True or False: It is acceptable to assign a code that approximates the service if the exact code is not located.

In the context of assigning codes in CPT and HCPCS Level I, it is important to select the most accurate and specific code that reflects the procedure or service performed. If an exact code cannot be located for a specific service, it is not appropriate to assign a code that merely approximates the service. Coding practices emphasize the importance of specificity and accuracy to ensure proper billing and healthcare documentation. Assigning an approximate code could lead to billing discrepancies, incorrect reimbursements, or complications in patient records.

The correct approach when faced with the absence of an exact code is to look for the closest match or utilize an unlisted code if applicable. Unlisted codes can be used when a service is performed that does not have a specific CPT code, but they still require additional documentation and justification for use. This approach aligns with coding guidelines which prioritize accuracy and specificity rather than approximation.
