What 90966 covers

This code represents a month of ESRD-related management for an adult receiving dialysis at home, such as home hemodialysis or peritoneal dialysis. A nephrologist or other qualified clinician manages the patient’s dialysis care, assessing clinical status and addressing the treatment plan, relevant results, and related care needs. Services may be furnished through an outpatient nephrology practice while the patient performs dialysis at home.

Select the code based on the patient’s age and home dialysis setting, not on the number of monthly visits. Documentation should identify the home modality and support the ESRD-related assessment and management furnished during the month. For a patient age 20 or older whose ESRD services cover only part of a month, consider the age-matched per-day code rather than reporting this monthly service as a visit-count level.

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.

90966 billing questions

Does the number of visits during the month determine whether 90966 applies?

No. The monthly home dialysis code is selected by age and dialysis setting, rather than by the visit-count levels used for in-center ESRD services.

How does 90966 differ from 90965?

Both are monthly home dialysis management codes; 90966 is for patients age 20 or older, while 90965 is for patients ages 12 through 19.

What code is used when home dialysis services cover only part of a month?

For a patient age 20 or older, the per-day counterpart is 90970. Use the code that reflects the patient’s age and the service period.

Is 90966 for home hemodialysis, peritoneal dialysis, or both?

It applies to home dialysis management, including home hemodialysis and peritoneal dialysis.

What should the record support?

Document the patient’s age, home dialysis modality, month of management, and the ESRD-related assessment and management provided.

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.
