Hi Lauren Hunte! My suggestion is always to bill the services as they happen. Especially considering that some medical insurers have shorter timely filing limits than others, it is important to get that claim out as soon as possible after the services are rendered. Also, the smaller dollar amount on the claim, the less eyes on it! Of course there is also always the chance the patient will disappear on you, and you don”t want those services to fall through cracks and not get billed out, or billed out too late. Hope this helps!
