Provider Eligibility

Choosing the Correct Code
To ensure proper billing and compliance, choosing the right code is a necessity. Providers have to assess the type of service rendered to decide if any medical services were included. Incorrect coding may lead to denied claims and is a high risk to be audited.
Common Billing Errors and How to Avoid Them
Duplicate Billing
One common billing error is billing CPT 90791 multiple times for the same patient and not having enough clinical evidence to support the claims. Providers should make sure there is clear evidence justifying support for the clinical need of a repeat evaluation.
Incorrect Code Selection
Another issue is the misuse of CPT 90791 when medical services are in fact rendered. In that case, CPT 90792 needs to be used. Confirming the particulars of the service performed before billing the claim will help minimize this error.
Lack of Medical Necessity
Claim documentation that fails to demonstrate a thorough medical necessity may lead to denial of payment. Providers must integrate the evaluation of the patient’s symptoms with the need for clinical evaluation.
Incomplete Documentation
When documentation is absent, deficiencies may lead to claim denial and auditing. Providers need to ensure that all of the components are reflected and that the documentation to the services delivered is complete.
Compliance and Best Practices
Payer Guidelines
In order for billing to be successful, compliance with the distinct guidelines of each payer is essential. Each health insurance company has individual documentation, coverage, and service frequency requirements. Knowledge of these guidelines increases the chances of correct billing and payment.
Use Accurate Coding Practices
From a financial and compliance point of view, coding is extremely important. Providers should be using the correct coding for the service delivered and ensure that up to date coding is being utilized.
Maintain Clear and Detailed Records
Good billing and patient care are the results of good record keeping. Thorough documentation is necessary to guarantee the next care giver to treat that patient knows what has transpired.
Stay Updated with Regulatory Changes
Changes are made to the reimbursement and health care rules and standards regularly. Providers must keep up with these changes in order to remain compliant and avoid the consequences of non-compliance.
