Psychotherapy Documentation & Coding Handbook Second Edition

UPDATED FOR 2026

Your essential reference to confidently code, document, and get paid for the psychotherapy you already deliver.

The Coding Companion for Therapy Documentation and Billing Support was designed for psychiatric nurse practitioners who integrate psychotherapy with medication management—or provide standalone therapy.

Too often, providers under-code their work, leaving revenue on the table or struggling to justify their services. This guide empowers you to confidently integrate therapy into your visits, demonstrate medical necessity, and protect your time and income.

Crystal Stone, PMHNP-BC, FNP-BC, CPMA, CPC, and CPB of New Leaf Billing, Coding, and Auditing Solutions, LLC, conducted an independent content review of this second edition for general alignment with documentation and coding standards.
