What is CPT 99489 used for?
CPT 99489 is the add-on for additional complex CCM time. After the first 60 minutes billed with 99487, each further full 30-minute block of clinical staff time in the same month is reported with 99489. It lets the most resource-intensive complex-CCM patients generate revenue proportional to the coordination effort.
Because it is an add-on, 99489 never stands alone; it attaches only to the complex CCM base code 99487. It cannot be reported with non-complex CCM codes (99490, 99439) or with the physician-personal CCM code 99491 for the same patient in the same month, because a patient sits in exactly one CCM family per month.
How much does 99489 pay in 2026?
99489 carries 2.34 non-facility RVUs and 1.31 facility RVUs. At the 2026 conversion factor of $33.4009 that is about $78.16 non-facility and $43.76 in a facility per 30-minute unit. Stacked on 99487, a 90-minute complex CCM month reaches roughly $222 non-facility. Model the stacked monthly total on the Medicare fee calculator.
How does 99489 stack on complex CCM?
| Staff time in month | Codes | 2026 non-facility total |
|---|---|---|
| 60 min | 99487 | ~$144.29 |
| 90 min | 99487 + 99489 | ~$222.45 |
| 120 min | 99487 + 99489 x2 | ~$300.61 |
Example: a complex-CCM patient generates 85 documented staff minutes in a month; that supports 99487 plus one 99489, about $222.45, but not a second add-on, because the extra 25 minutes falls short of a full 30-minute increment. Push that same patient to 95 documented minutes and the month supports 99487 plus two 99489 units, roughly $300.61, since the extra 35 minutes contains one complete 30-minute block beyond the first add-on.
The add-on inherits the base code's clinical bar: the month must still reflect moderate- to high-complexity decision making and substantial care-plan work, not just accumulated minutes. If a reviewer re-maps the month to non-complex CCM, the 99489 units fall with the base code, so the documentation supporting complexity is what protects the whole claim.
Frequently asked questions
99489 is an add-on reported only with base code 99487 for each additional full 30 minutes of clinical staff time in complex chronic care management beyond the first 60 minutes in a calendar month. Each unit requires a complete 30-minute increment, documented with dated activities.
The 2026 national non-facility allowed amount is about $78.16 (2.34 total RVUs times $33.4009) and about $43.76 in a facility per 30-minute unit. Stacked on 99487, a 90-minute complex CCM month reaches roughly $222 non-facility.
No. 99489 attaches only to complex CCM base code 99487. Do not report it with non-complex CCM (99490, 99439) or with the physician-personal CCM code 99491 for the same patient in the same month. Choose one CCM family per patient per month.
