Principal Care Management

PCM Period: Calendar month Source: CMS-1827-F (CY 2026 PFS Final Rule)

What it is

Principal Care Management (PCM) is a Medicare benefit for patients with a single complex chronic condition that places them at risk of decompensation, acute exacerbation, or functional decline. PCM differs from CCM in that PCM focuses on the management of one condition, often by a specialist — a cardiology HF panel, a nephrology CKD panel, an endocrinology T2DM panel.

Billed monthly in 30-minute tiers.

Codes & when to bill them

How the minutes add upBill 99426 at 30 minutes of clinical-staff time, then 99427 for each additional 30 minutes — one at 60 minutes (max two add-ons). Time the billing physician performs personally is billed instead as 99424 (first 30 min) + 99425.

Each billable code, with the requirements that must be on file to bill it.

Documentation required every cycle

Each calendar month must show:

  1. Total clinical staff or practitioner time spent on PCM (rounded to the minute).
  2. Condition-specific care plan documenting the focused intervention.
  3. Care coordination with the patient's PCP and other treating clinicians.
  4. Patient consent on file with version, date, and capture method.
  5. Practitioner sign-off at month close.

What's new in CY 2026

CY 2026 retains the PCM code set. PCM may be concurrent with CCM only when billed by different practitioners; the same practitioner cannot bill both for the same patient in the same month for overlapping condition management.

Built-in patient consentWillowbridge exclusive

Every program ships with compliant, CY-2026 patient consent language — read verbatim into the in-app consent capture flow, captured with date + modality, and version-pinned to each claim, so the consent on file always matches the consent that was billed. No more chasing signatures or re-papering when the rule changes.
