Understanding Billable vs Non-Billable Codes

ICD-10-CM codes are classified as either billable/specific or non-billable/non-specific. Billable codes can be used on insurance claims for reimbursement. Non-billable codes are typically parent or header codes that require a more specific sub-code for actual billing.

When a code is non-billable, always look for its child codes (sub-codes) which provide the necessary specificity for reimbursement. Using a non-billable code on a claim may result in denial or delayed payment.

About Billable Status

Billable status indicates whether a code can be used for reimbursement purposes. Non-billable codes are typically header or parent codes that require a more specific sub-code for actual billing and claims. Always verify with the latest payer guidelines.
