Having undergone back surgery at the age of twenty-seven, I would tell you that yes I needed that back surgery. Whether or not my chart demonstrated that need or not, who knows. That was then and this is now and in the current Medical Review Contractor environment, if the documentation in a medical record does not support the medical necessity of the procedure, claims submitted by hospitals and in some instances the surgeon can and are being denied.

There are countless types of back surgeries but for this article the focus is on documentation required to support the medical necessity of lumbar spinal fusions that code to DRGs 459 (Spinal Fusion Except Cervical with Major Co-morbidity or Complication) and DRG 460 (Spinal Fusion Except Cervical without Major Co-Morbidity or Complication).

Who is Looking?

The CMS Inpatient Hospital Reviews webpage indicates that despite the current Medicare Administrative Contractor (MAC) Probe & Educate Program, “MACs, Recovery Auditors and the Supplemental Medical Review Contractors will continue other types of inpatient hospital reviews” including “reviews for the medical necessity of a surgical procedure provided to a hospitalized beneficiary.”

MACs

Jurisdiction-N (J-N): First Coast Services Options, Inc.

First Coast is the MAC for Florida and in the absence of a National Coverage Determination (NCD) they were the first and to date the only MAC to have a Local Coverage Determination (LCD) for Spinal Fusions. LCD L32074: Lumber Spinal Fusion for Instability and Degenerative Disc Conditions had an original effective date for services performed on or after October 16, 2011.

Key LCD Guidance

• It is “when conservative therapy (non-surgical medical management) is unsuccessful after at least 3 to 12 months, depending on the diagnosis, lumbar spinal fusion may be considered for certain conditions.”
• “The hospital records are the primary source of information for the audit of hospital/procedure services. Therefore, any historical data supporting the medical necessity of the fusion (for example, duration and outcome of physiotherapy, injection therapy, anatomic factors influencing the decision for surgery, etc.) must be included in the inpatient medical record as noted in the history and physical examination, operative note and/or copies of office notes. For example, fusion of iatrogenic instability (i.e., surgical resection of facet as essential portion of the required decompression rendering an unstable segment) should be documented in a pre-operative note and/or an operative note.”
• “To meet Medicare’s reasonable and necessary (R&N) threshold for coverage of a procedure, the physician’s documentation for the case should clearly support both the diagnostic criteria for the indication (standard test results and/or clinical findings as applicable) and the medical need (the procedure does not exceed the medical need and is at least as beneficial as existing alternatives & the procedure is furnished with accepted standards of medical practice in a setting appropriate for the patient’s medical needs and condition). Lacking compelling arguments for an exception in the supporting documentation, the hospital (FISS claim) and physician services (MCS claim) can be denied.”
• Physician documentation must support the need for surgery and “must include the following:
• Office notes/hospital record, including history and physical by the attending/treating physician
• Documentation of the history and duration of unsuccessful conservative therapy (non-surgical medical management) when applicable. Failure of non-surgical medical management can be historical and does not have to be under the direction of the operating surgeon.
• Interpretation and reports for X-rays, MRI’s, CT’s, etc.,
• Medical clearance reports (as applicable)
• Documentation of smoking history, and that the patient has received counseling on the effects of smoking on surgical outcomes and treatment for smoking cessation if accepted (if applicable)
• Complete operative report outlining operative approach used and all the components of the spine surgery

Medical record documentation must be made available to Medicare upon request. When the documentation does not meet the criteria for the service(s) rendered or the documentation does not establish the medical necessity for the service(s), such service(s) will be denied as not reasonable and necessary under Section 1862(a)(1)(A) of the Social Security Act.”

Jurisdiction-11 (J-11) Palmetto GBA

Palmetto, the MAC for North Carolina, South Carolina, Virginia and West Virginia posted the YouTube Presentation Clinical Updates: DRG 459, 406earlier this year on August 11th. The most common reason cited by Palmetto for denials was a lack of information in the medical record about the conservative care provided prior to the surgical intervention.

Palmetto goes on to list documentation examples of conservative treatment that when clearly documented may help support payment for spinal fusion-related hospital care. Physical therapy, joint injections, neurologic deficits and upper and lower extremity strength are just a few of the examples provided.

Cahaba GBA, the MAC for Alabama, Georgia and Tennessee, has on more than one occasion indicated that simply documenting “failed outpatient therapy” for a total joint replacement is not sufficient to support the surgery. Similarly, Palmetto notes in this presentation that “failed outpatient therapy, admit for spinal fusion” is not sufficient evidence of Medical Necessity for a spinal fusion.

Supplemental Medicare Review Contractor (SMRC)

Transmittal 508 had an Effective and Implementation date of April 8, 2014 and added the Supplemental Medicare Review Contractor (SMRC) to the already long list of “Review Contractors” (MACs, CERT, RAC, PSCs, and ZPICs) performing medical review activities.

Strategic Health Solutions, LLC was awarded the SMRC Contract and they have been busy this year fulfilling one of their primary tasks of “conducting medical review based on the analysis of national claims data versus data that is limited to a specific jurisdiction as performed by Medicare Administrative Contractors (MACs).”

One such Project was a review of Medicare Part A Inpatient Services for Spinal Fusions. As part of the Project Background they noted that “analysis of Medicare claims data for calendar years 2012 and 2013 indicated a significant increase in billing and payment in Inpatient Hospitals Stays of Diagnosis-Related Group (DRG) Codes 459 (Spinal Fusion, except cervical spine, with major complications or comorbidities) and 460 (Spinal Fusion, except cervical spine, without major complications or comorbidities).”

The purpose of this project was to determine if claims had been appropriately adjudicated according to Medicare regulations and guidelines. At the end of the project 986 claims had been reviewed. Of those claims 589 were denied due to no response from the hospital and 374 claims were denied after review with a resultant overall Error Rate of 49%.

Project findings also included Specific Denial Reasons and Ways to Prevent Denials.

Denial Reasons

• Providers not responding to Additional Documentation Request (ADR) within the 45 day time frame
• Lack of documentation supporting the medical necessity of the procedure.
• Lack of documentation showing that conservative treatment was done prior to the surgical intervention.

Ways to Prevent Denials

• “Responding timely to SMRC ADR letters,
• Submit all documentation related to the services billed which support the medical necessity of services billed.”

Moving forward, hospitals need to be aware of NCD and LCD requirements to ensure records support the medical necessity of a procedure, be mindful of all of the Review Contractors that could be requesting records and submit requested information within the allowed time frame.
