Medical billing in the USA faces several common challenges, including navigating complex and frequently changing coding systems, such as ICD-10 and CPT codes. Ensuring accuracy in claim submissions is critical, as errors can lead to claim denials or delays in reimbursement. Additionally, the medical billing services must comply with numerous regulations and payer-specific requirements, which can be time-consuming and confusing. Providers also struggle with managing denied claims, coordinating with insurance companies for proper payment, and dealing with patient billing issues. The increasing prevalence of value-based care models adds further complexity, requiring billers to adapt to new payment structures and performance metrics.
