Final answer:
Surgical procedures like the one performed by Dr. Morris are generally reported using a bundled code that encompasses the approach, definitive procedure, and straightforward closure repair. Modifiers are used as necessary depending on the specific circumstances and coding guidelines.
Step-by-step explanation:
When Dr. Morris performs surgery to excise a lesion found at Mike's skull base, including both the approach and the definitive procedure along with a straightforward repair of the skull, these are generally reported using a bundled code. Each component of the surgery (approach, definitive procedure, closure, and repair) typically falls under a single comprehensive code, which reflects the complexity and inclusiveness of cranial surgery. If different aspects of the procedure, such as the approach and the closure, were distinctly separate and not usually included together, separate codes might be necessary, often with the use of modifiers to indicate the separate stages of the surgery. However, in most cases, straightforward repairs during the closure of the skull are considered part of the global surgical package and would not be reported with a separate code. The use of modifiers would depend on the specific circumstances and should follow the coding guidelines set forth by the American Medical Association's Current Procedural Terminology (CPT) codes and payer policies.
