What 90958 covers

This monthly service covers a physician’s or qualified health care professional’s management of a patient ages 12 through 19 receiving treatment for end-stage renal disease. A nephrologist commonly provides the visits in a dialysis facility, hospital, or office, addressing the patient’s dialysis plan and related clinical needs, such as treatment response, laboratory findings, medications, and dialysis-related complications. The code’s visit tier is based on two or three face-to-face visits during the month, not on the number of dialysis sessions the patient receives.

Report the monthly code when the patient’s age and documented face-to-face visit count match this tier. The record should identify the services and visit dates supporting ongoing ESRD management. It is one monthly service, not a separate unit for each encounter or dialysis treatment. CMS payment is based on the physician fee schedule values for this code.

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.

90958 billing questions

How does 90958 differ from 90957?

Both are monthly ESRD management codes for patients ages 12 through 19. Use 90958 for two or three face-to-face visits; 90957 is the four-visit tier.

Can 90958 be reported when there is only one face-to-face visit?

No. The one-visit monthly tier for a patient ages 12 through 19 is 90959.

Do dialysis sessions count as the face-to-face visits?

The tier is based on face-to-face visits for monthly ESRD management, not simply the number of dialysis treatments. Document the management encounters and their dates.

What code applies if ESRD services cover only part of the month?

90969 is the per-day ESRD services code for patients ages 12 through 19. It differs from 90958’s monthly visit-count tier.

Is 90958 reported once for each visit?

No. It represents the monthly service at the two-to-three-visit level, rather than a separate unit for each face-to-face encounter.

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.
