CPT Code 99205: New Patient Office Visit (Level 5) — Complete Billing and Coding Guide
What Does CPT Code 99205 Mean?
CPT code 99205 describes a level 5 new patient office or other outpatient visit that involves a high level of medical decision making (MDM). This is the highest-level new patient E and M code in the outpatient evaluation and management set (99202-99205) and is used when a new patient presents with a severe exacerbation of a chronic condition, a new problem posing a threat to life or functional capacity, or an acute illness requiring extensive workup and high-risk management.
Key Code Attributes:
- Billable Status: Fully billable for new patient encounters with high-complexity MDM
- Primary Setting: Office or other outpatient setting
- Provider Type: MD/DO, NP, PA, CNM, CNS (any licensed provider)
- Visit Type: New patient (not seen by same specialty in same group within past 3 years)
- MDM Level: High complexity
- Time Threshold: 60-74 minutes total time (if time-based)
- Medicare Payment: ~$210-260 (non-facility, 2026 estimated)
- Audit Risk: High — most frequently downcoded new patient code
What Services and Procedures Does CPT Code 99205 Cover?
CPT 99205 encompasses new patient encounters where the presenting problem is of high severity and requires high-complexity MDM — representing the most extensive new patient evaluation involving conditions that pose a significant threat to life, bodily function, or quality of life.
Covered Clinical Presentations (Examples):
- New patient with suspected stroke or TIA requiring urgent neurologic evaluation and imaging
- New-onset chest pain with abnormal EKG findings requiring cardiac workup and stress testing
- New patient with severe COPD exacerbation requiring pulmonary function assessment, oxygen therapy, and specialist referral

Prior Authorization / LCD
No specific LCD for 99205. Key denials:
- “New patient status not verified” — verify 3-year rule
- “Medical necessity not supported” — high MDM must be clearly documented with all three data elements
- “Downcoded to 99204” — most common audit outcome when high MDM not clearly justified
- “Insufficient documentation of threat to life or function” — must clearly describe severity
What Codes Are Commonly Billed With CPT 99205?
| Code | Description | Guidance |
|---|---|---|
| -25 modifier | Same-day procedure | Append -25 to 99205 |
| G2211 | Complex visit add-on | Append to 99205 |
| 93000 | EKG | Bill separately |
| 93015 | Cardiovascular stress test | Bill separately |
| 80053 | Comprehensive metabolic panel | Bill separately |
| 85025 | Complete blood count | Bill separately |
NCCI Edits: No bundling conflicts with -25 on 99205. G2211 is add-on only.
Common Coding Errors
- Using 99205 for established patients — Verify 3-year new patient rule before using 99205
- Upcoding 99204 to 99205 — Must have ALL THREE data elements and high risk. Chronic exacerbation without threat to life = 99204
- Missing data elements — 99205 requires external records review AND independent test interpretation AND test ordering. Missing one element drops to 99204
- Insufficient risk documentation — High risk requires explicit documentation of threat to life, major surgery decision, or parenteral controlled substance management
- Time misdocumentation — Must document total time and confirm greater than 50% counseling time for time-based coding
- Missing -25 modifier — Procedure same day without -25 results in denial
- Payer-specific restrictions — Some commercial payers require preauthorization for 99205
Real-World Coding Scenario
Patient: A 72-year-old male new to the practice presents via urgent appointment with 2-hour history of sudden-onset left arm weakness, facial droop, and slurred speech that began resolving during transport. He has a history of hypertension, diabetes, and atrial fibrillation not currently on anticoagulation. Provider reviews outside records from his prior cardiologist (confirming history of paroxysmal AFib), independently interprets the stat CT head (negative for hemorrhage), interprets the EKG (rate-controlled AFib), and orders MRI brain, carotid ultrasound, echocardiogram, troponin, and comprehensive labs. Provider discusses risks and benefits of anticoagulation, initiates apixaban, counsels on stroke warning signs, and coordinates follow-up with neurology and cardiology. Total time: 68 minutes, 40 minutes counseling.
Correct Code: CPT 99205
- High MDM: Acute illness posing threat to life/function (TIA/stroke)
- Data: ALL THREE elements present — external records review (cardiology records) + independent test interpretation (CT head, EKG) + test ordering (MRI, labs, echo)
- Risk: High — drug therapy requiring intensive monitoring (apixaban for stroke prevention with bleeding risk)
- Time-based also supports 99205 (68 min within 60-74 min range, greater than 50% counseling)
Common Mistake: Using 99204 — this visit has ALL THREE data elements plus high risk (anticoagulation decision in elderly patient with fall risk), clearly supporting 99205 over 99204.
Frequently Asked Questions
Is CPT 99205 Still Valid for 2026?
Yes. CPT 99205 remains active with no changes to its descriptor, RVU values, or guidelines since the 2021 E and M overhaul. Verify annually against AMA CPT updates and CMS MPFS.
What Is the Difference Between 99205 and 99204?
99205 requires high MDM with ALL THREE data elements present (external records review AND independent test interpretation AND test ordering), plus high risk (threat to life/function, major surgery decision, parenteral controlled substances, or hospitalization). 99204 requires moderate MDM with only ONE data element and moderate risk. Time threshold is 60-74 min vs. 45-59 min.
Can I Bill 99205 With a Preventive Visit?
Yes, append modifier -25 to 99205 when a significant, separately identifiable problem-focused E and M service is performed with a preventive visit. The problem-focused component must be documented separately from the preventive exam and must support high MDM independently.
What Is the Medicare Rate for 99205 in 2026?
Medicare reimbursement is approximately $210-260 depending on geographic location. Commercial payer rates range from $200-350. With G2211 add-on code, expect an additional ~$15-20.
Is 99205 a High Audit Risk Code?
Yes. CPT 99205 has one of the highest audit rates among outpatient E and M codes due to its high reimbursement and frequent upcoding errors. Ensure your documentation clearly supports all three MDM elements — problems, data, and risk — at the high complexity level.
Key Takeaways
- Code Purpose: Level 5 new patient visit with high-complexity MDM

- Reimbursement: Medicare ~$210-260; Commercial ~$200-350
- Audit Risk: High — ensure complete documentation supports high MDM
- Common Error: Upcoding 99204 to 99205 without all three data elements or without documented threat to life/function
