How Medicare CCM Reimbursement Works in 2026 (And Why Your Practice Is Probably Leaving Money Behind)

← Back to Blog

Chronic care management is one of the most consistently under-billed Medicare services in primary care. Practices are doing the work — coordinating with specialists, managing medication lists, following up with high-risk patients — they're just not documenting it in a way that generates a claim. Here's what the 2026 reimbursement structure looks like, and where most practices are losing money.

The 2026 CCM rate structure:

• CPT 99490 — First 20 minutes of monthly care coordination for patients with 2+ chronic conditions: $66.13/month
• CPT 99439 — Each additional 20 minutes of monthly coordination: $50.44/month
• CPT 99487 — Complex CCM, first 60 minutes (substantial care plan revision required): $144.29/month
• CPT 99489 — Complex CCM, each additional 30 minutes: $78.16/month

A practice billing 99490 + 99439 for 100 patients generates $11,657/month — $139,884/year — for care coordination work most practices are already doing. The barrier isn't eligibility. Most primary care panels have abundant CCM-eligible patients (2+ chronic conditions is a low bar: diabetes + hypertension qualifies). The barrier is operational: tracking time, documenting activities, and generating a claim each month per patient.

The biggest revenue leak I see: Practices running RPM programs that don't bill CCM for the same patients. The OIG is specifically auditing time overlap between RPM and CCM — but overlap is only a problem when time is double-counted. When RPM time (data review) and CCM time (care coordination) are documented separately, both codes are billable for the same patient in the same month. A fully-billed patient on both programs generates $211+ monthly at 2026 rates.

The practices capturing this revenue have one thing in common: separate documentation workflows for RPM and CCM. They don't let the same 15 minutes of clinical thinking justify two codes. They build programs where the activities are genuinely distinct — and the billing reflects that reality.
