Family Medicine Billing Services · All 50 States
Most family medicine practices
are underbilling every single day
The 2021 E/M coding changes restructured how office visits are billed. Most practices responded by coding conservatively, and have been leaving up to $400,000 per physician per year on the table ever since. Zen finds it.

Preventive + problem-focused same day, both billable
The downcoding trap: Most family medicine practices consistently bill 99213 and 99214 out of caution, even when documented medical decision-making supports a 99214 or 99215. The revenue difference is $30–$80 per visit. At 20 visits per day, that is up to $400,000 per year per physician in systematically lost revenue.
Underutilized family medicine revenue streams
Chronic care management
CPT 99490 / 99491
Patients with 2+ chronic conditions receiving 20+ minutes of care coordination per month qualify. Most practices never bill this.
-
Significant monthly revenue per qualifying patient
Transition care management
CPT 99495 / 99496
For post-discharge patients contacted within 2 business days and seen within 7 or 14 days. Frequently missed entirely, pure revenue loss per patient.
-
Billed per qualifying post-discharge patient
Annual wellness visit
G0438 / G0439
Medicare Annual Wellness Visits have different CPT codes and documentation requirements than traditional preventive E/M. Mixing them causes systematic denials.
-
Covered at 100%, no patient cost-sharing
The billing challenge
Where family medicine revenue leaks
Family medicine practices see the highest patient volume of any specialty across the most diverse billing landscape, preventive care, sick visits, chronic disease management, procedures, and telehealth in the same day. Every category has its own denial risk.
Transition care management missed billing
TCM codes for post-discharge patients are frequently missed entirely, representing pure revenue loss for every qualifying patient who leaves the hospital.
Chronic care management billing
CCM services are consistently underutilized despite significant monthly revenue potential. Qualifying patients, two or more chronic conditions, 20+ minutes coordination, go unbilled.
Annual wellness visit confusion
Medicare Annual Wellness Visits and traditional preventive E/M visits have different CPT codes and documentation requirements. Mixing them causes systematic denials.
Preventive vs. problem-focused visit billing
When a preventive visit includes evaluation of a new problem, both services can be billed with Modifier 25. Most practices miss this split-billing opportunity every single day.
E/M downcoding
The most pervasive family medicine billing problem. Most practices consistently underbill complex visits, billing 99213 when 99214 or 99215 is documented and supported.
Telehealth place-of-service errors
Telehealth billing rules vary by payer and continue to evolve. Incorrect place-of-service codes trigger systematic denials across entire claim batches.
How Zen solves it
An E/M audit on day one, then optimization every day after

We apply the 2021 AMA E/M guidelines correctly to every visit and identify underutilized revenue streams specific to family medicine, CCM, TCM, annual wellness visits, and advance care planning.

Frequently asked questions
What to expect
What is E/M downcoding and how much is it costing my practice?
E/M downcoding happens when a physician bills a lower-complexity code when documented medical decision-making supports a higher one. The revenue difference is $30–$80 per visit. Across 20 visits per day, that is up to $400,000 per year per physician in lost revenue.
Does Zen bill for Chronic Care Management?
Yes. CCM is one of the most underutilized revenue streams in family medicine. Patients with two or more chronic conditions who receive 20 or more minutes of care coordination per month qualify. We identify eligible patients, manage the billing, and ensure documentation supports the service.
How do you handle preventive visit billing when the physician also addresses a problem?
We identify split-billing opportunities and bill both the preventive and problem-focused E/M correctly using Modifier 25, recovering revenue most practices leave on the table every single day.
Is there a long-term contract or commitment?
No. Zen operates month-to-month. We sign a BAA before accessing any PHI. We start with an E/M audit and show you exactly what you have been leaving behind, before you commit to anything.
