Prior authorization required for TMS courses

Prior authorization is required for initial and repeat full intensive courses, maintenance, and extensions; authorization requests must include documentation of prior treatments and clinical response to support medical necessity.

• Includes prior treatment history, prior TMS response, and planned course length

Prior authorization for short/brief intensive TMS

Authorization for a short/brief intensive (mini/booster) course is implied by meeting medical necessity criteria: the record must document prior positive response or current worsening of symptoms, absence of recent short/brief intensive TMS within 90 days, and planned course length corresponding to symptom severity.

• Must document prior positive response or symptom worsening
• Not within 90 days of prior short/brief intensive course
• Planned number of treatments tied to severity (10/15/20)

Prior authorization for TMS with VNS (initial period)

Prior authorization may be required when TMS is used concurrently with an implanted vagus nerve stimulator (VNS); requests should indicate the intended limited-duration use (initial post-implant interval up to 3 months).

• Specify that TMS is intended during the initial 3-month post‑VNS implantation period
• Include evidence the patient recently completed a full or brief intensive TMS course and is transitioning to or undergoing maintenance TMS

Prior authorization should reflect transitional/maintenance intent with VNS

Prior authorization requests for TMS used with VNS should state whether TMS is intended as transitional or maintenance support after VNS implantation and include standardized rating-scale results to justify any extensions beyond the initial interval.

• Document whether TMS is transitional (just completed intensive course) or ongoing maintenance
• Include standardized depression rating-scale scores at interval completion to justify extension

Concurrent TMS with VNS — limited-duration authorization

Prior authorization is implied for concurrent TMS with VNS limited to the initial 3‑month post‑implant period and for up to three additional 3‑month intervals if VNS has not produced improvement to mild or remission on a standardized rating scale.

• Initial concurrent period: up to 3 months post‑VNS implantation
• Extensions: up to three additional 3‑month intervals contingent on standardized rating-scale evidence of inadequate VNS response

Prior authorization for planned concurrent TMS+VNS

Prior authorization should document planned use of concurrent TMS with VNS for up to 3 months (with possible extensions) while awaiting VNS effectiveness and must include prior treatment history and standardized rating-scale scores.

• Include prior TMS course details and dates
• Provide recent standardized rating-scale scores showing level of depression

Prior authorization limits for TMS with VNS

TMS provided in conjunction with VNS is limited by prior authorization to an initial 3‑month post‑implantation period and up to three additional 3‑month intervals while awaiting VNS effect; continued combined therapy beyond response or 12 months post‑implantation is not medically necessary.

• Stop when depression improves to mild or remission on a standardized scale or when 12 months have elapsed since implantation
• Each extension requires standardized rating‑scale evidence of lack of improvement

Prior authorization must reflect extension and stop rules with VNS

Prior authorization should indicate that TMS may be continued for up to 3 months after VNS implantation, with up to three additional 3‑month extensions only if standardized rating scales show no improvement to mild or remission; authorization must stop when improvement occurs or 12 months have elapsed since implantation.

• Provide VNS implantation date and interval dates
• Attach standardized rating-scale scores at each interval end showing lack of improvement

Prior authorization for continued TMS with VNS requires course and outcomes

Prior authorization requests for continued TMS with VNS should document prior TMS course and standardized rating-scale results supporting ongoing need; continued combined therapy is time-limited and contingent on documented insufficient VNS response.

• Document prior full or brief intensive TMS and timing relative to VNS implantation
• Include standardized depression rating-scale outcomes at interval completion

Prior authorization should include indication, TMS history, implant date, and scores

When seeking authorization for TMS used concurrently with VNS, include indication (Major Depressive Disorder), prior course of TMS (full/brief intensive and status), VNS implantation date, and standardized rating‑scale results documenting inadequate VNS response.

