Hi talk2us@finetunegums.com!

Great questions, the injection codes actually pertain to number of muscles instead of number of sessions or injections:

20552 = Injection(s); single or multiple trigger point(s), 1 or 2 muscle(s)
20553 = Injection(s); single or multiple trigger point(s), 3 or more muscle(s)

Modifier -50 = Bilateral Procedure
Modifier -RT = Right Side
Modifier -LT = Left Side

I don't believe the use of these modifiers is generally required when billing medical insurers, but may not necessarily cause a denial if used either.

Here is a link to an sample medical policy for trigger point injections from Anthem BCBS:

If there is a particular insurer you're interested in seeing the medical policy for, I am happy to help if you have the name of the insurer handy :)

J0585 = Injection, onabotulinumtoxina, 1 unit

So this J code is actually related to botox injection

Hope this helps, please feel free to contact us with any further questions!
