FOR ESSENTIAL TREMOR, PARKINSON S DISEASE, DYSTONIA AND OBSESSIVE- COMPULSIVE DISORDER EFFECTIVE JANUARY 2017 Medtronic provides this information for your convenience only. It does not constitute legal advice or a recommendation regarding clinical practice. Information provided is gathered from third-party sources and is subject to change without notice due to frequently changing laws, rules and regulations. Medtronic makes no guarantee that the use of this information will prevent differences of opinion or disputes with Medicare or other payers as to the correct form of billing or the amount that will be paid to providers of service. Please contact your Medicare contractor, other payers, reimbursement specialists and/or legal counsel for interpretation of coding, coverage and payment policies. This document provides assistance for FDA approved or cleared indications. Where reimbursement is sought for use of a product that may be inconsistent with, or not expressly specified in, the FDA cleared or approved labeling (e.g. instructions for use, operator s manual or package insert), consult with your billing advisors or payers on handling such billing issues. Some payers may have policies that make it inappropriate to submit claims for such items or related service. Because Medtronic DBS Therapy for dystonia and obsessive-compulsive disorder is approved for use under a Humanitarian Device Exemption (HDE), devices can be implanted only in facilities with institutional review board (IRB) approval. The following information is calculated per the footnotes included and does not take into effect Medicare payment reductions resulting from sequestration associated with the Budget Control Act of 2011. Sequestration reductions went into effect on April 1, 2013. FOR QUESTIONS PLEASE CONTACT US AT NEURO.US.REIMBURSEMENT@MEDTRONIC.COM ICD-10-CM 1 Diagnosis Codes Diagnosis codes are used by both physicians and hospitals to document the indication for the procedure. Medtronic Deep Brain Stimulation (DBS) Therapy is intended to manage the symptoms of the underlying conditions below. Because symptoms codes are generally not acceptable as the principal diagnosis, the principal diagnosis is coded to the underlying condition as shown. Essential Tremor 2 G25.0 Essential tremor Parkinson s Disease 2 G20 Parkinson s disease Dystonia Note: Humanitarian Device. The effectiveness of this device for the treatment of dystonia has not been demonstrated.

International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM). http:// www.cdc.gov/nchs/icd/icd10cm.htm. Updated October 1, 2016. Accessed November 30, 2016. 2. Essential tremor is treated with a single array neurostimulator generator. Parkinson s Disease is treated with a dual array neurostimulator generator. 3. When a device complication is the reason for the encounter, the device complication code is sequenced as the primary diagnosis followed by a code for the underlying condition. If the purpose of the encounter is directed toward the underlying condition or the device complication arises after admission, the underlying condition is sequenced as the primary diagnosis followed by the device complication code. 4. Device complication codes ending in A are technically defined as initial encounter but continue to be assigned for each encounter in which the patient is receiving active treatment for the complication (ICD-10-CM Official Guidelines for Coding and Reporting FY 2017, I.C.19.A). 5. According to ICD-10-CM manual notes, other specified complication includes erosion or breakdown of a subcutaneous device pocket. 6. Code Z45.42 is used as the principal diagnosis when patients are seen for routine device maintenance, such as periodic device checks and programming, as well as routine device replacement. A secondary diagnosis code is then used for the underlying condition. 7. U.S. Department of Health and Human Services, Centers for Medicare & Medicaid Services. International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS). http://www.cms.gov/medicare/coding/icd10/2017-icd-10-pcs-and-gems.html. Updated October 1, 2016. Accessed November 30, 2016. 8. Approach value 0-Open is used when leads are placed via craniotomy or craniectomy. Placement of a lead via burr hole is considered a percutaneous approach and uses approach value 3-Percutaneous (CMS ICD-10-PCS Reference Manual 2016, p.47). The same rationale can be applied to lead removal and replacement. 9. Codes defined as multiple array include dual array neurostimulator generators, a type of multiple array generator in which two leads are connected to one generator. Activa SC is a single-array non-rechargeable generator (device value B), Activa PC is a dual-array non-rechargeable generator (device value D), and Activa RC is a dual-array rechargeable generator (device value E). See also the ICD-10-PCS Device Index. Do not assign default device value M-Stimulator Generator. 10. Placement, removal and replacement of a neurostimulator generator is shown with the approach value 0-Open because creating the pocket requires surgical dissection and exposure. Removal also usually requires surgical dissection to free the device. 11. Body part value 6-Chest is shown because the generator is typically placed into the subcutaneous tissue of the chest. Other body part values are also available for sites such as subcutaneous tissue of abdomen and subcutaneous tissue of back. 12. CMS ICD-10-PCS Reference Manual 2016, p.67. 13. For lead revision, the ICD-10-PCS codes refer to surgical revision of the intracranial portion of the lead, eg, repositioning. For revision of the subcutaneous portion of the lead or revision of a subcutaneous extension, see Generator Revision. 14. The ICD-10-PCS codes shown can be assigned for opening the pocket for generator revision, as well as reshaping or relocating the pocket while reinserting the same generator. However, there are no ICD-10-PCS codes specifically defined for revising the subcutaneous portion of a lead or an extension. Because these services usually involve removing and reinserting the generator as well, they can also be represented by the generator revision codes. 15. Approach value X-External is also available for external generator manipulation without opening the pocket, eg. to correct a flipped generator. 3

