frequently asked questions

What is the Medicare 2-Midnight Stay Rule?

Based on the Medicare 2-Midnight Stay Rule, there is a requirement that hospital inpatient stays must be greater than or equal to 2 midnight stays in order to be eligible for Medicare inpatient reimbursement. A physician order to admit the patient is required, based on clinical necessity and documentation.  If the patient stays less than two midnights and is discharged same day or next day, in most cases, this is considered a hospital outpatient stay

Does an Inari Mechanical Thrombectomy procedure have a HCPCS (Level II) or C-Code?

Inari utilizes established Coding (CPT, ICD-10 PCS, ICD-10 CM) for our arterial and venous mechanical thrombectomy procedures.

An Inari FlowTriever® or ClotTriever® procedure is typically performed as a hospital inpatient procedure and reporting of a HCPCS or C-Code for billing purposes is not required, as is typical with “outpatient” services. Device reimbursement is included as part of the DRG payment.

If an Inari procedure is performed as an outpatient procedure, C1757 (thrombectomy catheter) and C1894 (sheath) can be used to account for the device, in addition to the respective CPT Code for the thrombectomy procedure (i.e.: CPT Code 37184/37185 for an arterial mechanical thrombectomy or CPT Code 37187 for a venous mechanical thrombectomy). However, there is no additional payment for C1757 and C1894, as they are included within the overall Medicare Comprehensive APC payment for the thrombectomy procedure.

As for entering FlowTriever into the chargemaster, we have seen facilities create a “FT-PPP” (FlowTriever Price Per Procedure) charge for the cost of the FlowTriever, whether you use one component of the FlowTriever or multiple components of the FlowTriever.

Does my provider need to state “Extirpation of Matter” when dictating for the Inari Mechanical Thrombectomy procedures?

The definition for the root operation Extirpation is “taking or cutting out solid matter from a body part.”  

While it is not necessary for a physician to say the term “extirpation” when describing a thrombectomy, it accurately describes the root operation for the inpatient procedure performed.  Hospital inpatient coders use the definition of the root operation as well as the dictation and procedure documentation to determine that a thrombectomy is a type of extirpation, and that you are “removing” or “taking out” clot or thrombus from the respective body part.

Which CPT Code should I utilize when coding for a Clot in Transit (CIT) in the Right Atrium using FlowTriever®?

The current guidance is to utilize the unlisted CPT® Code 33999 (unlisted procedure, cardiac surgery) when coding for the Physician Professional Services.  When submitting an unlisted procedure code, a concise description of the procedure must be included in Item 19 of the CMS-1500 paper form or the electronic media claim (EMC) form. Choose a comparison code that is similar to the unlisted procedure performed. This code should represent surgery on the same body area.  A copy of the operative report should be submitted, along with supporting information outlining the decision-making process and the medical rationale for performing the procedure.

There is established ICD-10 PCS Procedure Coding for extirpation of matter from the right atrium, along with associated MS-DRG assignment, for the hospital.

Which HCPCS or CPT code should I utilize for the FlowStasis® Suture Retention Device?

For most vascular procedures, physician & facility payment for closure devices are packaged into the primary procedure performed (i.e.:  no separate, line-item payment).  To capture cost resource utilization during a procedure (especially outpatient), this Level II HCPCS code may be used for FlowStasis:

 

  • G0269 = Placement of occlusive device into either a venous or arterial access site, post-surgical or interventional procedure (e.g., Angioseal plug, vascular plug).