• Indication and dates
• Prior TMS course type and completion date
• VNS implantation date and interval requested
• Standardized rating‑scale scores showing lack of improvement

Authorization implied for concurrent TMS beyond implantation (time‑limited)

Prior authorization would be implied for TMS provided concurrently with VNS beyond implantation while waiting for VNS effect; approvals are limited to defined time intervals and contingent on clinical documentation showing need.

• Requests beyond initial interval must document lack of VNS improvement at prior interval end
• Authorization limited to specified 3‑month intervals

Prior authorization for continued TMS with VNS requires interval assessments

Prior authorization is implied for continuing TMS in conjunction with VNS beyond the initial post‑implantation window and for additional 3‑month intervals; documentation must support that VNS has not yet resulted in improvement to mild or remission on a standardized rating scale.

• Provide standardized rating‑scale assessments at completion of each interval
• Show that depression remains more than mild to justify continuation

Reauthorization required for each additional TMS+VNS interval

Prior authorization is required to continue TMS in conjunction with VNS beyond the initial 3‑month period and for each additional 3‑month interval; requests should include standardized depression rating‑scale scores and prior TMS course details.

• Each additional interval requires a new authorization with recent rating‑scale scores
• Include prior treatment dates and course specifics

Authorization should reflect initial 3‑month allowance and possible extensions

Prior authorization should state that TMS with VNS is allowed for up to an initial 3‑month period post‑implantation (or during transition to/continuation of maintenance TMS) and may be extended in up to additional 3‑month intervals if VNS has not produced improvement to mild or remission.

• Specify maximum of three additional 3‑month intervals
• Document decision rationale at each reassessment

Prior authorization may be required for continued TMS with VNS

Prior authorization is implied for continued TMS in conjunction with VNS beyond initial transition periods; medical necessity for continued TMS is limited to the specific intervals defined in policy and requires supporting documentation.

• Requests must reference the policy’s interval limits
• Provide evidence of prior TMS completion and current symptom severity

Medication step therapy required before TMS for MDD

Before initiating TMS for Major Depressive Disorder, document failure of at least three antidepressants from two or more classes, OR failure of at least two antidepressants from ≥2 classes plus failure of augmentation to one failed antidepressant.

• List medications tried, classes, durations, and outcomes

Treatment‑length thresholds tied to symptom severity

For short/brief intensive courses, document symptom severity to determine permitted treatment-length thresholds: mild = up to 10 treatments, moderate = up to 15, severe = up to 20.

• Record severity level and corresponding maximum number of treatments (10/15/20)

Sequencing: TMS may be used while awaiting VNS effect (transitional use)

TMS may be used temporarily while awaiting VNS effectiveness only when the individual has just completed a full or brief intensive TMS course and is transitioning to maintenance TMS or is undergoing maintenance TMS and TMS was partially but inadequately effective.

• Document completion date of recent intensive TMS course and maintenance status
• Show that prior TMS response was partial/inadequate

Extension criteria require standardized rating‑scale evidence

Extensions of concurrent TMS while awaiting VNS effectiveness require evidence at the end of each 3‑month interval that VNS has not resulted in improvement to mild or remission on a standardized rating scale.

• Provide standardized rating‑scale scores at each interval completion to justify extension

Document completion of intensive TMS and transition/maintenance status

Policy requires transition documentation: providers should document completion of a full or brief intensive course of TMS and the transition to or ongoing maintenance TMS when requesting concurrent TMS with VNS.

• Include dates of completed intensive TMS and description of maintenance regimen

Clinical sequencing requirement for concurrent TMS+VNS

Concurrent TMS with VNS is limited to cases where TMS was recently completed and is transitioning to maintenance, or where maintenance TMS was partially but inadequately effective; do not request concurrent TMS outside these clinical sequencing scenarios.

• Clearly state clinical rationale tying TMS use to transition/maintenance context

Required clinical documentation for authorization

Providers must document age, current episode severity (symptoms or standardized rating scales), prior medication trials (number, classes, augmentation), neurologic clearance when indicated, and treatment planning/motor threshold determinations when performed.

