Quick Explanation
This denial occurs when a healthcare payer determines that a billed therapeutic modality lacks sufficient clinical evidence, peer-reviewed scientific support, or FDA clearance to justify its medical necessity for the patient's specific condition. It indicates that the insurer classifies the treatment as experimental, investigational, or unproven for the diagnosed pathology. To overturn this denial, providers must establish that the treatment is clinically accepted and medically necessary through authoritative medical literature.
Common Causes for MH75
Denials with code MH75 typically happen for the following specific reasons:
- Billing for novel or emerging therapeutic modalities, such as certain low-level laser therapies or specific biofeedback techniques, that are not recognized under Local Coverage Determinations (LCDs) or National Coverage Determinations (NCDs).
- Utilizing a therapeutic modality for an off-label or clinically unproven diagnosis that is not supported by established evidence-based medicine guidelines.
- Failing to document standard conservative treatment failures in the patient's medical record prior to initiating the disputed modality.
- Submitting claims with non-specific procedure codes (e.g., unlisted physical medicine codes) without accompanying documentation demonstrating clinical efficacy and peer-reviewed backing.
How to Prevent MH75 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Review payer-specific medical coverage policies and LCDs/NCDs prior to administration to ensure the therapeutic modality is active, covered, and aligned with the patient's diagnosis.
- Implement a robust pre-authorization protocol for any non-standard, emerging, or specialized physical medicine and rehabilitation interventions.
- Obtain a signed Advance Beneficiary Notice (ABN) or pre-service waiver of non-coverage from the patient when administering modalities with restricted payer coverage.
- Ensure clinical documentation explicitly outlines the clinical rationale, physiological goals, objective functional deficits, and patient's response to the specific modality.

Denial Code: MH75 - Therapeutic modality not evidence-based
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code MH75: "Therapeutic modality not evidence-based".
We are appealing the denial of the billed therapeutic modality (CPT code) under denial code MH75. The clinical documentation submitted with this appeal demonstrates that the administered therapy was medically necessary, clinically appropriate, and directly correlated with the patient's documented functional improvement. Contrary to the assertion that this modality is not evidence-based, peer-reviewed clinical studies and guidelines from national professional organizations support the therapeutic efficacy of this treatment for the patient's specific diagnosis. Furthermore, standard conservative treatments had been exhausted without clinical resolution, making this targeted intervention the most appropriate course of care. We request that this denial be overturned and the claim be processed for payment based on the enclosed clinical evidence and medical necessity documentation.
Attached please find:
1. A copy of the original claim.
2. The relevant medical records supporting the service.
3. [Any other supporting documents].
We respectfully request that you reprocess this claim for payment.
Sincerely,
[Your Name]
