2025 HCPCS code A4690
Effective Date: N/A Medical And Surgical Supplies - Dialysis Equipment and Supplies Feed
Dialyzer, all types and sizes, for hemodialysis, each.
Medical necessity for a dialyzer is established by the diagnosis requiring hemodialysis (e.g., end-stage renal disease, acute kidney injury). Supporting documentation should include the diagnosis, the plan of care, and the physician's order for hemodialysis.
In simple words: This code represents an artificial kidney (dialyzer) used in dialysis machines to clean a patient's blood when their kidneys are not working.
This code represents a dialyzer, a component of a hemodialysis machine, used to filter a patient's blood outside the body. It is used for all types and sizes of dialyzers designed for hemodialysis.
Example 1: A patient with end-stage renal disease receives hemodialysis three times a week, requiring a new dialyzer for each session. Code A4690 is used for each dialyzer., A patient experiences acute kidney injury following a traumatic accident and needs temporary hemodialysis. The dialyzer used is billed under A4690., A patient on home hemodialysis uses a different type of dialyzer than those typically used in a clinic. Regardless of the type or size, A4690 is used.
Documentation should support the medical necessity of hemodialysis and specify the type and size of the dialyzer used, if relevant for specific circumstances.
