General anesthesia is considered not reasonable and necessary for facet joint interventions. Neither conscious sedation nor monitored anesthesia care (MAC) is routinely necessary for intraarticular facet joint injections or medial branch blocks and are not routinely reimbursable.
So, under the current policy, a general anesthetic is always medically unnecessary in facet cases, while MAC may—in very limited circumstances—be reimbursed. Now, with a new series of Medicare announcements, the door to reimbursement that had been slightly ajar has now been slammed shut. Five Medicare contractors—Noridian, CGS, NGS, WPS and Palmetto—have developed a new policy that expressly bars reimbursement for anesthesia in connection with facet injections—regardless of anesthesia technique. The wording of the new policy is as follows: “Use of Moderate or Deep Sedation, General Anesthesia, and Monitored Anesthesia Care (MAC) is not considered medically reasonable and necessary during facet injections.”
The only redeeming aspect of the new policy is that it holds out the possibility of reimbursement for anesthesia in connection with facet radiofrequency ablation (RFA) procedures. On that score, the policy states: “Routine use of Moderate Sedation or Monitored Anesthesia Care (MAC) or use of General Anesthesia or Deep Sedation for RFA is not considered reasonable and necessary.” Note the operative words: “Routine use.” So, under certain rare and specified circumstances, MAC may be reimbursed by Medicare for facet RFA. What are those circumstances? Another document published by Noridian provides the contractor’s response to various submitted comments concerning the policy. The payer’s response relative to payment in RFA cases is as follows:
In cases where there is longstanding well-documented history of inability to cooperate, medical conditions that would prohibit performance of the procedure, or inability to remain motionless, anesthetic for facet RFA will be considered. The provider should document why the anesthesia is necessary for the individual patients.
Though two Medicare carriers (First Coast and Novitas) have yet to publish a similar update to their current facet policy, we expect their new policies to be released soon and to be consistent with the language found in the updated policies of the five other carriers. The new policy language will become effective on July 7 for Noridian, CGS and Palmetto. The effective date for the WPS policy is July 14, while the effective date for the NGS policy is August 1.
