G-codes are special HCPCS Level II billing codes used primarily for Medicare and Medicaid claims to document medical services and procedures not covered by traditional CPT codes. These codes ensure providers are reimbursed for unique or specialized healthcare services and streamline the billing process for outpatient, preventive, and telehealth care. Accurate use of G-codes is essential for proper reimbursement and regulatory compliance, and their specificity allows precise tracking of diverse treatments and interventions in the healthcare system. https://www.newtechrcm.com/blogs/understanding-g-codes-in-medical-billing/
