ICD-10 codes are diagnostic codes used for documentation and billing insurance payers. Once you diagnose a patient and begin their treatment plan, you’ll choose the corresponding ICD-10 code and include it in your documentation and insurance claim. As with all documentation, accuracy with ICD-10 codes is important for compliance purposes — and ensuring you get paid for your work in a timely manner.

The process of navigating payer requirements and billing insurance can feel cumbersome, but it doesn’t have to be. Headway streamlines the process, making it easy for you to submit accurate and compliant claims, every time. Below, find the most common ICD-10 codes used by psychiatrists — and how Headway can support your documentation and billing processes.

Documenting ICD codes for psychiatry

Documentation is a critical aspect of compliance for any mental health provider, including psychiatrists. Your chosen ICD code reflects your patient’s diagnosis, ultimately supporting the treatment plan you’re billing for. In order to get paid in a timely way, always choose the most accurate ICD code for your psychiatry session notes and billing documents.

Using a notes template, such as SOAP notes, can help ensure you include all pertinent details from a patient session while supporting compliance to insurance payers’ requirements. These requirements can be complex to navigate, even for the most experienced providers. Headway’s documentation tools and templates support your clinical and administrative workflows by making it easy to write compliant notes and submit accurate claims the first time.
