Many providers intentionally under-code to a 99214 out of fear of a Medicare RAC audit. However, if the patient's condition warrants high-complexity decision making, CPT 99215 is absolutely justified.
When to Bill 99215
To support a 99215, the Medical Decision Making (MDM) must be "High". You must meet 2 of these 3 criteria:
- 1 or more chronic illnesses with severe exacerbation, progression, or side effects of treatment, OR 1 acute or chronic illness that poses a threat to life or bodily function.
- Extensive amount and/or complexity of data to be reviewed.
- High risk of morbidity from additional diagnostic testing or treatment (e.g., decision for major surgery, drug therapy requiring intensive monitoring for toxicity).
Medical Necessity
The diagnoses on the claim must reflect severe or highly complex conditions. Routine hypertension without exacerbation will instantly fail a 99215 audit.
Billing with Prolonged Services
If you bill 99215 based on time (40-54 minutes), and you exceed 55 minutes, you may be eligible to bill a prolonged service add-on code. Run an NCCI check to ensure correct modifier usage.
