Final answer:
The overall process of planning for, implementing, and monitoring the ICD-10-CM transition required approximately ten years, involving systems upgrades, staff training, and extensive testing.
Step-by-step explanation:
The ICD-10-CM transition was an expansive and complex undertaking for the healthcare industry in the United States. The correct answer to how many years the planning, implementing, and monitoring of the ICD-10-CM transition required is ten years. This process included a variety of tasks such as systems upgrades, training of coders and healthcare providers, and extensive testing to ensure that everything worked smoothly once the new codes were in use.
It's essential to acknowledge that the transition didn't happen overnight. There were multiple stages in the process, beginning with the planning and assessment phase, moving through to the actual implementation, and finally culminating in post-implementation monitoring and optimization of the use of ICD-10-CM codes in real-world clinical and billing processes.
