Complete and accurate procedure code, modifier and diagnosis code usage at the time of billing ensures accurate processing of correct coding initiative edits. Wecan only use the primary modifier submitted with the alternate procedure code for outpatient billing. We encourage you to purchase current copies of CPT, HCPCS and ICD code books.
The correct coding initiative edits and medically unlikely edits will apply to outpatient claims from the following hospitals and facilities:
• Acute care hospitals
• Long term acute care hospitals
• Ambulatory surgical centers
• Psychiatric facilities
• Substance abuse facilities
• Inpatient rehabilitation facilities
• Skilled nursing facilities
Note: Ambulatory surgical centers will follow institutional correct coding initiative edits forour commercial business, while our Medicare Advantage business will process against the professional edits.
A modifier allows a provider to indicate that a service or procedure is altered by some specific circumstance, but the definition or code is not changed. Modifiers may be used in some instances when additional information is needed for proper payment of claims. Valid modifiers and their descriptions are found in the most current CPT and HCPCS coding books.
Weprocess claims using only the first modifier for outpatient institutional claims. While up to three modifiers are accepted, claims are processed using only the first modifier. Therefore, submit the most important modifier affecting reimbursement in the first position on paper and electronic claims.
Note: If your claim is denied due to a lack of documentation to support the use of a specific modifier, you may submit an appeal. Your appeal must be submitted in writing and accompanied by the necessary documentation. 4
Modifiers may be used to indicate that:
• A service or procedure has been increased or reduced
• Only part of a service was performed
• A bilateral procedure was performed
• A service or procedure was provided more than once
