## **What is HCPCS code C1889?**
HCPCS code C1889 (implantable/insertable device, not otherwise classified) is used on hospital outpatient claims when a required implanted or inserted device does not have a more specific HCPCS device code. It is typically reported on the same claim and date of service as a device-intensive procedure to satisfy Outpatient Code Editor (OCE) device-edit requirements. Because C1889 is assigned OPPS status indicator N, its charges are packaged into the payment for the procedure’s APC and it does not receive separate reimbursement.
Hospitals should use C1889 only when documentation supports that a device was implanted or inserted and no more specific device code exists. If the procedure is device-intensive but no device was furnished, C1889 should not be reported. In some ASC settings, other codes such as C1890 may be reported to indicate that no device was provided. Hospitals should verify through their MAC’s device–procedure crosswalk that C1889 is the correct code before submission.
Documentation for C1889 should clearly describe the device used, including its name or brand, and when available, the manufacturer, model or lot number, serial number, and implant site. It must also include the date of service, details of the procedure performed, and a statement of medical necessity. This documentation ensures that the reported code aligns with the device-intensive procedure and supports compliance with Medicare’s billing requirements.
## **HCPCS code C1889 documentation requirements**
When reporting HCPCS Code C1889, providers must ensure the documentation supports the medical necessity and proper use of the device.
- The date of service for when the device was implanted or inserted.
- A clear description of the implantable insertable device not otherwise classified is being reported.
- Details of the procedure performed, including why the device was medically necessary.
- Supporting clinical notes confirming that the service aligns with the HCPCS code C1889 definition.
- Destination or location where the procedure took place, such as a hospital or outpatient setting.
- Documentation must support that the device is FDA authorized or exempt and is an integral part of the service performed, used for one patient only, contacts human tissue, and is surgically implanted or inserted either permanently or temporarily.
## **HCPCS code C1889 billing requirements**
For correct reimbursement, claims using HCPCS Code C1889 must meet the following billing standards.
- Use HCPCS code C1889 only when a more specific HCPCS device code does not describe a device used in the procedure.
- C1889 is reported along with the related device-intensive procedure on the same claim and the same date of service.
- Claims should link the device to the associated procedure and comply with payer-specific guidelines for device-intensive procedures.
- Hospitals primarily use this code; physician billing usually relies on different CPT codes related to the procedure rather than C1889.
- C1889 must not be used if a more specific HCPCS code exists for the device.
- Failure to report the device code with the procedure on the same claim may result in claim denial or return.