• Age and indication
• Standardized rating‑scale scores or symptom documentation
• Prior medication trial details (agents, classes, durations, outcomes)
• Neurologic clearance documentation when brain lesion/head trauma/tumor present
• Records of treatment planning, cortical mapping, and motor threshold determinations

Treatment course documentation (dates, sessions, mapping)

Document treatment course details: treatment dates, number of sessions, any motor threshold re‑determinations and reasons, and specifics when accelerated, continuation, maintenance, or taper schedules are used.

• Dates and counts of sessions
• Motor threshold re‑determination occurrences and rationale
• Description of taper, continuation, or maintenance schedule used

Document clinical response and symptom severity or prior TMS response

Documentation must demonstrate prior positive response to TMS or current worsening of depression/OCD symptoms via clinical notes or a standardized rating scale; symptom severity documentation determines course length eligibility.

• Clinical notes describing response or worsening
• Standardized rating‑scale scores to support severity and need

Documentation required when TMS is used with recent VNS implantation

If TMS is used while awaiting VNS efficacy after implantation, documentation should show the individual completed a full or brief intensive course of TMS and is transitioning to maintenance or was on maintenance with partial/inadequate effect.

• Date of most recent intensive TMS completion
• Statement that TMS was partially but inadequately effective or that patient is transitioning to maintenance

Concurrent TMS+VNS documentation must show transitional timing and scores

For concurrent TMS+VNS, documentation must support that use is limited to defined transitional periods (initial 3 months and any additional 3‑month intervals) and include standardized rating‑scale results showing whether depression improved to mild or remission.

• Evidence that concurrent use is within the initial 3‑month window or a justified extension interval
• Standardized rating‑scale scores at interval completion

Required documentation when continuing TMS with VNS (implant date + scores)

When continuing TMS with VNS, include standardized rating‑scale results demonstrating whether depression has improved to mild or remission and the VNS implantation date to justify continued TMS or any extension.

• VNS implantation date
• Standardized rating‑scale scores demonstrating lack of improvement to mild/remission

Document standardized rating‑scale outcomes to justify extensions

Requests to extend concurrent TMS with VNS must include standardized rating‑scale scores showing lack of improvement to mild or remission at the end of the prior interval.

• Attach interval-end standardized rating‑scale scores to support continuation requests

Document rating scales and implantation date; provide recent assessments

Clinical documentation should include standardized rating‑scale scores at interval completions and VNS implantation date to apply the 12‑month limit; attach recent standardized assessments and TMS course dates to support interval limits and maintenance transitions.

• Standardized rating‑scale scores at each interval completion
• Dates of TMS courses and VNS implantation
• Recent assessment showing depression level

Standardized rating‑scale documentation required to stop concurrent TMS

Clinical measurement of depression severity using a standardized rating scale is required to determine improvement to mild or remission and thus whether continued concurrent TMS is medically necessary.

• Use standardized rating scales to demonstrate whether depression reached mild or remission thresholds

Provide recent standardized assessments and timing for interval decisions

Documentation should demonstrate recent standardized rating‑scale assessments showing level of depression (e.g., mild or remission) and dates of VNS implantation and TMS courses to support interval limits and transitions to maintenance TMS.

• Recent standardized scale scores
• Dates of VNS implantation and prior TMS courses

Required documentation elements for TMS+VNS authorization

Required documentation elements for TMS with VNS: timing of VNS implantation, prior course of TMS (full or brief intensive), whether individual is transitioning to or undergoing maintenance TMS, and standardized rating‑scale scores showing lack of improvement to mild or remission for extensions.

• VNS implantation date and interval requested
• Prior TMS course type and completion date
• Standardized rating‑scale scores demonstrating inadequate VNS response

Clinical status and timing documentation to justify continuation

Documentation should show standardized rating‑scale scores demonstrating whether depression remains more than mild to justify continued TMS, and include dates of VNS implantation to track the 12‑month cumulative limit and 3‑month intervals.

