Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
