What can happen if treatment or billing is not coded properly?

• A. The insurance company can deny payment.
• B. The claim is automatically approved.
• C. The patient is billed twice.
• D. There is no impact on payment.

Answer: (A)

The essential idea is that coding is the language the payer uses to decide if a service is covered and how much to pay. Each treatment, procedure, and diagnosis must be represented by accurate CPT/ICD-10-CM codes that match what was actually done and why it was done. When coding is not accurate or not supported by the medical record, the claim can be flagged as incorrect, and the insurance company will often deny payment or require correction before reimbursement is released. This safeguards against paying for the wrong services or for services not medically necessary. In practice, this means mismatches—such as billing a higher-level procedure than what documentation supports, using an inappropriate diagnosis code, or omitting necessary codes—can trigger denial, delays, or a need for resubmission with proper documentation. The other options imply automatic approval, no impact on payment, or double billing, which aren’t the typical consequences of improper coding; those outcomes aren’t aligned with how claims are adjudicated.
