May I get some opinions of pricing when the modifier 62 is used?

It's been my experience that you can either adjust your fee by 62.5% of bill your fee and the carrier will pay accordingly or make no adjustment and let the carrier again, determine payment.

In my current job, the fee is adjusted to 125% of the usual fee, and again, the insurance does their thing.

How many of you adjust the fee to 62.5%?

How many adjust the fee upward to 125%?

How many only append the modifier and see where things shake out?

Additionally, would you mind stating what speciality you work in? My manager would like to compare with similar practices. This is a spine surgery office.
