What 90964 covers
This code represents a month of physician management for a child ages 2 through 11 receiving home dialysis. A nephrologist typically assesses the child’s dialysis-related status, reviews treatment and laboratory information, and manages issues such as fluid balance, blood pressure, medications, vascular access, and dialysis complications. Care may involve coordination with the family and the home dialysis team in an outpatient setting.
Select the code based on the patient’s age and home-dialysis status for the month. Documentation should support the patient’s age, home dialysis, and the physician’s ESRD-related management during that month. This is a monthly service code, not a code for each home dialysis session. For a partial month, compare the circumstances with the applicable per-day ESRD service code rather than treating this as a per-session service.
