Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Psychiatric diagnostic evaluation (90791 or 90792) may be reported once at the onset of treatment; a diagnostic evaluation may be repeated only after an extended break in treatment defined as at least six months from the last time the patient was seen or treated for their psychiatric condition.

90791 and 90792: May be reported with +90785; Not to be reported with 90839 or +90840.

Timed psychotherapy codes (90832, 90834, 90837) require minimum service minutes (90832 >=16 minutes; 90834 >=38 minutes; 90837 >=53 minutes).

90832, 90834, 90837: May be reported with +90785. Not to be reported with +90833, +90836, +90838, 90839, +90840, 90846 (except when separate and distinct as noted), or 90847 (except when separate and distinct).

Psychotherapy with separately identifiable E/M add-on codes (+90833, +90836, +90838) must be reported with the appropriate E/M as primary (codes first: 99202-99239, 99304-99316, 99341-99350) and are not reportable with standard psychotherapy codes (90832/90834/90837), crisis codes (90839/+90840), or specified family codes (90846/90847).

Pharmacologic management add-on (+90863) is reported in addition to psychotherapy (code first 90832/90834/90837) and is not to be reported with 90839 or +90840. For other providers, use appropriate E/M codes for medication management as applicable.

Interactive complexity (+90785) is an add-on code for communication complications; it is not a standalone service, not intended to report increased time, not for translation/interpretation, and has specific reporting constraints (may be reported with 90791, 90792, 90832, +90833, 90834, +90836, 90837, +90838, 90853; not to be reported with 0362T, 0373T, 90839/+90840, 90847, select assessment codes, 90846, 97151, etc.).

Crisis psychotherapy (90839) is reported for the first 30–74 minutes and may be reported only once per day; +90840 reports each additional 30-minute increment beyond 74 minutes. 90839/+90840 may be reported together (code first 90839) and are not reportable with +90785, 90791, 90792, 90832, +90833, 90834, +90836, 90837, +90838.

Family and group therapy codes (90846, 90847, 90853): 90847 has a minimum service time (>=26 minutes). 90846 and family/group therapy may be reported with 90839/+90840 when allowed; 90853 may be reported with +90785. Each family/group code includes its own not-to-be-reported-with constraints as specified.

General billing and governance rules: Providers must submit claims using valid HIPAA-approved code sets and follow industry coding guidelines; the Plan reserves the right to request supporting documentation, claims are subject to code edit protocols and review, and plan documents or provider contracts govern in conflicts.

Documentation, Claim Review, and Governing Documents

Documentation Required

Documentation requests — The Plan may request supporting documentation

Providers are responsible for submission of accurate documentation of services performed. The Plan reserves the right to request supporting documentation; providers should submit documentation upon request. Failure to adhere to coding and billing policies may impact claims processing and reimbursement.

Submit accurate, complete medical records and coding documentation upon request.
Failure to provide requested documentation may result in claim denial or adjusted reimbursement.

Note

Claim review and governing documents — Claims are subject to plan, contract, medical policy, and coding software review

Claims are subject to review against plan documents, provider contracts, medical policies, clinical payment and coding policies, and coding-software logic. If a conflict exists between this Clinical Payment and Coding Policy and a member's plan document, the plan document governs. If a conflict exists between this policy and a provider contract, the provider contract governs. Blue Cross and Blue Shield of Illinois (BCBSIL) may apply reasonable discretion in interpreting and applying this policy; BCBSIL has full and final discretionary authority to the extent permitted by applicable plan documents.

Claims must be coded per HIPAA-approved code sets and industry-standard guidelines (CPT, HCPCS, ICD-10-CM/PCS, NDCs, DRG, CMS and NCCI guidance).
Claims are subject to code edit protocols and claim review; plan documents or provider contracts govern in case of conflicts.

LimitationsNot to be reported for translation/interpretation, not to be reported with certain codes (e.g., 90839, +90840, 90847, 90846 as listed), and time alone does not justify reporting +90785
