How many eligible patients in your panel still aren’t enrolled in a chronic care program? One of the most common billing gaps in CCM programs is straightforward: many practices document 25 to 35 minutes of monthly care coordination time but only bill the base 20-minute code, leaving the add-on code completely unbilled. On a 200-patient panel, capturing that add-on for even 60 percent of eligible patients can recover tens of thousands of dollars a year in revenue that has already been earned through documented clinical work.
Athenahealth CCM billing only performs well when time tracking, CPT code selection, and consent documentation are all configured correctly from the start. Because CCM and Principal Care Management (PCM) are both time-based, recurring monthly programs, small workflow gaps compound quickly across an entire patient panel.
This guide explains how CCM and PCM billing works, the specific time thresholds and CPT codes involved, how to document consent correctly, and how to turn these programs into a dependable recurring revenue stream inside Athenahealth.
What Are CCM and PCM Programs?
Chronic Care Management (CCM) and Principal Care Management (PCM) are Medicare programs that reimburse practices for non-face-to-face care coordination time spent managing patients with chronic conditions.
- CCM applies to patients with two or more chronic conditions expected to last 12 months or longer, or until the patient’s death.
- PCM applies to patients with a single high-risk chronic condition expected to last at least three months, such as advanced heart failure or complex diabetes.
CCM and PCM cannot be billed for the same patient in the same calendar month, so practices must evaluate each patient’s clinical profile to determine which program applies before enrollment.
How Athenahealth CCM and PCM Billing Works
A structured monthly workflow keeps CCM and PCM billing accurate and audit-ready.
- Eligibility Screening. Identify patients with qualifying chronic conditions during a visit or through a regular panel sweep.
- Initiating Visit. Document the upstream visit that establishes the need for ongoing care management. A first CCM claim without this on file triggers an automatic denial.
- Consent Collection. Obtain and document patient consent, which can be given verbally but must be logged with the date it was obtained.
- Care Plan Creation. Build a structured, electronically stored care plan inside Athenahealth, not a free-text note.
- Time Tracking. Log clinical staff or physician time spent on care coordination throughout the month.
- Code Selection. Choose the CPT code that matches both the total time logged and who performed the work.
- Monthly Billing. Submit the claim once the applicable time threshold is met, ensuring only one practitioner bills per patient per month.
Tracking Time Thresholds for Chronic Care Management
CCM is a time-based program, and the thresholds are strict enough that missing a few minutes of documentation can mean an entire add-on code goes unbilled.
The Base Threshold and the Add-On Code
CPT 99490 covers the first 20 minutes of clinical staff time per month for qualifying CCM patients, reimbursing approximately $62 per patient. Once staff time passes that 20-minute mark, CPT 99439 covers each additional 20-minute increment, reimbursing approximately $47.
Why the Add-On Code Gets Missed
Staff frequently log the additional time in a note but don’t flag it for the add-on code during claim submission. This is a workflow gap rather than a coding complexity issue, and it’s typically fixable with a time-tracking prompt built directly into the Athenahealth care management workflow.
CPT Codes for Principal Care Management
PCM uses a different set of codes than CCM, split by who actually performs the care coordination work.
| CPT Code | Description | Performed By | Approx. Reimbursement |
| 99424 | First 30 minutes per month | Physician or QHP | ~$88 |
| 99425 | Each additional 30 minutes | Physician or QHP | ~$61 |
| 99426 | First 30 minutes per month | Clinical staff, general supervision | Lower than 99424 |
| 99427 | Each additional 30 minutes | Clinical staff, general supervision | Lower than 99425 |
Codes 99424 and 99426 are mutually exclusive. The correct code depends on who primarily performed the care coordination work that month, not on practice preference.
CCM vs PCM Comparison
Choosing the right program for each patient prevents denials tied to mismatched eligibility.
| Feature | CCM | PCM |
| Eligible conditions | Two or more chronic conditions | One high-risk chronic condition |
| Minimum condition duration | 12 months or longer | 3 months or longer |
| Base time threshold | 20 minutes (staff) or 30 minutes (physician, 99491) | 30 minutes |
| Can stack with RPM | Yes | Yes |
| Can stack with BHI | Yes | No |
| Can bill same patient, same month as the other | No | No |
Primary Care Recurring Revenue Strategies
CCM and PCM convert ongoing care coordination into predictable monthly revenue instead of relying solely on visit-based billing.
Building a Consistent Enrollment Pipeline
Run a regular eligibility sweep across the full patient panel to identify qualifying patients who haven’t been enrolled yet. Unenrolled but eligible patients are often the single largest revenue gap in a chronic care program, since eligibility frequently goes unflagged during a standard visit.
