Cash posting and payment posting describe the same process. Both involve recording and reconciling payments received from insurance companies or patients with corresponding claims. The terminology often depends on the payment source; ‘cash posting’ typically refers to payments made by patients or self-pay individuals, while ‘payment posting’ generally refers to payments received from insurance companies. Despite the terminology difference, the underlying process and objective remain consistent – accurately recording and reconciling payments to ensure proper financial management in the RCM workflow.
