Therapeutic plasma exchange, initial and repeat. This code is used for the first five procedures for a patient in a given year. For services exceeding this limit, see G278. This service is listed as a major invasive procedure eligible for after-hours procedure premiums (E409, E410, E412, E413) when rendered under non-elective circumstances as defined in the Schedule of Benefits on page .

When to Use

Use G277 for the first five therapeutic plasma exchange procedures performed on a patient within a single calendar year.
Apply G277 when performing non-elective plasma exchange in an urgent clinical setting to qualify for after-hours premiums like E409 or E410.
Use G277 specifically for the initial and subsequent exchange sessions until the five-procedure threshold is met, after which G278 must be used.

Common Pitfalls

Billing G277 beyond the fifth procedure in a year will result in automatic rejection; ensure you switch to G278 for the sixth procedure onwards.
Claiming after-hours premiums (E409, E410, E412, E413) for elective plasma exchange procedures is a common audit trigger, as these codes strictly require non-elective status.
Failure to distinguish between the physician types (Emergency vs. non-Emergency) leads to incorrect premium code selection, such as using E409 instead of E412.

Billing Tips

Track the patient's annual procedure count meticulously to ensure you transition from G277 to G278 on the sixth session to avoid claim rejections.
If you are an Emergency Department physician, always use the 'H' prefix and select E412 or E413 to ensure the correct premium percentage is applied to the G277 base fee.
