## **What is the HCPCS code L8699 for?**
The HCPCS code L8699 is an HCPCS code for prosthetics. It is meant to designate the provision of a prosthetic implant, not otherwise specified. It falls under Miscellaneous Orthotic and Prosthetic Services and Supplies.
What does "not otherwise specified" mean? This means that the prosthetic implant, whether it's a joint implant, spinal hardware, bone void filler, or other custom or uncommon implant, doesn't have a dedicated code for prosthetic implant.
This code covers the surgical insertion of the implant during operative procedures. These procedures are orthopedic, neurosurgical, or reconstructive.
This is a catch-all HCPCS code to ensure appropriate reimbursements and tracking when no exact descriptors/codes exist for the implant being inserted.
## **Documentation requirements for L8699**
As with any HCPCS code, you need to have sufficient documentation before filing a claim for this code. Here are some of what you need:
- The full name of the patient
- The full name and credentials of the healthcare professional who inserted the implant
- The patient's medical history, any relevant diagnoses, and test results to justify the medical necessity for using this implant
- The specifics of the implant and the documentation of its purposes, goals, and benefits, like pain management, addressing a patient with benign prostatic hyperplasia (BPH)
- Detailed operative report specifying the type of implant, surgical site, and clinical rationale for the implant
## **Billing requirements for L8699**
Besides the documentation requirements above, please take note of or have the following:
- Clear notation that no more specific HCPCS code applies
- Any related ICD codes to accurately describe the patient's condition
- If applicable, side designation via modifiers RT (right side) or LT (left) for unilateral implants—bilateral implants generally require only one modifier and may limit reimbursement to one side
- Any appropriate CPT codes
- For ASCs, report acquisition cost (AC) based on invoice; L8699 may require prior authorization when no specific code exists
- Date of service of the implant insertion must be the same as whatever primary procedure the patient underwent (e.g., urolift system to treat BPH)
Please make sure you follow the correct CMS/Medicare/related guidelines and policy articles to ensure you follow correct coding procedures and avoid claim rejections.
One related article you might want to familiarize yourself with is the ASC payment policy. Someone inquired via the AAPC website for HCPCS codes about receiving payment for implants L8699 or bone grafts (C1762) billed in an ASC, and they mentioned they were denied and didn't get reimbursed for allograft. You don't want this to happen to you, so please read up on the necessary policies.
