It vary from carrier to carrier. Some payers require procedure code only once with "2" in the units of service box on the claim form and some require RT< with two separate lines. So I would suggest to work with your payers to determine correct method of billing. If you are billing for medicare, then use two separate lines with RT< as Medicare prefer 2 separate lines with RT and LT only.

If you are performing Bilateral x-ray of Knee, you have to consider two categories of codes.
1st: 73560-73564: For these category of codes you can use "RT" or "LT" modifiers.
2nd: 73565: It is itself a bilateral code. So, modifier like "RT" or "LT" or mod.50 can't be used.

Now, the tricky situation comes if there is a situation that tells you to code from both the categories of codes. The guidelines have changed over the years. If such a problem crops up, plz post your question with details. I would like to answer that with more elaboration.
