What 90997 covers
Hemoperfusion is an extracorporeal blood-purification treatment in which blood passes through a cartridge containing adsorbent material that binds selected substances. It may be used in hospital care for severe poisoning or other toxic exposures when this removal method is chosen. Nephrologists and other physicians involved in acute toxicology or critical care may report the service when they provide the hemoperfusion treatment.
Report one service for each treatment, supported by documentation identifying the indication, treatment performed, and physician involvement. Do not substitute a dialysis-evaluation code merely because blood is processed extracorporeally; choose according to the actual method. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity, while co-surgeons and team surgery are not permitted.

How to choose
- 90945Dialysis evaluation
- 90945 describes dialysis other than hemodialysis with a single physician evaluation. Choose 90997 when the performed treatment is hemoperfusion using an adsorbent cartridge.
- 90947Dialysis evaluation
- 90947 is for other dialysis with repeated physician evaluation during the procedure. It is not the code for a hemoperfusion treatment.
- 90935Hemodialysis
- 90935 is for hemodialysis with a single physician evaluation. Hemoperfusion uses an adsorbent cartridge rather than the hemodialysis method.
- 90999Unlisted dialysis procedure
- 90999 is the unlisted dialysis procedure code. Use the specific hemoperfusion code when the service performed is hemoperfusion.
90997 billing questions
How is hemoperfusion different from hemodialysis?
Hemoperfusion uses an adsorbent cartridge to remove selected substances from blood. Hemodialysis uses a different treatment method, so select the code that matches the service actually performed.
Is this reported once per treatment or once per day?
The code represents each hemoperfusion treatment. Document each treatment provided rather than counting separate physician evaluations as additional hemoperfusion services.
Does the 0-day global period include same-day care?
Yes. Same-day preoperative and postoperative care for the hemoperfusion procedure is included.
Can modifier 50 be used?
No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.
Can an assistant, co-surgeon, or surgical team be reported?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted.
