits are performed to review coding accuracy and compliance with regulations. They
help identify areas of improvement, prevent fraud, and ensure the integrity of claims. Audits impact
CPCs by requiring them to maintain high standards of coding accuracy and documentation.
