You should consider outsourcing your billing when you do not have the proper personnel to efficiently handle the required tasks to accomplish a seamless billing process from start to finish. Having the right person, effectively trained, to do the right job is key in ensuring timely and accurate reimbursement.   Often times, the internal team is only handling the electronic billing process, but not working rejections and denials or doing proper claims follow-up to ensure the difficult claims get paid.  When we assume the billing and collections for a practice, 95% of the time, we find that rejections are sitting and have not been worked, which represents cash that is not being collections.  Likewise, if denials are not worked, claims will likely have to be written off over time.  The follow-up process is time-intensive, but required to collect all the cash that belongs to the providers and the practice.   Billing companies stay updated with changes in regulations and compliance requirements, reducing the risk of errors and potential penalties for non-compliance.  Professional billing services often result in faster processing of claims and payments, leading to improved cash flow for the practice.
