Occlusal adjustment coding creates confusion for many dental practices navigating the distinction between limited and complete procedures. D9952 represents the billing code for comprehensive occlusal adjustments that address bite discrepancies across multiple teeth or the entire arch. Understanding when to apply D9952 versus D9951 protects your practice from claim denials while ensuring appropriate reimbursement for bite correction procedures. This guide clarifies the clinical scenarios, documentation standards, and billing practices that support compliant use of this procedure code.

What is Dental Code D9952?
D9952 defines complete occlusal adjustment performed to correct bite discrepancies affecting multiple teeth or full arches. The code applies when a dentist performs comprehensive reshaping of biting surfaces to improve how upper and lower teeth come together.
Complete occlusal adjustment under D9952 involves systematic evaluation and modification of occlusal contacts across multiple teeth rather than isolated adjustments to one or two teeth. This distinction separates comprehensive bite correction from limited adjustments that address localized issues.
Common Terminology
Understanding the language surrounding D9952 ensures accurate application and documentation:
Complete occlusal adjustment: Comprehensive bite correction involving multiple teeth or full arches requiring systematic evaluation and modification
Limited occlusal adjustment (D9951): Localized bite correction addressing one or two teeth
Occlusal contacts: Points where upper and lower teeth meet during biting and chewing
Premature contact: An area where teeth touch too early or too heavily, disrupting normal bite function
Centric relation: The position of the jaw when properly aligned, used as a reference for occlusal adjustments
When is D9952 Used?
D9952 applies specifically to scenarios requiring comprehensive bite correction across multiple teeth or arches. The code captures the clinical value and time investment of systematic occlusal evaluation and adjustment rather than spot corrections.
Proper application requires that the adjustment involves multiple teeth and follows a deliberate diagnostic process to identify and correct bite discrepancies affecting overall occlusal function.
Common Clinical Scenarios
D9952 appropriately documents the following interventions:
Comprehensive bite adjustment following full-mouth rehabilitation or extensive restorative work affecting multiple teeth
Correction of occlusal discrepancies causing TMJ symptoms, jaw pain, or muscle tension that requires adjustment of contacts across multiple teeth
Systematic occlusal equilibration to address wear patterns affecting multiple teeth in one or both arches
Post-orthodontic bite refinement requiring adjustment of multiple teeth to achieve stable occlusion
Management of bruxism-related bite problems requiring comprehensive evaluation and adjustment of multiple occlusal contacts
Correction of occlusal trauma patterns affecting periodontal health across multiple teeth
When D9952 is NOT Appropriate
Several scenarios fall outside the intended use of this code:
Minor adjustments to a single crown or filling causing localized discomfort (use D9951 for limited adjustment)
Routine post-operative adjustment of a single restoration during the global period of the original procedure
Adjustments performed as part of another procedure's standard protocol (such as minor bite adjustment during crown delivery)
Orthodontic appliance adjustments (these fall under orthodontic treatment codes)
Adjustments to dentures or removable prosthetics (these have separate adjustment codes)
Simple spot grinding of one or two teeth without comprehensive occlusal evaluation
Billing and Insurance Considerations
Successful reimbursement for D9952 depends on comprehensive documentation that establishes medical necessity and supports the scope of treatment. Insurance carriers scrutinize complete occlusal adjustment claims to ensure services represent legitimate comprehensive procedures rather than routine single-tooth adjustments.
Clear clinical narratives that describe presenting symptoms, diagnostic findings, number of teeth involved, and treatment rationale strengthen claims and reduce the likelihood of denial or requests for additional information.