HCPCS II Device Codes 1 These codes are used by the entity that purchased and supplied the medical device, DME, drug, or supply to the patient. For implantable devices, that is generally the facility. For specific Medicare hospital outpatient billing instructions for medical devices, see the Device C-Codes (Medicare) below. Note: The HCPCS II code for the lead is not shown because intracranial leads are not implanted on an outpatient basis. Pulse Generator 2 L8679 Implantable neurostimulator pulse generator, any type L8686 L8687 L8688 Implantable neurostimulator pulse generator, single array, non-rechargeable, includes extension Implantable neurostimulator pulse generator, dual array, rechargeable, includes extension Implantable neurostimulator pulse generator, dual array, non-rechargeable, includes extension Patient Programmer L8681 Patient programmer (external) for use with implantable programmable neurostimulator pulse generator, replacement only External Recharger L8689 External recharging system for battery (internal) for use with implantable neurostimulator, replacement only 1. Healthcare Common Procedure Coding System (HCPCS) Level II codes are maintained by the Centers for Medicare and Medicaid Services. http://www.cms.gov/medicare/coding/ MedHCPCSGenInfo/index.html Accessed November 30, 2016. 2. Effective January 2014, generator codes L8686-L8688 are not recognized by Medicare. Specifically for billing Medicare, code L8679 is available for physician use, while hospitals typically use C-codes and ASCs generally do not submit HCPCS II codes for devices. For non-medicare payers, codes L8686-L8688 remain available. However, all providers should check with the payer for specific coding and billing instructions. Device C-Codes 1 (Medicare) Medicare provides C-codes for hospital use in billing Medicare for medical devices in the outpatient setting. Although other payers may also accept C-codes, regular HCPCS II device codes are generally used for billing non-medicare payers. Unlike regular HCPCS II device codes, the extension is coded separately using C-codes. ASCs, however, usually should not assign or report HCPCS II device codes for devices on claims sent to Medicare. Medicare generally does not make a separate payment for devices in the ASC. Instead, payment is packaged into the payment for the ASC procedure. ASCs are specifically instructed not to bill HCPCS II device codes to Medicare for devices that are packaged. 2 Note: The C-code for the lead is not shown because intracranial leads are not implanted on an outpatient basis. Pulse Generator C1767 Generator, neurostimulator (implantable), non-rechargeable C1820 Generator, neurostimulator (implantable), with rechargeable battery and charging system Extension C1883 Adaptor/extension, pacing lead or neurostimulator lead (implantable) Patient Programmer C1787 Patient programmer, neurostimulator 1. Device C-codes are HCPCS Level II codes and are maintained by the Centers for Medicare and Medicaid Services. Healthcare Common Procedure Coding System. http:// www.cms.gov/medicare/coding/hcpcsreleasecodesets/alpha-numeric-hcpcs.html. Accessed November 30, 2016. 2. ASCs should report all charges incurred. However, only charges for non-packaged items should be billed as separate line items. For example, the ASC should report its charge for the generator. However, because the generator is a packaged item, the charge should not be reported on its own line. Instead, the ASC should bill a single line for the implantation procedure with a single total charge, including not only the charge associated with the operating room but also the charges for the generator device and all other packaged items. Because of a Medicare requirement to pay the lesser of the ASC rate or the line-item charge, breaking these packaged charges out onto their own lines can result in incorrect payment to the ASC.

