Quick Explanation
This denial code indicates that the payer has rejected a claim or prior authorization request for an orthopedic procedure because the medical documentation does not demonstrate that a trial of conservative, non-surgical treatment was attempted first. Payers generally require a documented history of conservative management, such as physical therapy, injections, or medication, before approving invasive surgical interventions. Failing to meet these prerequisite step-therapy criteria results in a determination that the procedure was not medically necessary.
Common Causes for ORTHO01
Denials with code ORTHO01 typically happen for the following specific reasons:
- Lack of documented physical therapy (PT) or structured home exercise program (HEP) duration in the patient's clinical history.
- Failure to document specific trial periods and clinical outcomes of conservative pharmacological therapies, such as NSAIDs, oral steroids, or joint injections.
- Proceeding directly to major joint or spine surgery for a chronic condition without documenting why conservative treatments were bypassed or contraindicated.
- Submission of incomplete clinical notes during the prior authorization or billing process that omitted the timeline of prior non-operative interventions.
How to Prevent ORTHO01 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Utilize a pre-authorization checklist to verify that the patient's record contains explicit dates, durations, and outcomes of all conservative therapies prior to scheduling surgery.
- Ensure clinical documentation clearly details any medical contraindications to conservative therapy, such as progressive neurological deficits, that justify immediate surgical intervention.
- Educate providers on the necessity of documenting detailed patient compliance and response to non-operative treatments in the baseline history and physical (H&P) notes.
- Align scheduling and clinical workflows with payer-specific Local Coverage Determinations (LCDs) regarding mandatory conservative treatment durations.

Denial Code: ORTHO01 - Conservative treatment not attempted
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code ORTHO01: "Conservative treatment not attempted".
We are appealing the denial of the scheduled orthopedic procedure under denial code ORTHO01, asserting that the clinical indications meet all criteria for medical necessity. In accordance with milliman care guidelines (MCG) and standard orthopedic billing rules, conservative management was fully exhausted and documented in the patient's record prior to surgical recommendation. The attached medical records demonstrate that the patient underwent a compliant trial of conservative therapy, including physical therapy and pharmacological management, which failed to alleviate symptoms or restore functional capacity. Because further conservative delay would risk clinical deterioration, surgical intervention is the appropriate next step under CMS guidelines, and we request that this denial be overturned and the claim processed for payment.
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]
