Within how many days must physicians certify the need for therapy after it has started?

Physicians are required to certify the need for therapy within 30 days after the therapy has commenced. This requirement is part of adherence to healthcare regulations, ensuring that ongoing care is appropriate and justified based on the patient's condition. The 30-day window allows for an adequate assessment of the patient's response to the initial therapy while also ensuring timely documentation and compliance with payer requirements. This certification is critical for continued reimbursement and validation of services rendered, thus maintaining compliance with healthcare regulations. The specific timeframe also aligns with best practices in patient care, making it an essential element of maintaining quality standards in healthcare provision.
