Monitor payer policy activity
Defines medical necessity, prior authorization requirements, and coverage criteria for surgical and associated procedures to treat TMJ disorder for HUSKY Health (Connecticut Medicaid) providers.
Introduction updated to reflect there is IQ criteria for arthroplasty procedures only and policy will be used for all other TMJ procedures.
Clinical Guideline restructured with the addition of criteria for meniscectomy, arthrotomy, and reconstruction procedures.
Procedure updated to include imaging reports as required clinical documentation.
Codes section updated to reflect code/procedure updates based on the changes with IQ criteria.
References updated to reflect current literature and resources.

inv-06: TMJ Procedure Criteria
Policy applies structured clinical guideline criteria for TMJ procedures; arthroplasty requires IQ criteria specifically.
Full IQ criteria text located elsewhere in the policy document
Full procedural criteria located elsewhere in the policy document
The performance of invasive surgery and associated procedures for temporomandibular joint (TMJ) disorder in individuals under the age of 18 years is considered investigational and therefore not medically necessary due to insufficient evidence supporting safety and clinical efficacy in peer‑reviewed literature.
No additional explicit exclusions are listed in the provided publication history or update notes for this policy beyond those already stated elsewhere in the document.
Surgery for TMJ disorder in individuals under the age of 18 years is categorized as not medically necessary (investigational) because current peer‑reviewed published evidence is insufficient to demonstrate safety and clinical effectiveness.
Within the provided update and publication history excerpts there are no additional standalone statements labeled as 'not medically necessary' beyond the age‑related investigational determination already documented.
Provider Requirements, Prior Authorization, and Documentation
Prior authorization required
Prior authorization is required for surgery and associated procedures for TMJ disorder; requests will be reviewed according to the procedures in place for surgical procedure reviews and based on submitted case-specific information.
Prior authorization and InterQual® criteria for arthroplasty
Prior authorization is required for covered TMJ surgical services to determine medical necessity; arthroplasty procedures specifically require review using InterQual® (IQ) criteria in addition to the policy's review process.
Conservative (non-surgical) therapy requirement
Surgery will be considered only after at least six (6) months of non-surgical treatment, including pharmacologic pain control, physical therapy, and intra-oral appliances, and when minimally invasive procedures are not feasible or have failed.
Meet structured criteria (IQ required for arthroplasty)
Approval for specified TMJ surgical procedures requires meeting the policy's structured clinical criteria; arthroplasty approval specifically requires meeting IQ criteria as described in the policy update.
Submit completed authorization request and clinical documentation
Submit a fully completed authorization request via the on-line web portal and include clinical documentation from the requesting physician, APRN, or PA supporting medical necessity.
- Fully completed authorization request via on-line web portal
- Clinical documentation from requesting physician, APRN, or PA
Include imaging reports with submission
Include imaging reports as required clinical documentation with the authorization submission to support the procedure request.
- Attach imaging reports outlined in the Clinical Guideline section
Denial risk if prior authorization not obtained
Failure to obtain required prior authorization for TMJ surgery and associated procedures may result in denial of coverage.
Incomplete documentation or unmet IQ criteria may trigger denial
Requests that lack required imaging reports or that do not meet IQ criteria for arthroplasty procedures may be denied or require additional review and information.
- Missing imaging reports can trigger denial or requests for more information
- Arthroplasty requests must meet IQ criteria or will be subject to additional review

Key Definitions and HUSKY Program Categories
Background and Clinical Context
The temporomandibular joint (TMJ) is a fibrocartilaginous sliding hinge joint with an articular disc and synovial membranes that enable speaking and chewing. TMJ disorder refers to clinical symptoms affecting masticatory muscles and the joint, such as restricted jaw mobility, facial or jaw numbness/tingling, and pain of the head, neck, or jaw. Surgical intervention may be considered only when specified clinical criteria are met — including the member being age 18 years or older, documentation of structural joint disorder, and persistent symptoms refractory to at least 6 months of non‑surgical therapy — and when minimally invasive options are not feasible or have failed. The policy update also clarifies that arthroplasty reviews require InterQual® criteria while meniscectomy, arthrotomy, and reconstruction procedures follow the restructured clinical guideline criteria added in this revision.
