The multiple patient focused care codes created by CMS and followed by many commercial payers requires a care plan strategy and billing strategy to optimize care and revenue.  For example PCM, has been expanded by CMS to support providers working with patients with just one high-risk condition allowing up to 60 minutes of billable time per month, by both clinical staff and providers.

The differences are easily seen in the billable codes.

Obviously if a patient has at least two chronic conditions, then Chronic Care Management (CCM) is a better choice for billable services.
