CCM Billing Codes & Requirements: 2026 Guide

By Dynamic Medical Billing Solutions · Updated November 7, 2026 · 8 min read

Chronic care management pays practices for work they already do — coordinating care for patients with two or more chronic conditions. Yet many practices bill it rarely, and when they do, claims fail on simple rules: 19 minutes instead of 20, the wrong code family, a consent note never documented. This guide covers the six codes, the time thresholds, and the documentation Medicare expects in 2026.

What CCM Is — and Why Practices Under-Bill It

Chronic care management (CCM) is Medicare's payment for non-face-to-face work between visits: reviewing records, reconciling medications, coordinating with specialists, following up, and keeping the care plan current. It is billed once per patient per calendar month, to one practitioner only.

Base amounts are modest — roughly $66 to $144 per patient per month — but they scale across a panel. Practices under-bill CCM for three reasons: unlogged time, unscreened eligibility, uncaptured consent. Fix those three and CCM becomes repeatable monthly revenue — the workflow our chronic care management billing services are built around.

Who Qualifies: Eligibility and Consent

A patient qualifies with two or more chronic conditions expected to last at least 12 months (or until death) that put them at significant risk of death, acute exacerbation or decompensation, or functional decline.

• Consent — document patient consent before billing, written or verbal, once (a new consent is needed only if the patient switches CCM practitioners). It must cover cost-sharing — deductible and coinsurance apply — and the one-practitioner-per-month rule.
• Care plan — a comprehensive care plan must be established, implemented, revised or monitored, and kept in the record.
• Supervision — clinical-staff codes are billed under general supervision; the billing practitioner need not be physically present.

The Six CCM Codes at a Glance

Code	Whose time	Minutes	2026 approx. rate*
99490	Clinical staff	First 20 minutes	~$66
99439	Clinical staff (add-on to 99490)	Each additional 20 minutes, up to 2 units	~$50 each
99491	Billing practitioner personally	First 30 minutes	~$89
99437	Billing practitioner personally (add-on to 99491)	Each additional 30 minutes	~$63
99487	Clinical staff	First 60 minutes + moderate- or high-complexity MDM	~$144
99489	Clinical staff (add-on to 99487)	Each additional 30 minutes	~$78

*Approximate 2026 Medicare national non-facility amounts — actual payment varies by locality (GPCI). Confirm current amounts in the CMS fee schedule.

The key threshold is 99490's: a full 20 minutes of clinical staff time per month. A month with 19 minutes is not billable — no partial credit.

How the Three Code Families Stack — and Never Mix

The six codes form three families. The golden rule: pick one family per patient per month — do not mix families in the same month.

• Family 1 — clinical staff time: 99490 for the first 20 minutes, then 99439 per additional 20 minutes (up to 2 units). Example: 45 minutes bills as 99490 plus one unit of 99439.
• Family 2 — billing practitioner personally: 99491 for the first 30 minutes the practitioner spends personally, then 99437 per additional 30 minutes. Staff time does not count here.
• Family 3 — complex CCM: 99487 for the first 60 minutes of clinical staff time plus moderate- or high-complexity decision-making by the billing practitioner personally, then 99489 per additional 30 minutes. Example: 90 minutes bills as 99487 plus one unit of 99489.

Add-on pairings are fixed: 99439 only with 99490, 99437 only with 99491, 99489 only with 99487. Billing 99437 as an add-on to 99490 will be denied.

The Initiating Visit and the Care Plan

Before CCM billing starts, an initiating visit is required for new patients and patients not seen in the previous year: a comprehensive face-to-face visit — an evaluation and management visit, an annual wellness visit (AWV), or an initial preventive physical exam (IPPE) — billed separately, not as CCM minutes.

The care plan is the other foundation document: comprehensive, established for the patient, then implemented, revised or monitored, and available in the record. Date of service matters too: for 99490/99491, use the date the threshold was met; complex CCM is billed at month end.