Documentation Requirements
Complete documentation for D9952 claims includes several critical elements:
Clinical notes needed: Detailed description of presenting symptoms including pain location, jaw dysfunction, wear patterns, or other occlusal problems; comprehensive examination findings supporting the need for complete adjustment; specific diagnostic process used to identify occlusal discrepancies; number of teeth adjusted and rationale for comprehensive rather than limited approach; patient's response to treatment and functional improvement achieved
Diagnostic documentation: Pre-treatment photographs showing wear patterns, occlusal relationships, or bite discrepancies when visible; articulated study models if used for diagnosis and treatment planning; notation of specific occlusal contacts identified as problematic; documentation of jaw position evaluation (centric relation assessment)
Treatment records: Systematic documentation of which teeth were adjusted and why; notation of adjustment technique and extent of modification; verification of final occlusal relationships and patient comfort
Insurance Coverage
Coverage for D9952 varies significantly across carriers and plan types:
Many dental insurance plans provide benefits for occlusal adjustments as part of basic or major services, depending on the plan structure
Some carriers classify D9952 as a preventive service when performed to prevent further dental problems, while others categorize it as a basic or major procedure
Annual maximum benefits typically apply to occlusal adjustments unless the plan specifically exempts certain preventive services
Frequency limitations often apply, with many carriers restricting coverage to one complete occlusal adjustment per year or per multi-year period
Some plans require the procedure to be performed in conjunction with other covered services (such as after completing extensive restorative work) rather than as a standalone treatment
Pre-authorization requirements vary by carrier, with some requiring prior approval for D9952 when performed as an isolated procedure
Common Billing Mistakes
Avoiding these frequent errors protects practice revenue and maintains compliance:
Using D9952 for simple single-tooth adjustments that should be coded as D9951 (limited occlusal adjustment)
Billing D9952 during the global period of recently completed restorative work when minor bite adjustment is considered part of the original procedure
Failing to document the number of teeth adjusted and the systematic diagnostic process that justifies a complete rather than limited adjustment
Submitting claims without adequate clinical notes explaining why comprehensive adjustment was medically necessary
Billing D9952 multiple times within short timeframes without clear documentation of distinct clinical indications for repeated comprehensive adjustments
Confusing occlusal adjustment codes with equilibration performed as part of TMJ treatment or other separate procedures
Inadequate documentation of pre-treatment symptoms and post-treatment improvement in function
Common Questions
How often can D9952 be billed?
No universal limit exists for billing D9952, but carriers typically allow one complete occlusal adjustment per year or per multi-year period based on clinical necessity. Multiple D9952 codes within a short timeframe require comprehensive documentation explaining why repeated complete adjustments are clinically indicated. Patterns suggesting routine use of the complete adjustment code for simple single-tooth corrections may trigger an audit or claim denial.
Can D9952 be billed with the same date of service as other procedures?
D9952 can appear alongside other codes when the occlusal adjustment represents a distinct procedure separate from routine post-operative adjustments. For example, comprehensive occlusal adjustment performed weeks after completing full-mouth rehabilitation represents appropriate billing. However, billing D9952 for bite adjustment performed immediately following crown or bridge delivery during the same appointment typically results in denial, as minor post-operative adjustment is considered part of the restorative procedure.
Does D9952 require pre-authorization?
Pre-authorization requirements vary by carrier. Some plans require prior approval for D9952 when performed as an isolated procedure without accompanying restorative work, while others do not mandate pre-authorization. Practices should verify carrier-specific policies before treatment to establish patient cost responsibility and avoid claim denials based on authorization requirements.
What is the difference between D9951 and D9952?
D9951 represents limited occlusal adjustment involving one or two teeth, often performed to correct a localized bite problem such as a high restoration. D9952 specifically addresses complete occlusal adjustment involving systematic evaluation and modification of multiple teeth or full arches. The scope of treatment and number of teeth involved distinguish these codes.
Can D9952 be billed for adjustments following orthodontic treatment?
Yes, when post-orthodontic bite refinement requires comprehensive adjustment of multiple teeth to achieve stable occlusion. However, if the adjustment is minor or part of routine orthodontic finishing, it should be included in the orthodontic treatment code rather than billed separately. Clear documentation of the scope and medical necessity of comprehensive adjustment supports appropriate billing.
Should occlusal adjustment performed as part of full-mouth rehabilitation be billed separately?
This depends on timing and scope. Minor bite adjustments performed during the delivery appointments of restorative work are typically considered part of the restorative procedures and should not be billed separately. However, if comprehensive occlusal adjustment is performed weeks or months after completing restorative work to address functional problems that have emerged, D9952 may be appropriate with proper documentation.
