BCBS-TN Psychiatry Billing Policies

CCI Edits & Code Bundling

NCCI (National Correct Coding Initiative) edits and CMS bundling logic are strictly enforced. Component codes billed on the same day by the same provider (e.g., diagnostic and psychotherapy codes, or E/M and psychotherapy) are often denied unless proper add-on codes or modifiers are used .
Quarterly updates: BCBS-TN releases quarterly "Code Bundling Rationale" updates. Review these regularly via the provider portal to stay current .

CPT Code-Specific Billing Rules

90791 – Psychiatric Diagnostic Evaluation

Intake only: Use for new patient evaluations or reassessment after a gap. Do not bill with psychotherapy codes (90832, 90834, 90837) or E/M codes (99213, 99214) on the same day, same provider—these combinations will trigger CCI denials .
Documentation: Clearly document the diagnostic focus. If the session is primarily therapeutic, use the appropriate psychotherapy code.

90834 & 90837 – Psychotherapy (Timed)

90834: 38–52 minutes (approx. 45 min session)
90837: ≥53 minutes (60 min session)
Do not bill standalone psychotherapy codes with E/M codes on the same day by the same provider. If both are performed, use add-on codes (90836 for 45 min, 90838 for 60 min) with E/M .
Do not bill psychotherapy codes with 90791 on the same day, same provider .
Documentation: Record start/stop times and clinical justification, especially for 90837, which is flagged for overutilization.

99213 & 99214 – E/M (Established Patient)

Billable for established patient visits. If psychotherapy is also provided, use add-on codes (90833, 90836, 90838) as appropriate .
Modifier 25: Use when E/M is a significant, separately identifiable service alongside a minor procedure.
Bundling: E/M codes are bundled with minor procedures unless modifier 25 is applied.

Submission Requirements & Documentation

Provider Administration Manual (PAM): The Commercial PAM is your definitive reference for billing procedures, bundling rules, and reimbursement policy .
Behavioral Health section: Contains guidance specific to your codes.
Eligibility checks: Always verify benefit limits and frequency caps before scheduling high-frequency or extended sessions.

Actionable Workflow Recommendations

Pre-claim edits: Implement workflow checks to block prohibited same-day combinations (e.g., 90791 + psychotherapy, E/M + psychotherapy without add-ons).
Quarterly review: Set reminders to review BCBS-TN’s quarterly code edit updates.
Documentation rigor: Ensure time, clinical rationale, and service differentiation are clearly documented for every claim.
Modifier use: Apply modifier 25 for E/M when appropriate.

Cigna Psychiatry Billing Policies in Tennessee

Key Billing Policies & Procedures

Use of CPT Codes: Bill using the most appropriate, current CPT codes for the services rendered. Claims with deleted or outdated codes will be denied .
Coverage Policy Alignment: Services must match Cigna’s coverage policies, including medical necessity criteria and covered diagnoses. Services billed for non-covered conditions will be denied .
NCCI/CCI Edits: Cigna applies NCCI edits through its ClaimsXten™ system. Code combinations (like E/M and psychotherapy on the same day) may be bundled or denied unless proper modifiers and documentation are used. Edits are updated annually .
Modifier Requirements: When billing E/M codes (99213, 99214) with psychotherapy (90834, 90837), use modifier 25 to indicate a significant, separately identifiable E/M service. Cigna may request clinical documentation to support modifier use .
Documentation: For combinations triggering edits (e.g., E/M + psychotherapy), documentation must clearly show distinct services, medical necessity, and time spent. Attach notes as needed to support modifier 25 or 59 use.
Time-Based E/M Codes: Cigna recognizes time thresholds for E/M codes:
- 99213: 20–29 minutes
- 99214: 30–39 minutes Documentation should reflect these time ranges when billed with other services .
Psychiatric Diagnostic Evaluation (90791): 90791 is covered when medically necessary, including for autism spectrum disorder evaluation. Coverage depends on meeting clinical criteria .
Claim Submission Standards: Submit claims electronically using CMS-1500 or UB-04 forms. Ensure all required fields are completed, codes are current, and modifiers/documentation are attached as needed. Unlisted codes require detailed reports and invoices .
Plan-Specific Variations: Some Cigna plans (especially self-funded or government-administered) may have unique rules. Always check the member’s plan documents or consult your Cigna rep for exceptions .
