Delivering quality care goes hand-in-hand with thorough and compliant documentation in the field of behavioral health. But in Washington state—where Medicaid reforms, increased audits, and a growing emphasis on fraud prevention are shaping the billing landscape—behavioral health providers must pay extra attention to their documentation and billing practices.

Even the smallest of charting errors can raise red flags, delay reimbursement, or worse—trigger audits and legal scrutiny.

DO: Document Medical Necessity Clearly

Every service billed must be clinically justified. In Washington, Medicaid and commercial payers are increasingly scrutinizing whether behavioral health sessions meet medical necessity requirements.

Best Practice: Use language that links symptoms to diagnoses, outlines functional impairments, and explains how your services address specific treatment goals. Avoid vague notes like “client is doing well” without context. Instead, write: "Client reports persistent depressive symptoms interfering with work; CBT session focused on reframing cognitive distortions."

DON’T: Use Copy-Paste Progress Notes

Templated notes or copy-pasting from previous sessions may seem efficient—but they’re a fast track to compliance issues. Payers and auditors look for individualized care, and repeated phrasing can be seen as evidence of fraud.

• Avoid : Repeating the same interventions or client responses verbatim across multiple dates.
• Instead : Even if treatment goals remain consistent, tailor each note to the session’s unique content and client progress.

DO: Be Precise with Time and CPT Codes

Billing the wrong CPT code—or billing for more time than actually spent—can land your practice in hot water. Washington payers are especially sensitive to time-based discrepancies.

Best Practice : Document actual session duration and match it to the corresponding CPT code. Include start and stop times in the note, and ensure the documented interventions support the code billed.

DON’T: Bill for Missed Appointments or Incomplete Services

While it may be tempting to recoup lost revenue, billing for no-shows or sessions that ended early due to client issues is a major red flag.

Policy Tip : Washington Medicaid does not allow billing for missed appointments. Ensure your EHR and billing systems prevent claims submission for such events.

DO: Maintain Up-to-Date Treatment Plans

Outdated or boilerplate treatment plans suggest poor clinical oversight and can undermine your entire documentation trail.

Best Practice: Review and update treatment plans at regular intervals, especially when symptoms change, goals are met, or new diagnoses are introduced. Each update should reflect measurable objectives and current interventions.
