Under coding is defined as charging less than what should be charged for a procedure.

• A. Billing for a service at a higher level than provided
• B. Billing for a service twice
• C. Not using ICD-10 codes
• D. Charging less than what should be charged for a procedure

Answer: (D)

Under coding means billing for a procedure at a amount or level of service that is lower than what was actually performed. When a coder assigns a lower-level code or uses a less comprehensive code than the services provided, the reimbursement from the payer is shorter than it should be. The statement that under coding is charging less than what should be charged captures this idea directly. The other situations describe billing more than was provided, billing the same service twice, or omitting the correct diagnosis codes—these are different issues from undercoding. Understanding this helps ensure accurate reimbursement and compliance in medical billing.
