Final answer:
The Medicare Catastrophic Coverage Act of 1988 required the inclusion of ICD-9-CM diagnosis codes on all Medicare claims to enhance data accuracy and ensure appropriate reimbursement. These codes are essential for medical coders and billers in processing insurance claims, and they are used in various healthcare settings.
Step-by-step explanation:
The Medicare Catastrophic Coverage Act of 1988 mandated the reporting of ICD-9-CM diagnosis codes on D.) all Medicare claims. This means that when a claim is submitted to Medicare, it must include the appropriate ICD-9-CM codes to detail the diagnosis associated with the medical services provided. This requirement was designed to improve the accuracy and consistency of data collected on Medicare patients and to ensure appropriate reimbursement for services provided.
Two examples of locations where you are likely to find an ICD code are on medical laboratories requisitions, to identify tests that must be performed, and used by health-care management systems to verify that treatments and laboratory work align with the given diagnosis. Medical coders and medical billers also play a significant role, using these codes to process claims for insurance reimbursement efficiently.
In regards to Medicare, it is a public healthcare system that offers insurance primarily to people over sixty-five years old and is partially funded by payroll deductions. Medicare consists of different parts including Part A which deals with hospital charges, requiring beneficiaries to pay deductibles and copayments for certain services.
