HCPCS Code G8918: Patient Without Preoperative Order for IV Antibiotic Surgical Site Infection (SSI) Prophylaxis

Learn about the HCPCS Code G8918 for a patient without a preoperative order for IV antibiotic surgical site infection (SSI) prophylaxis.

Use Code

## **What is the HCPCS code G8918 for?** The HCPCS code G8918 is a non-billable code that designates an instance where a patient who is currently undergoing surgery doesn't have a preoperative order for IV antibiotics. IV antibiotics are used to prevent infections from developing in surgical sites. You'd want to use this code if you notice that a patient's medical records for surgery don't have an order for preoperative IV antibiotics. The lack of such an order could result in a surgical site infection. Knowing if the patient doesn't have this order is essential to surgical teams because they can evaluate the surgical procedure and outcomes. This information can help them determine alternative infection control measures to take to cover for the lack of IV antibiotics. Surgical site infections might lead to acute postprocedural pain/postoperative pain or even chronic pain and other unwanted complications. As mentioned earlier, you can't really bill for this code because it doesn't represent treatment or service, so it doesn't have a payment value that can be filed for a claim. It's more for compliance and transparency.

## **Documentation requirements for G8918** While this isn't a code for a specific type of service, documentation is still important for G8918. For this code, you need to document the following: - A clear note of the absence of a preoperative IV antibiotic order, especially if there is a clinician rationale behind it (e.g., the patient has an allergy to the antibiotic, or if there is an alternative prophylaxis that the surgery team will use). The note must explicitly reflect clear, measured decision-making and intent. - Patient risk assessment - Procedure description - Surgeon's acknowledgment All of these documents need to be retrievable. There cannot be inadvertent omissions. For quality reporting standards and compliance, there must be explicit clinician documentation explaining why IV antibiotics weren't ordered.

## **Billing requirements for G8918** To reiterate, G8918 is unbillable and can't be reimbursed because it's an HCPCS code meant for quality reporting. It should come with the indicator code 00, which means non-payable. G8918 should still accompany a claim when applicable, even if it doesn't affect payment amounts. Absence of this code could result in non-compliance and audit issues. ### **Important note** Please do not confuse HCPCS code G8918 with the ICD-10-CM code G89.18, a diagnosis code that represents other acute postprocedural pain. This is only used if the patient is dealing with pain disorders exclusively related to surgery, but the type of acute postprocedural pain doesn't have a specific ICD code (e.g., pain postpartum after cesarean section, postherniorrhaphy pain syndrome, etc.). Remember that it's for other acute postprocedural pain, not generalized pain (NOS). It's easy to confuse G8918 with G89.18 if you don't type the period in between 9 and 1 when searching for either one, so please be mindful.

Frequently asked questions

Not necessarily. It can still proceed because there could be a reason why antibiotics weren't ordered. Surgical teams will likely have backup plans and other forms of prophylaxis they can use.

Yes. Surgery is always risky, even more so without antibiotics. But some patients might be allergic to IV antibiotics. That's why it's important to understand why they weren't ordered. Knowing the reason why, surgical teams can make adjustments to their procedure.

They will feel localized pain (e.g., pelvic and perineal pain, lumbar region pain, throat pain, spine pain, chest pain, breast pain, limb pain, abdomen pain, ear pain, shoulder pain, joint pain, tooth pain, tongue pain. Pain is just a common problem they will experience. Worse problems include cellulitis, development of abscesses, osteomyelitis, and sepsis. This type of infection needs to be addressed as soon as possible.
