APCM Billing Codes Compliance & Audit Readiness Checklist

Confirm the patient has at least two or more chronic conditions expected to last at least 12 months for G0556 or G0557 eligibility.

Check Medicare eligibility files to confirm Qualified Medicare Beneficiary status before billing the G0558 code variant.

Ensure a face-to-face initiating visit (AWV or E/M) occurred within the last 12 months before starting APCM services.

Obtain and document verbal or written consent, informing the patient of cost-sharing and their right to stop the service at any time.

Review patient risk scores and social determinants of health to determine if the patient meets high-complexity criteria for G0557.

Verify the patient is not currently enrolled in or being billed for CCM, PCM, or TCM services by another provider in the same month.

Maintain logs proving patients have 24/7 access to care team members for urgent needs, which can be facilitated by AI call handling.

Develop a comprehensive, person-centered care plan in the EHR that is accessible to all members of the care team.

Document the systematic tracking and delivery of recommended preventive services based on the patient's age and health status.

Record all instances of medication reconciliation and adherence reviews conducted during the billing period.

Use AI to transcribe and summarize patient interactions, ensuring every minute of coordination is documented for audit trails.

Document follow-up activities after emergency room visits or hospital discharges, including timely outreach and summary exchange.

Ensure the POS code used on the claim matches the primary care setting where the physician typically treats the patient.

Use Modifier 25 if a significant, separately identifiable E/M service is performed on the same day as an APCM initiating visit.

Set system alerts to prevent billing more than one APCM code (G0556, G0557, or G0558) per patient per calendar month.

Prepare workflows for the 2026 introduction of behavioral health add-on codes G0568, G0569, and G0570.

Confirm the billing NPI belongs to a physician or non-physician practitioner authorized to bill for primary care services.

Run internal reports to ensure no overlapping claims for RPM (99457) or RTM unless specific service separations are documented.

Conduct a monthly review of a random sample of APCM claims to verify that all service elements were documented before submission.

Retain time-stamped records of all automated and manual patient communications to prove care coordination took place.

Maintain a dedicated log for G0556-G0558 denials to identify patterns in payer rejections and update coding logic.

Provide quarterly training to billing staff on the nuances between G0556 and G0557 to ensure accurate complexity coding.

Periodically review AI call scripts to ensure they meet CMS requirements for patient education and care coordination.

Verify if private Medicare Advantage plans have additional documentation requirements beyond the standard CMS final rule.