Medtronic DBS for Essen al Tremor and Parkinson s Disease DBS THERAPY Device Edits (Medicare) 1 Medicare s procedure-to-device edits require that when certain CPT procedure codes for device implantation are submitted on a hospital outpatient bill, HCPCS II codes for devices must also be billed. Effective January 2015, the edits are broadly defined and may include any HCPCS II device code with any CPT procedure code used in earlier versions of the edits. 2 Within this context, the HCPCS II device codes shown below are both appropriate for the CPT procedure codes and will pass the edits. CPT Procedure Code CPT Code Description 3 61885 4,5 Insertion or replacement of cranial neurostimulator pulse generator or receiver, direct or inductive coupling; with connection to a single electrode array 61886 5 Insertion or replacement of cranial neurostimulator pulse generator or receiver, direct or inductive coupling; with connection to two or more electrode arrays HCPCS ll Device Codes C1767 C1767 C1820 HCPCS ll Code Description Generator, neurostimulator (implantable), non-rechargeable Generator, neurostimulator (implantable), non-rechargeable Generator, neurostimulator (implantable), with rechargeable battery and charging system 1.

In practice, HCPCS device code C1820 is not appropriate with CPT procedure code 61885 because rechargeable dual-array generators are used only with procedure code 61886. 5. HCPCS II L-codes L8686-L8688 will also pass the edits, but these codes are not shown because they are not otherwise recognized by Medicare. HCPCS II device code L8679 does not satisfy the edits. 5

Physician Coding and Payment January 1, 2017 December 31, 2017 CPT Procedure Codes Physicians use CPT codes for all services. Under Medicare s Resource-Based Relative Value Scale (RBRVS) methodology for physician payment, each CPT code is assigned a point value, known as the relative value unit (RVU), which is then converted to a flat payment amount.

However, there are different RVUs and payments depending on the setting in which the physician rendered the service. Facility includes physician services rendered in hospitals, ASCs, and SNFs. Physician RVUs and payments are generally lower in the Facility setting because the facility is incurring the cost of some of the supplies and other materials. Physician RVUs and payments are generally higher in the Physician Office setting because the physician incurs all costs there. 5. N/A shown in Physician Office setting indicates that Medicare has not developed RVUs in the office setting because the service is typically performed in a facility (eg, in a hospital). However, if the local contractor determines that it will cover the service in the office, then it is paid using the facility RVUs at the facility rate. Centers for Medicare & Medicaid Services.

Released November 2, 2016. Accessed November 30, 2016. 6. The AMA has published that placement of fiducials is integral to DBS lead implantation and is not coded separately. This is true even if the fiducials are placed during a separate encounter, in the physician s office, and/or on a different date prior to the lead implantation. CPT Assistant, October 2010, p.9. 7. Pre-operative CT and MRI imaging may be separately coded when they represent full-scale diagnostic imaging and the interpretation is documented via a formal imaging report. However, some payers may require imaging guidance codes such as 77011 and 77021 instead. Intra-operative imaging is part of surgical navigation and should not be coded separately. Note that although CPT code 61781 exists for computer-assisted intradural surgical navigation, CPT manual instructions and National Correct Coding Initiative (NCCI) edits do not allow this to be coded separately with lead implantation codes 61863 and 61867. 8. The 3D rendering codes are reported in addition to the code for the base CT or MRI procedure. 9. This assumes the service is occurring in the hospital facility, because the primary lead procedure must be performed in a facility. So the physician is providing the professional interpretation only (-26) and only facility RVUs and payments are displayed. 10. Surgical procedures are subject to a global period. The global period defines other physician services that are generally considered part of the surgery package. The services are not separately coded, billed, or paid when rendered by the physician who performed the surgery. These services include: preoperative visits the day before or the day of the surgery, postoperative visits related to recovery from the surgery for 10 days or 90 days depending on the specific procedure, treatment of complications unless they require a return visit to the operating room, and minor postoperative services such as dressing changes and suture removal. 11. When an existing lead is removed and replaced by a new lead, only the lead implantation code 61863-61867 may be assigned. For lead replacement, NCCI edits do not permit removal of the existing lead to be coded separately with placement of the new lead. 12. When an existing generator is removed and replaced by a new generator, only the generator replacement code 61885 or 61886 may be assigned. NCCI edits do not allow removal of the existing generator to be coded separately. Also note that, according to NCCI policy, use of the CPT code for generator insertion or replacement requires placement of a new pulse generator. When the same pulse generator is removed and then re-inserted, the revision code is used. NCCI Policy Manual 1/1/2017, p. VIII-8. 13. Medicare permits the use of bilateral modifier -50 with code 61885. To show bilateral placement of two single-array generator leads, submit 61885-50 with 1 unit.

