In behavioral health, every therapy session is valuable—but in billing, value is also measured in minutes. From the first words exchanged to the last therapeutic insight, session time plays a central role not just in treatment but in reimbursement. Time-based CPT codes form the foundation of converting therapeutic care into accurate billing.
Whether you're delivering a standard 30-minute session or handling a time-sensitive crisis intervention, selecting the right CPT code ensures your services are properly captured and reimbursed. This blog dives into how these codes work and why precise timing is critical in offshore medical billing and coding services in India.
The Importance of Time in Behavioral Health Billing
Time-based CPT codes are essential tools that align billing with the actual duration of psychotherapy sessions. These codes—like 90832, 90834, and 90837—allow licensed professionals such as psychologists, psychiatrists, social workers, and nurses to reflect their service time accurately in billing documentation.
For example, 90837, used for 60-minute sessions, is among the most frequently billed codes in the U.S., showing a clear preference for extended, in-depth therapy. If session times aren't correctly recorded or an inappropriate CPT code is chosen, it can lead to claim denials or payer audits. That’s why providers must document exact start and end times and stay up to date with the latest offshore behavioral health billing and coding services rules to ensure compliance and prevent revenue leakage.

Tips for Accurate Time-Based Billing
Getting time-based coding right means fewer denials and smoother claim processing. Here are essential strategies for staying accurate and compliant:
● Log Exact Session Times
Always document the specific start and end times of each therapy session. This detail is critical during audits and ensures that billing accurately reflects the care provided.
● Match Codes to the Correct Time Intervals
Refer to updated guidelines to ensure code accuracy:
- 90832: 16–37 minutes
- 90834: 38–52 minutes
- 90837: 53+ minutes
Incorrect coding can trigger rejections or underpayment.
● Use Modifiers for Telehealth
Attach Modifier 95 to all virtual sessions and confirm you're using the correct Place of Service (POS) code, such as POS 10 or POS 02, depending on payer requirements.
● Don’t Bill for Sessions Under 16 Minutes
Most payers do not consider sessions under 16 minutes to be billable. Submitting these could lead to compliance issues.
● Apply Add-On Codes When Needed
For crisis services extending beyond 60 minutes, be sure to bill 90840 alongside 90839. This ensures you're accurately reimbursed for prolonged care.
