What 90959 covers

Code 90959 represents monthly management of end-stage renal disease for a patient age 12 through 19, with one face-to-face visit during the month. A nephrologist or other qualified clinician typically evaluates the patient in connection with ongoing dialysis care, reviews the clinical course and relevant results, and manages issues such as fluid status, dialysis adequacy, anemia, mineral and bone disorders, and vascular access. The service may be furnished in a dialysis facility or another appropriate clinical setting.

Select this code using the patient’s age category and the number of face-to-face visits provided during the month. The record should support the monthly ESRD management, the date and substance of the face-to-face evaluation, and the patient’s age. Report the monthly service once for the applicable month rather than treating each dialysis treatment as a separate monthly service. Distinguish this facility-based monthly series from the separate monthly codes for patients receiving home dialysis.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

90959 billing questions

When is 90959 chosen instead of 90958?

For a patient age 12 through 19, 90959 corresponds to one face-to-face visit during the month. Code 90958 is the sibling for two or three visits.

Does each dialysis treatment count as a visit for this code?

No. The code level is based on the number of face-to-face visits for monthly ESRD management, not the number of dialysis treatments performed.

Can 90959 be reported for each dialysis session?

No. It represents monthly ESRD-related management for the specified age and visit level, not a charge for each dialysis treatment.

What documentation supports reporting 90959?

Document the patient’s age, the date and substance of the face-to-face evaluation, and the ESRD-related management furnished during the month.

How does 90959 differ from the home dialysis monthly code?

90959 belongs to the monthly ESRD service series for the 12–19 age group and one face-to-face visit. Code 90965 is the corresponding monthly code for a home dialysis patient in that age group.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