CPT manual instructions and NCCI edits do not allow 95961-95962 to be coded separately with lead implantation when microelectrode recording is performed by the operating surgeon. However, the AMA has published that when another physician (eg, neurologist or neurophysiologist) performs the cortical or subcortical mapping during the placement of the electrode array, that physician may report codes 95961-95962 separately. CPT Changes 2004: An Insider s View, p.93. 15. According to CPT manual instructions, simple programming involves changes to three or fewer parameters and complex programming involves changes to four or more parameters. The parameters that qualify are: rate, pulse amplitude, pulse duration, pulse frequency, eight or more electrode contacts, cycling, stimulation train duration, train spacing, number of programs, number of channels, alternating electrode polarities, dose time (stimulation parameters changing in time periods of minutes including dose lockout times), more than one clinical feature (eg, rigidity, dyskinesia, tremor). (See also CPT Assistant, July 2016, p.7 and p.9.) 16. The AMA has published that, notwithstanding its definition, code 95971 should be used for simple programming of deep brain neurostimulators. CPT Assistant, October 2012, p.15. 17. According to CPT manual instructions, append modifier -52 for reduced services to code 95978 if complex programming lasts less than 31 minutes. 9

Hospital Outpatient Coding and Payment Effective January 1, 2017 December 31, 2017 CPT Procedure Codes Hospitals use CPT codes for outpatient services. Under Medicare s APC methodology for hospital outpatient payment, each CPT code is assigned to one of approximately 710 ambulatory payment classes. Each APC has a relative weight that is then converted to a flat payment amount. Multiple APCs can sometimes be assigned for each encounter, depending on the number of procedures coded and whether any of the procedure codes map to a Comprehensive APC. For 2017, there are 61 APCs which are designated as Comprehensive APCs (C-APCs). Each CPT procedure code assigned to one of these C-APCs is considered a primary service, and all other procedures and services coded on the bill are considered adjunctive to delivery of the primary service. This results in a single APC payment and a single beneficiary copayment for the entire outpatient encounter, based solely on the primary service. Separate payment is not made for any of the other adjunctive services. Instead, the payment level for the C-APC is calculated to include the costs of the other adjunctive services, which are packaged into the payment for the primary service. When more than one primary service is coded for the same outpatient encounter, the codes are ranked according to a fixed hierarchy. The C-APC is then assigned according to the highest ranked code. In some special circumstances, the combination of two primary services leads to a complexity adjustment in which the entire encounter is re-mapped to another higher-level APC. As shown on the tables below, DBS therapies are subject to C-APCs specifically for implantation, replacement, revision and removal of the generator. C-APCs are identified by status indicator J1. Note: Only procedures that can be performed in the hospital outpatient setting are shown. Intracranial lead implantation is not shown because it is not performed on an outpatient basis.

More broadly, these codes have status indicator Q3. For CT and MRI, status indicator Q3 shows that the service may be part of a composite APC if billed with other similar imaging services. However, within the context of services related to Medtronic DBS Therapy, the codes will generally be paid separately under the APCs, status indicators, and rates shown. 8.