• Interval scoring showing depression > mild
• VNS implantation date to track elapsed time

Provide scores and timing to justify continued TMS with VNS

Required documentation for continued TMS with VNS must demonstrate standardized rating‑scale scores showing whether depression has improved to mild or remission and timing relative to VNS implantation to support continued medical necessity.

• Standardized rating‑scale scores and dates
• Timing relative to VNS implantation

Contraindications to document or obtain clearance (may trigger denial)

Do not authorize TMS when contraindications are present; document absence of these issues or provide specialist clearance. Contraindications that may trigger denial include brain tumor or lesion without neurologist/neurosurgeon clearance, recent severe head trauma without clearance, uncontrolled seizure disorder, active psychosis or substance abuse, non‑removable magnetic‑sensitive implants within 30 cm of coil, and dental implants with magnetically sensitive material on treatment side.

• If brain tumor/lesion or severe head trauma present, provide neurologist/neurosurgeon clearance
• Document seizure disorder stability on medication
• Confirm absence of non‑removable magnetic‑sensitive implants within 30 cm of coil

Avoid consecutive/overlapping courses for different conditions

Consecutive or overlapping courses for different conditions (for example, MDD followed by OCD) are considered not medically necessary; avoid concurrent or overlapping authorizations for different diagnoses.

• Ensure prior courses for other conditions are not overlapping
• Do not authorize consecutive courses for different conditions without meeting criteria

Multiple concurrent courses or providers will risk denial

Consecutive or overlapping courses of TMS for different conditions or TMS provided by more than one provider/group/clinic at the same time are considered not medically necessary and may be denied; ensure single‑provider continuity and non‑overlap.

• Confirm single provider/clinic is delivering TMS
• Do not approve overlapping courses for different diagnoses

TMS combined with Spravato/ketamine/other psychedelics is investigational

Use of TMS in conjunction with Spravato, any form of ketamine, or any other psychedelic drug is considered investigational and may trigger denial; do not request concurrent authorization for combined psychedelic therapies.

• Declare if any psychedelic drug (Spravato, ketamine, others) is being used concurrently — such combinations are investigational

Avoid multiple‑provider simultaneous TMS

TMS provided by more than one provider/group/clinic at the same time is considered not medically necessary and may be a basis for denial; ensure documentation shows a single treating provider/clinic.

• Provide evidence of single treating provider/clinic and treatment coordination

Denial risk: stop concurrent TMS when scale shows mild or remission

Continued TMS in conjunction with VNS is considered not medically necessary when depression has improved to mild or remission based on a standardized rating scale; documentation of improvement to mild/remission will be a basis for denial of further concurrent TMS.

• Provide standardized rating‑scale scores showing whether depression reached mild or remission — if so, continued TMS is not medically necessary

Denial risk after 12 months post‑VNS implantation

Continued TMS in conjunction with VNS is considered not medically necessary when 12 months have elapsed since VNS implantation; include implant date to determine elapsed‑time denial risk.

• VNS implantation date must be documented — requests beyond 12 months post‑implantation are not medically necessary

Denial triggers for continued TMS with VNS (scores or elapsed time)

Continued TMS with VNS is not medically necessary when depression improves to mild or remission on a standardized rating scale or when 12 months have elapsed since VNS implantation; include interval‑end scores and implant date to determine denial triggers.

• Either improvement to mild/remission or 12 months elapsed terminates medical necessity for concurrent TMS

Document completion of intensive TMS and rationale for maintenance/transition use

Providers should document completion of a full or brief intensive TMS course and the reason for transitioning to maintenance or continuing TMS with VNS; this documentation supports authorization and sequencing expectations.

• Document why maintenance/transition TMS is clinically indicated after recent intensive course
