Place of Service Code 65: End Stage Renal Disease Treatment Facility
What is Place of Service Code 65?
POS 65 designates a facility specializing in end-stage renal disease (ESRD) treatment, such as a dialysis center. This POS is rarely encountered in standard mental health billing but may apply when a behavioral health provider delivers therapy to dialysis patients within the treatment facility itself.
When to Use POS 65
Use POS 65 only when providing mental health services — such as an individual therapy session — physically delivered inside a dialysis or ESRD treatment center. Most outpatient therapists will never bill this code.

Common Mistakes with POS 65
- ✗Billing POS 11 for therapy actually delivered inside a dialysis center

- ✗Neglecting to verify payer authorization for mental health services in an ESRD setting
- ✗Using POS 65 for telehealth sessions with ESRD patients who are at home — use POS 10 instead
