99205 CPT Code: New Patient Office Visit Billing Guide

The 99205 CPT code reports the highest-level office or outpatient evaluation-and-management visit for a new patient. Under the 2021 E/M rules you qualify for it one of two ways: high-complexity medical decision making, or 60–74 minutes of total provider time on the date of the encounter. It is the new-patient counterpart to 99215, and because it pays the most in the new-patient family, it draws the closest payer review.

What is the 99205 CPT code? 99205 is the Current Procedural Terminology code for a new patient office/outpatient E/M visit requiring high-complexity medical decision making or 60–74 minutes of total time on the encounter date.

Undeny's Take

99205 is under-billed far more than it is over-billed. A genuinely new, complex intake — a patient with multiple active diagnoses, medications to reconcile, and records to review — routinely runs past an hour, yet clinicians reflexively bill 99204 because the higher code feels risky. The 2021 framework removed that risk: you can support 99205 on total time alone, counting the chart review and care coordination you do on the encounter date, not just the minutes in the room. Track total time or document high MDM cleanly, and bill the level the work actually reached.

What 99205 Documents

99205 covers a new patient's office or outpatient E/M service at the highest level. A patient is "new" when they have not received a face-to-face service from you or a same-specialty colleague in your group within the prior three years. Since 2021 the level is set by medical decision making or total time, not by history-and-exam bullet counts.

Selecting 99205 by Time or Complexity

You reach 99205 in one of two independent ways. By time: 60–74 minutes of total time on the encounter date, including non-face-to-face work such as reviewing outside records and coordinating care. By decision making: high-complexity MDM, which weighs the number and severity of problems, the amount and complexity of data reviewed, and the risk of the management options. Reimbursement follows each payer's fee schedule — Medicare from the code's RVUs on the Physician Fee Schedule. Use your contracted rate or the CPT estimator for a working figure.

Modifiers That Apply to 99205

• 95 — synchronous audio-video telehealth, with the matching place of service.
• 25 — significant, separately identifiable E/M when a procedure or add-on is performed the same day.
• For psychiatric intakes, a psychotherapy add-on may be reported when both services are documented.

Why 99205 Gets Downcoded

• Total time or high-complexity MDM not clearly documented, dropping the claim to 99204.
• Patient does not actually meet the three-year "new patient" definition.
• Telehealth modifier or place-of-service mismatch.
• Time counted that does not qualify (for example, work on a different date).

Adjacent New-Patient and E/M Codes

99205 tops the new-patient ladder (99202–99205). On the established-patient side, 99214 and 99213 are the workhorse follow-up levels. For a psychiatric intake with medical services, see 90792. Browse the full set under CPT codes.

Frequently Asked Questions

What are the requirements for 99205?

99205 requires either high-complexity medical decision making or 60–74 minutes of total time on the date of the encounter. Since 2021, you select the level by MDM or time rather than by history and exam elements.

What counts as a new patient for 99205?

A new patient is one who has not received a face-to-face professional service from you, or another physician of the same specialty and subspecialty in your group, within the past three years. If they have, an established-patient code such as 99214 applies instead.

What is the difference between 99204 and 99205?

Both are new-patient visits, but 99205 reflects high-complexity decision making or 60–74 minutes, while 99204 reflects moderate complexity or 45–59 minutes. The greater problem severity, data, risk, or time supports the higher code.

Does telehealth change how I bill 99205?

You can bill 99205 for a qualifying new-patient telehealth visit, appending modifier 95 for synchronous audio-video and using the place-of-service code your payer requires. The time or MDM standard is the same as for an in-person visit.
