For FFS you don't need more than 4 diagnoses
But in SoCal with our managed care (and soon with ACO's) you will benefit from coding all of the applicable diagnoses with HCC codes as reimbursement will increase if you document the medical conditions a patient has.
Simple diabetes 250.00 is not as complex as diabetes with renal impairment-250.40, 583.81, Old MI- 412, depression 296.20, etc.
Many elderly have several of these HCC conditions that impact reimbursement and need to be billed annually so having room for 8 is an advantage.
