Is Your Practice Audit-Ready? Why CPT® 90833 Is Under Increased Scrutiny

Behavioral health providers rely on CPT® 90833 to accurately report psychotherapy performed during medication management visits. When documented correctly, this add-on code appropriately reflects the additional clinical work performed. However, because 90833 directly affects reimbursement, it has become one of the most closely reviewed behavioral health billing codes by commercial payers and government auditors. (-)

For psychiatric practices, documentation deficiencies can result in denied claims, repayment demands, or even payer audits. The good news is that most audit findings are preventable with consistent documentation and internal quality reviews.

What Is CPT® 90833?

CPT® 90833 is an add-on psychotherapy code used when psychotherapy is provided during the same encounter as an Evaluation and Management (E/M) service.

Key requirements include:

• Must be billed with an eligible E/M service

• Represents 16–37 minutes of psychotherapy

• Psychotherapy must be medically necessary

• Documentation must clearly distinguish psychotherapy from medication management services (TheraFocus)

Simply discussing medications, reviewing symptoms, or providing brief education does not automatically support billing 90833.

Common Audit Findings

1. No Separate Psychotherapy Documentation

One of the most frequent audit findings is documentation that blends psychotherapy into the E/M note without clearly identifying the therapeutic service.

Auditors expect documentation describing:

• Therapeutic interventions performed

• Patient response

• Treatment goals

• Progress toward those goals

General statements such as "supportive counseling provided" rarely support the service. (Think Beyond Practice)

2. Missing Psychotherapy Time

90833 is a time-based code.

Documentation should clearly support that psychotherapy lasted between 16 and 37 minutes. Many organizations document either:

• Total psychotherapy minutes, or

• Psychotherapy start and stop times (depending on payer preference)

Practices should understand payer-specific documentation expectations. (Debbie Granick)

3. Medication Management Only

Medication adjustments alone do not justify 90833.

Examples of E/M activities include:

• Medication changes

• Side effect review

• Laboratory review

• Medical decision making

• Risk assessment

Psychotherapy must include therapeutic techniques such as:

• Cognitive Behavioral Therapy (CBT)

• Supportive therapy

• Motivational interviewing

• Behavioral activation

• Interpersonal therapy

• Problem-solving therapy

These services must be documented separately from medical management. (-)

4. Identical Documentation Across Visits

Auditors often identify copy-and-paste documentation patterns.

Repeated language that appears identical across multiple encounters may suggest psychotherapy was not individualized.

Each encounter should reflect:

• Current patient concerns

• Therapeutic interventions used

• Patient response

• Updated treatment goals

Internal Audit Checklist

Practices should routinely review 90833 documentation to confirm each encounter includes:

✅ Qualifying E/M service

✅ Medical necessity

✅ Psychotherapy time documented

✅ Distinct psychotherapy note

✅ Therapeutic modality identified

✅ Patient response documented

✅ Treatment goals addressed

✅ Individualized documentation

Best Practices to Reduce Audit Risk

Successful behavioral health organizations often implement standardized documentation workflows that include:

• Provider education

• Documentation templates

• Quarterly internal chart audits

• Coding compliance reviews

• Regular payer policy monitoring

• Clinical documentation improvement initiatives

Routine audits help identify documentation trends before they become payer concerns.
