Hi @aferguson024
welcome to the Community!
Unfortunately, once the ‘Prevent price change’ tick-box is on for a treatment code, the fee is locked for everybody in the chart including Level 4 Administrators. If you need to change the amount you’ll have to go back to Settings → Treatments & Plans, untick the box (or amend the default fee) and save.
If you often need an admin-only price, you can leave the lock on and create a second code (e.g. “Crown – admin adj.”) with its own default fee. I’m keen to hear if other practices have found similar workarounds, feel free to comment below!
I’ll flag this with our Product team so it can be reviewed as a potential improvement. Ideas from the Community are really valuable to us, so thank you for raising it!
