Billing Examples
Clinical interactions should consistently connect findings to the overall treatment planning, emphasizing measurable goals. For instance, if a clinician provides therapy to a patient with anxiety using cognitive-behavioral techniques, the documentation should reflect the therapeutic strategies employed, the patient’s engagement and feedback, and how these relate to specific treatment objectives. Documentation should demonstrate clinical necessity for each billed code, providing a clear narrative that supports the services rendered.
Compliance Guidelines
- Verify payer policies regarding coverage and authorization requirements before submitting a claim for reimbursement.
- Documentation must establish medical necessity and appropriately link services to corresponding ICD-10 diagnoses to support billing.
- Ensure the correct application of modifiers, such as modifier 95 for telehealth services, as required by payer guidelines.
- Avoid the practice of upcoding; select codes that accurately represent the documented time and service level provided.
- Conduct regular audits to identify potential denial issues, address documentation gaps, and enhance the quality of clinical records.
