Billing for urgent care services involves managing the reimbursement process for medical treatments provided in urgent care centers, which typically handle non-life-threatening but immediate health issues such as minor injuries, infections, fractures, and flu symptoms. Unlike primary care or emergency room billing, urgent care billing requires specialized knowledge of place of service (POS) codes, proper use of CPT and ICD-10 codes, and understanding payer-specific rules to distinguish between urgent care and emergency services.