Time Tracking and Documentation That Survives an Audit

CCM is time-based, so the time log is the claim. Every billable month needs a per-patient log — date, minutes, who did the work, what was done. Unlogged time cannot be billed, and time without a matching note will not survive an audit.

• Log time daily — end-of-month reconstruction is where minutes get invented or lost.
• Separate staff time from practitioner time — they belong to different code families.
• Keep the consent note and care plan filed, so any month's claim can be defended from the chart alone.
• Review the log before submission: threshold met, right family used, add-on units matching the minutes.

A billing audit of CCM claims usually finds the same three gaps — unlogged minutes, missing consent, family-mixing — and a dedicated CCM billing workflow closes them.

What You Can (and Can't) Bill in the Same Month

• Transitional care management (TCM) — CCM can be billed in the same month as TCM, when both are furnished and documented.
• Principal care management (PCM) and advanced primary care management (APCM) — CCM cannot be billed by the same practitioner in the same month as PCM or APCM. Pick one program per patient.
• One practitioner only — only one practitioner may bill CCM for a given patient in a calendar month. If another practice is already billing it, your claim will be denied.
• Face-to-face visits — office visits and the initiating visit are billed normally alongside CCM; CCM covers the coordination between them.

Check conflicts before submission, not after the denial.

Common CCM Denial Reasons and How to Fix Them

• Under-20-minute months — 19 minutes bills nothing. Bill the month only when the threshold is met.
• Mixed code families — 99490 with 99491 or 99487 for the same patient in one month. Choose one family.
• Wrong add-on pairing — 99437 with 99490 (pairs only with 99491); 99439 with 99487 (pairs only with 99490).
• Missing consent documentation — document consent once, before billing, and file it.
• No care plan on file — establish the plan at enrollment; a claim without one is indefensible.
• Missing initiating visit — a new patient billed for CCM without the required face-to-face visit first.
• Double-billing with PCM or APCM — same practitioner, same month. Choose one program per patient per month.
• Time not tracked — minutes claimed with no log behind them. Log daily, per patient.

Most CCM denials are preventable before submission. Dedicated denial management can work the backlog, and a small-practice billing setup that logs time as the work happens stops most of these at the source.

CCM Billing Checklist

1. Screen the panel for patients with two or more qualifying chronic conditions.
2. Obtain and document patient consent, including cost-sharing and the one-practitioner rule.
3. Complete the initiating visit where required (new patient, or not seen in the past year).
4. Establish the comprehensive care plan and file it in the record.
5. Log time daily, per patient — date, minutes, who, what.
6. At month end, match the minutes to one code family and its threshold (20/30/60 minutes).
7. Use the correct add-on pairings only: 99439 with 99490, 99437 with 99491, 99489 with 99487.
8. Check same-month conflicts — no PCM/APCM from the same practitioner; no other practitioner billing CCM.
9. Set the date of service — threshold date for 99490/99491, month end for complex CCM.
10. Submit, then review denials monthly and fix the workflow that caused them.

Frequently Asked Questions

How many minutes do I need to bill 99490?

A full 20 minutes of clinical staff time in the calendar month. A month with 19 minutes is not billable — no partial credit.

Can I bill 99437 with 99490?

No. Add-on 99437 pairs only with 99491. With 99490, the add-on is 99439 — each additional 20 minutes, up to 2 units.

When is complex CCM (99487) the right code?

When the month involves the first 60 minutes of clinical staff time plus moderate- or high-complexity decision-making by the billing practitioner. Its add-on is 99489, one unit per additional 30 minutes.

Can CCM and transitional care management be billed in the same month?

Yes, when both are furnished and documented. What CCM cannot share a month with — same practitioner — is principal care management or advanced primary care management.

Does the patient need to consent to CCM?

Yes. Documented consent — written or verbal — is required before billing, covering cost-sharing and the one-practitioner-per-month rule. It is obtained once; a new one is needed only if the patient switches CCM practitioners.
