Chronic care management billing, covered under CPT codes 99490, 99439, 99487, 99489, and 99491, pays a practice for non-face-to-face care coordination furnished to a Medicare patient with two or more chronic conditions. The service is billed for minutes of work documented after the fact, which is what makes it a recurring audit target. A reviewer working a sampled claim checks three things: whether the required care coordination minutes were actually logged, whether the patient's consent is on file, and whether the required care plan exists and was shared with the patient. A practice that cannot produce all three for one claim in a sample risks a recoupment demand extrapolated across every CCM claim billed, part of a broader Medicare audit exposure that turns one sampled claim into a repayment figure far larger than the claim itself.
Three Requirements Every CCM Claim Must Meet
CMS's Chronic Care Management Services MLN booklet (MLN909188) sets the framework a claim has to satisfy. CPT 99490 covers the first 20 minutes of non-complex CCM per calendar month furnished by clinical staff under general supervision, with 99439 as the add-on for each additional 20 minutes. CPT 99491 requires 30 minutes of the billing practitioner's own personal time; clinical staff time does not count toward that code. Complex CCM under 99487 requires the first 60 minutes of clinical staff time plus moderate or high complexity medical decision-making, with 99489 for each additional 30 minutes. Before any of these codes can be billed, Medicare requires an initiating visit, the patient's written or verbal consent documented in the record, and a care plan built from a full physical, mental, cognitive, psychosocial, functional, and environmental assessment.
Time Records That Do Not Hold Up
The most common CCM audit finding is a time log that cannot support the code billed. An entry that says only "care coordination performed," with no start and stop time, no staff member identified, and no description of the work, is a reconstruction after the fact, and reviewers treat it that way. A second pattern is billing 99491 on the strength of clinical staff time, when that code counts only time spent personally by the billing practitioner. A third is billing the same minutes twice, once under CCM and again under transitional care management or remote monitoring, when CMS's concurrent billing rules do not allow time to count toward more than one service code. A fourth, documented in a 2021 OIG report on CCM overpayments (report A-07-19-05122), is two practitioners billing CCM for the same patient in the same calendar month, when only one may bill and be paid for it.
Consent Files And Care Plans That Fall Short
A signed consent is not optional paperwork. The record has to show the patient was told CCM was available, the cost-sharing involved, that only one practitioner can bill it per month, and that the patient can stop the service at any time effective at month's end. Practices relying on an intake form signed years earlier, with no note of what was actually explained, frequently cannot produce that record on request. The care plan fails for a related reason: a generic template with the same problem list and goals copied across patients is not patient-centered, and a plan that was created but never given to the patient fails the sharing requirement. A Recovery Audit Contractor reviewing a CCM sample treats a boilerplate care plan the same way it treats a missing one.
A note that says care coordination was performed is not a time log. Auditors want the start and stop time, the staff member who did the work, and what was done in those minutes, for every month billed.
Why Early Legal Counsel Is Critical
It is critical that practices retain healthcare defense counsel as soon as a Medicare Administrative Contractor requests records for a CCM claim, rather than after a denial or recoupment letter arrives. Early legal involvement can shape how the practice responds to an additional documentation request, identify which sampled claims are actually defensible, and prevent an isolated gap from becoming the basis for a broader payment suspension or a SMRC audit. Delaying counsel narrows the available defenses and can turn a single-claim finding into an extrapolated liability.
How Health Law Alliance Can Help
Health Law Alliance has overseen 2,000+ audits for practices and pharmacies facing Medicare and Medicaid review, including CCM claims caught in Part B audit sweeps. Our bench includes a former federal prosecutor and a former senior pharmacy benefit manager executive, background that shapes how we assess a CCM documentation file before a contractor does. If your practice has received a records request touching CCM billing, or wants its time logs, consent files, and care plans reviewed before an auditor asks for them, contact us for a free, confidential consultation.
