CPT 99490 in 2026: Rates, Requirements, and the Documentation Auditors Actually Check

The short answer: CPT 99490 pays a practice for at least 20 minutes a month of clinical staff care management for a patient with two or more serious chronic conditions. It needs consent, a care plan and a time log in the record. Use the documentation checklist before you bill.

| Code | Who does the work | Time per calendar month | |---|---|---| | 99490 | Clinical staff | First 20 minutes | | +99439 | Clinical staff | Each additional 20 minutes (up to twice) | | 99487 | Clinical staff, complex CCM | First 60 minutes | | +99489 | Clinical staff, complex CCM | Each additional 30 minutes | | 99491 | Billing practitioner personally | First 30 minutes | | +99437 | Billing practitioner personally | Each additional 30 minutes |

What CPT 99490 covers

CPT 99490 reimburses physician practices for at least 20 minutes of non-face-to-face clinical staff time, directed by a physician, NP, or PA, delivered to a patient with two or more chronic conditions expected to last at least twelve months. It’s the base code of every chronic care management program on Medicare. If you’re billing CCM at all, you’re billing 99490.

The 2026 national-average Medicare rate is approximately $66 per enrolled patient per month. Actual amounts vary by Medicare locality (the geographic adjustment) and payer contract. A 200-patient panel fully enrolled at the base code therefore nets roughly $13,200 per month to the practice, the figure most CCM pitches lead with.

What has to be true for 99490 to bill cleanly

Five conditions, every one required:

1. The patient has two or more chronic conditions expected to last at least twelve months (hypertension, Type 2 diabetes, COPD, CHF, CKD, depression, arthritis, dementia, the list is broad).
2. The patient is enrolled in Medicare Part B.
3. Documented consent is on file, the patient has agreed to receive CCM services, understands only one practitioner can bill CCM for them at a time, understands there may be cost-sharing, and can revoke at any time.
4. A comprehensive care plan exists in the EHR, problem list, treatment goals, medication management, coordination with outside providers.
5. At least 20 minutes of clinical staff time has been delivered in the calendar month, directed by the billing physician “incident to” supervision, and documented with a time log.

Miss any one of those and the claim is at risk.

The 20-minute floor is just that, a floor

20 minutes is the threshold to bill the base code. Most well-run programs spend 25-35 minutes per patient per month in practice, reconciling meds across specialists, following up on specialist appointments the patient missed, calling before refills run out, updating the care plan. The 20 minutes is a CMS billing requirement, not a service-level ceiling.

If you’re regularly going past 20 minutes, that’s where the add-on code comes in.

CPT 99439, the add-on

CPT 99439 reimburses each additional 20-minute increment of clinical staff time in the same calendar month for the same patient. 2026 rate is approximately $46. You can bill 99439 up to twice per patient per month, which lifts the per-patient-per-month revenue by ~70% when the clinical complexity justifies it. For a full side-by-side on documentation requirements and when to escalate to Complex CCM, see CPT 99439 vs. 99490: how the add-on code works.

The common pattern:

• Base (99490), most enrolled patients, 20-25 min
• Base + 1 add-on (99490 + 99439), patients with a recent hospital discharge, a specialist handoff, or an active medication change
• Base + 2 add-ons, rare; most of this volume is better billed under Complex CCM (99487 / 99489)

99490 is one of five Medicare care management programs your practice can bill. Each has its own eligibility rules and CPT codes.

What auditors actually look at

Medicare contractors audit CCM billing more often than practices expect. The three things that get programs clawed back (use the CPT 99490 documentation checklist to review each chart before you bill):

• Time logs that aren’t specific. “Reviewed care” for 20 minutes doesn’t cut it. Logs should name the activity (medication reconciliation, specialist follow-up, caregiver call) and the clinical context.
• Missing or late consent. Consent must precede the first billed month, documented in the chart. A retroactive consent won’t survive an audit.
• Stale care plans. A care plan written at enrollment and never updated reads as pro-forma. CMS expects the plan to evolve with the patient, quarterly updates at minimum, more often when the clinical picture changes.

What this means for revenue planning

The 2026 base rate × your enrolled patient count is the floor. The realistic number is 15-30% higher once you factor in add-on utilization on the subset of patients who genuinely need more time. For a 200-patient panel, that lifts $13,200 to $15,000-$17,000/month end-to-end.
