What 90956 covers

This code represents monthly ESRD-related care for a patient who is 2 through 11 years old and receives one face-to-face visit during the month. A nephrologist commonly provides the visit in a dialysis setting, reviewing the child’s clinical course and addressing ESRD management needs such as dialysis tolerance, fluid status, laboratory findings, medications, and growth or nutrition concerns. It represents monthly care, not a separate evaluation for each dialysis treatment.

Select the code by the patient’s age and the number of face-to-face visits furnished in the month. Documentation should support the patient’s age, the date and substance of the visit, and the ESRD-related management performed. Use the corresponding sibling when the monthly visit count or age band differs; the home-dialysis monthly series and per-day services describe different circumstances. CMS assigns physician fee schedule values to this service.

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.

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.