Stacking Programs Where Permitted
CCM can be billed alongside Remote Patient Monitoring (RPM) and Behavioral Health Integration (BHI) in the same month, provided the time logged for each program is kept separate and not double-counted. PCM can stack with RPM but not with CCM. Understanding these combinations allows practices to build multiple recurring revenue streams around the same patient population.
Documenting Patient Consent for CCM in EHR
Consent documentation is a hard compliance requirement, not a formality, and it’s one of the first things reviewed during an audit.
What Qualifies as Valid Consent
Consent can be obtained verbally, but it must be documented in the medical record along with the date it was given. A claim without documented consent on file is a common and preventable reason for denial or recoupment, regardless of whether the underlying clinical work was performed correctly.
Structured Documentation Requirements
Care plans must exist as structured data inside the certified EHR, not as a note in a free-text field or a separate document. A care plan that isn’t properly structured in Athenahealth fails certified-EHR requirements and puts the associated claim at risk during review.
Common Billing Errors That Reduce CCM and PCM Revenue
Recognizing these errors early prevents avoidable denials and recovers revenue that’s often already been earned through documented clinical work.
Time Tracking Errors
Common time tracking issues include:
- Logging time without flagging it for the applicable add-on code
- Missing the minimum threshold by a few minutes due to inconsistent logging
- Counting overlapping time across CCM, PCM, and RPM for the same activity
- Failing to reset time tracking at the start of each new calendar month
Documentation and Consent Errors
Common documentation issues include:
- Missing or undated consent in the medical record
- Free-text care plans instead of structured EHR data
- No documented initiating visit before the first CCM claim
- Care plans not updated to reflect a patient’s current condition
Program Selection Errors
Common program selection issues include:
- Billing CCM and PCM for the same patient in the same month
- Enrolling a single-condition patient in CCM instead of PCM
- Multiple practitioners billing CCM for the same patient in the same month
- Continuing CCM billing after transitioning a patient into TCM without observing the required gap
Outsourced Medical Billing for Value-Based Care
CCM and PCM billing is detail-intensive, and small errors compound quickly across an entire patient panel.
Why This Work Suits an Outsourced Model
Tracking monthly time thresholds, selecting the correct code per patient, and keeping consent and care plan documentation audit-ready requires ongoing attention that most in-house teams struggle to sustain alongside daily clinical operations. A billing partner focused specifically on value-based care programs can run these checks consistently, rather than catching gaps only after a denial or audit occurs.
What Outsourced Support Typically Covers
A dedicated billing partner typically runs eligibility sweeps to identify unenrolled patients, monitors monthly time logs to catch missed add-on codes, and audits consent and care plan documentation before claims are submitted. This turns CCM and PCM from a manual, error-prone process into a dependable monthly revenue stream.
Conclusion
Athenahealth CCM billing rewards precision at every step. The time thresholds are strict, the CPT codes are split based on who performed the work, and both consent and care plan documentation have to hold up under audit scrutiny. Most of the revenue practices left on the table aren’t the result of doing clinical work incorrectly. It comes from under-billing time that was already spent, missing eligible patients during enrollment, or letting documentation fall short of certified-EHR requirements.
Getting these details right consistently turns CCM and PCM into one of the more reliable recurring revenue streams available to a primary care practice, particularly as value-based care programs continue to expand.
FAQs
Can a practice bill both CCM and PCM for the same patient?
No. The two programs are mutually exclusive in the same calendar month. If a patient has multiple chronic conditions, CCM is usually the better fit. If a single condition dominates the clinical picture, PCM applies instead.
Who can perform the clinical staff time for CCM and PCM?
Clinical staff, including RNs, LPNs, and experienced medical assistants, can perform the work under general supervision for codes 99490, 99439, and 99426. The billing practitioner doesn’t need to perform the work personally, but only they can submit the claim.
What happens if patient consent isn’t documented?
The claim becomes a denial or recoupment risk, even if the clinical work itself was completed correctly. Consent can be given verbally, but it must be logged in the record along with the date it was obtained.
Can CCM be billed alongside Remote Patient Monitoring?
Yes. CCM and RPM can be billed concurrently for the same patient in the same month, provided the time logged for each program doesn’t overlap.
Is a free-text care plan acceptable for CCM billing?
No. A care plan stored as a note or in a separate document doesn’t meet certified-EHR requirements. It must exist as structured data inside Athenahealth to hold up during an audit.
