CPT Code 90839 Description & Reimbursement Guidelines

Accurate billing is a cornerstone of mental health services, ensuring that providers are

fairly compensated for the care they provide. However, many practices face frequent claim denials. The reason? Incorrect medical coding and billing. There are hundreds of CPT codes related to mental health, which makes billing a complex task. Moreover, the continuously changing billing guidelines and standards make it even more challenging. 

One of the most frequently used codes in mental health billing is CPT code 90839. It is an important crisis intervention code and requires attention to detail. That is why our billing experts at NeuraBill have compiled this comprehensive guide. 

In this guide on CPT code 90839, we will discuss the code’s description, applicable scenarios, modifiers, and billing and reimbursement guidelines. So, let’s start.  

CPT Code 90839 Description

CPT Code 90839 is a billing code designed for mental health professionals to document

and bill for psychotherapy services provided during a crisis. Specifically, it covers the first

60 minutes of a crisis intervention session. The official definition is:

“Psychotherapy for the crisis, first 60 minutes.”

This code is mostly used to provide immediate, focused therapy to a patient experiencing an acute mental health emergency, for example, in situations where a patient is having suicidal thoughts or overwhelming anxiety. 

CPT code 90839 falls within the Psychiatry section of the CPT manual. An important thing that many billers overlook is that, unlike standard psychotherapy codes (such as 90832, 90834, or 90837), CPT 90839 is specifically designated for crisis situations that demand urgent assessment. 

Key components of CPT code 90839 are:

• Urgent assessment and history of the crisis state
• Mental status examination to evaluate the patient’s current psychological condition
• Psychotherapeutic intervention to address the immediate crisis
• Mobilization of resources to defuse the crisis and restore safety
• Implementation of interventions to minimize potential psychological trauma
• Formulation of a disposition plan for follow-up care

Remember that a crisis is characterized by:

• High level of distress
• Potential danger to self or others
• Need for immediate intervention
• Complex circumstances requiring urgent attention
• Inability to wait for standard appointment scheduling

When these criteria are met, CPT code 90839 is the appropriate billing code for the services

provided.
