What Is CPT Code 99215 and Why It Matters for Your Practice
CPT code 99215 represents the highest level of evaluation and management (E/M) service for established patient office or outpatient visits. For mental health providers, particularly psychiatrists, understanding when and how to appropriately use this code is crucial for accurate reimbursement and compliance with current medical coding standards.
Since the significant E/M coding changes implemented in January 2021 as per American Medical Association (AMA), billing for 99215 has become more straightforward, focusing on either medical decision-making (MDM) complexity or total time spent on the date of encounter. This guide provides accurate, up-to-date information to help mental health professionals navigate 99215 billing confidently.
Current Requirements for Billing CPT Code 99215
To bill CPT code 99215 appropriately, your encounter must meet one of two criteria:
Option 1: Time-Based Billing
- Minimum 40 minutes of total provider time on the date of encounter
- Time includes both face-to-face and non-face-to-face activities
Option 2: Medical Decision-Making (MDM)
- High complexity medical decision-making
- Requires meeting 2 of 3 MDM elements at the high level
Important note: Unlike pre-2021 guidelines, comprehensive history and physical examination are no longer required elements for code selection. Providers should document only medically appropriate and clinically relevant history and exam findings.
Understanding High-Complexity Medical Decision-Making
High-complexity MDM requires meeting at least two of these three elements:
1. Number and Complexity of Problems Addressed
High level requires one or more of:
- One or more chronic illnesses with severe exacerbation, progression, or side effects
- One acute or chronic illness posing threat to life or bodily function
- Multiple stable chronic conditions requiring extensive management
Mental health example: A patient with treatment-resistant major depression experiencing severe exacerbation with emerging psychotic features, requiring immediate medication adjustment and safety planning.
2. Amount and/or Complexity of Data Reviewed
High level requires meeting at least one category combination:
- Review of prior external notes from unique sources (3 sources)
- Ordering or reviewing 3+ unique tests
- Assessment requiring independent historian
- Independent interpretation of tests
- Discussion of management with external physician/qualified healthcare professional
Mental health example: Reviewing records from previous psychiatrist, recent emergency department visit, and primary care provider; ordering metabolic panel and thyroid studies; discussing care coordination with patient's therapist.
3. Risk of Complications and/or Morbidity or Mortality
High level includes:
- Drug therapy requiring intensive monitoring for toxicity
- Decision regarding emergency hospitalization
- Decision for elective major surgery with identified risk factors
- Decision not to resuscitate or to de-escalate care
Mental health example: Initiating clozapine requiring frequent blood monitoring, managing lithium toxicity, or determining need for psychiatric hospitalization.
Time-Based Billing: What Activities Count?
When billing based on time, include all provider activities on the encounter date:
Pre-visit activities:
- Reviewing patient charts and previous records
- Reviewing lab results or psychological testing
- Preparing for the visit
During the visit:
- Face-to-face time with patient and/or family
- Counseling and education
- Performing examination
Post-visit activities:
- Documenting the medical record
- Communicating with other healthcare providers
- Ordering medications, tests, or procedures
- Reviewing and interpreting results
- Care coordination
Critical point: Only count time personally spent by the billing provider, not time spent by clinical staff.
Special Considerations for Mental Health Providers
Psychiatrists and E/M Codes
Psychiatrists billing under the medical model can use 99215 for medication management and evaluation visits. When providing psychotherapy during the same encounter, use the appropriate add-on codes:
- 90833: 16-37 minutes of psychotherapy with E/M
- 90836: 38-52 minutes of psychotherapy with E/M
- 90838: 53+ minutes of psychotherapy with E/M
If you are billing add-on psychotherapy, you must bill the original 99215 code according to E/M not time.
Documentation Example for 99215
Chief Complaint: "Worsening depression despite medication"
HPI: 45-year-old with treatment-resistant MDD, GAD, and PTSD presenting with severe depressive episode. Reports significant worsening over past 2 weeks with emergence of passive suicidal ideation, severe insomnia, and 10-pound weight loss. Currently on sertraline 200mg and bupropion 300mg with partial response.
MDM Documentation:
- Problems: Severe MDD exacerbation with SI (high complexity)
- Data: Reviewed recent PCP labs, consulted with therapist, reviewed PHQ-9 trends (high complexity)
- Risk: Adjusting to TCA requiring EKG monitoring, considering hospitalization (high risk)
Time: 45 minutes total (35 minutes face-to-face, 10 minutes coordination/documentation)
Prolonged Services: 99417 vs. G2212
If your total same-day time substantially exceeds the 99215 threshold, consider prolonged-service reporting:
- Commercial payers often recognize CPT +99417 (each additional 15 minutes beyond 99215’s time).
- Medicare uses HCPCS G2212 instead. CMS policy differs from the AMA’s; for Medicare you append G2212 when the visit exceeds the time for the highest level by at least 15 minutes (check your MAC’s threshold table for the exact minute counts).
The New Visit-Complexity Add-On: G2211 (Medicare)
Use G2211 with office/outpatient E/M codes 99202–99205, 99211–99215 when the visit reflects the inherent complexity of a longitudinal care relationship—either you serve as the patient’s continuing focal point for all needed care, or you’re providing ongoing care for a single, serious or complex condition. It’s an add-on to the E/M (same date, same clinician) and is not tied to time or MDM level. CMS doesn’t require extra templates; just make sure your note makes the medical necessity and the ongoing relationship clear (e.g., “I manage this patient’s recurrent, treatment-resistant MDD longitudinally; today’s medication and safety planning decisions are informed by that ongoing relationship”).
Common Appropriate ICD-10 Codes for 99215 Encounters
When billing 99215, use specific ICD-10 codes that reflect the complexity:
- F32.2 - Major depressive disorder, single episode, severe without psychotic features
- F33.3 - Major depressive disorder, recurrent, severe with psychotic symptoms
- F31.4 - Bipolar disorder, current episode severe depression without psychotic features
- F25.0 - Schizoaffective disorder, bipolar type
- F20.9 - Schizophrenia, unspecified
- F43.12 - Post-traumatic stress disorder, chronic
- F60.3 - Borderline personality disorder
2025 Medicare Reimbursement Rates
Current Medicare reimbursement for 99215 varies by geographic location but typically is around $180 per visit nationally (based on CMS Physician Fee Schedule). Commercial insurance often reimburses 20-40% higher than Medicare rates. Always verify current rates with your Medicare Administrative Contractor (MAC) and commercial payers.
When to Use 99214 vs 99215
Use 99214 (moderate complexity) when:
- Managing stable chronic conditions with routine adjustments
- Addressing exacerbation of single condition without significant risk
- Spending 30-39 minutes on encounter date
Use 99215 (high complexity) when:
- Managing multiple unstable conditions
- Addressing severe exacerbation with safety concerns
- Making complex medication changes requiring monitoring
- Spending 40+ minutes on encounter date
Best Practices for Compliance and Optimization
Documentation Tips
- Be specific: Document exact time spent and activities performed
- Support complexity: Clearly describe factors making the visit high-complexity
- Use templates wisely: Ensure documentation is individualized and accurate
