Final answer:
The Centers for Medicare and Medicaid Services use HCPCS Level II coding for items and services not covered by regular health insurance, whereas other coding systems such as CPT, ICD-10, and DSM-5 serve different purposes in medical billing and diagnosis.
Step-by-step explanation:
The coding system used by the Centers for Medicare and Medicaid Services for services and equipment that are not typically covered by regular health insurance is HCPCS Level II (Healthcare Common Procedure Coding System). HCPCS Level II codes are used to identify products, supplies, and services not included in the CPT codes such as durable medical equipment, prosthetics, orthotics, and supplies when used outside a physician's office. By contrast, CPT (Current Procedural Terminology) codes are used for billing various medical services and procedures, ICD-10 (International Classification of Diseases, 10th Edition) is utilized for diagnosis coding, and DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition) is principally used in mental health for diagnosing psychiatric disorders.
Understanding these various coding systems is crucial for medical billing and ensuring that healthcare providers receive appropriate reimbursement from insurance companies, including Medicare and Medicaid.
