Work Comp and No-Fault Auto treat the expiration date of a prescription differently. You need to understand the difference to make sure you get paid for all your sessions.

Work Comp

Is very strict on the expiration date. You must not treat before or after the valid date range of the prescription.

No Fault Auto

First, know that the start date is the date the prescription was signed (unless indicated otherwise.)

If treatment begins some number of days past the start date, it can continue that same number of days (with a maximum of 7) past the end date.

Except for extenuating circumstances, the responsibility to ask for any extension falls to the patient. Normally this energy is better spent on trying to get a new prescription rather than trying to get an extension.

If you want some more background, keep reading, but it is not required:

The insurance companies know it takes some time to begin treatment after the prescription, and that is why there is some flexiblity. However, in practice it usually takes longer than 7 days from seeing the doctor to end up on the massage table.

The insurance companies only want to pay for treatment that is needed. They know that sometimes injuries resolve on their own, and that is why they want the doctors evaluation to be as current as possible.

Some good companies like State Farm are more flexible with end dates. Some of the least expensive companies like GEICO are not flexible.
