Is the treatment plan medically necessary and considered standard of care, proven safe and effective based on current medical standards, such as National Comprehensive Cancer Network (NCCN) or National Cancer Institute (NCI) guidelines?

Medical Necessity and Standard of Care Assessment

Without knowing the specific diagnosis, stage, and proposed treatment regimen, it is impossible to definitively determine whether a treatment plan is medically necessary or represents standard of care versus experimental therapy. 1

Critical Information Required for Assessment

To properly evaluate medical necessity and standard of care status, the following must be specified:

• Exact diagnosis with pathology confirmation including relevant biomarkers (e.g., PD-L1 expression, HER2 status, BRCA mutations) 1
• Complete staging information appropriate to the disease type (e.g., BCLC stage for hepatocellular carcinoma, TNM staging for solid tumors) 1
• Specific proposed interventions including drug names, doses, schedules, and combinations 1
• Patient-specific factors such as performance status, organ function, prior treatments, and contraindications 1

Framework for Determining Medical Necessity

A treatment plan meets medical necessity criteria when it satisfies three core requirements:

• Appropriate for the diagnosis and clinical stage based on pathologic confirmation 1
• Consistent with current evidence-based guidelines from recognized bodies such as NCCN, ASCO, NCI, or specialty-specific organizations 1
• Expected to improve morbidity, mortality, or quality of life rather than simply being mentioned in guidelines 1

Standard of Care Determination

Treatments are considered standard of care when they have NCCN Category 1 or 2A evidence levels or FDA approval for the specific indication. 1

NCCN Evidence Categories:

• Category 1: High-level evidence with uniform consensus 2
• Category 2A: Lower-level evidence with uniform consensus 2
• Category 2B: Lower-level evidence with consensus (but not uniform) 2
• Category 3: Major disagreement that intervention is appropriate 2

Examples of Standard vs. Non-Standard Care:

Standard of care examples:

• Pembrolizumab monotherapy for first-line metastatic NSCLC (including squamous cell) with PD-L1 ≥50%, no EGFR/ALK alterations, based on KEYNOTE-024 showing improved PFS (10.3 vs 6.0 months, HR 0.50) and OS (HR 0.63) 2
• High-dose chemotherapy followed by autologous stem cell transplant (HDT/ASCR) for chemosensitive relapsed/refractory Hodgkin lymphoma 2
• Weekly paclitaxel (80 mg/m²) for metastatic breast cancer, showing improved OS compared to every-3-week dosing (HR 0.78) 2

NOT standard of care examples:

• Bevacizumab for squamous cell lung cancer - contraindicated due to increased risk of fatal pulmonary hemorrhage (4 of 13 patients in phase II study) 2
• Nivolumab monotherapy for first-line NSCLC with PD-L1 ≥5% - failed to show benefit in CheckMate 026 (PFS 4.2 vs 5.9 months, HR 1.15; OS HR 1.02) 2
• Single-agent ipilimumab for first-line melanoma - superseded by superior options 1
• Tamoxifen, antiandrogens, or octreotide for hepatocellular carcinoma - demonstrated ineffective in trials 1

Common Pitfalls to Avoid

Do not assume all guideline-mentioned treatments are appropriate. Guidelines often list multiple options with different evidence levels and specific patient selection criteria. 1

Verify specific contraindications including:

• Organ dysfunction (e.g., renal function before IP cisplatin, hepatic function before hepatically-metabolized drugs) 2, 1
• Prior toxicities (e.g., preexisting neuropathy before taxanes, cardiac dysfunction before anthracyclines) 2
• Disease-specific contraindications (e.g., bevacizumab in squamous cell lung cancer) 2

Assess performance status appropriately. Patients with ECOG PS 3-4 are generally not eligible for systemic treatment; palliative care or best supportive care is recommended instead. 2

Experimental/Investigational Designation

Treatments are considered experimental or investigational when:

• Not included in NCCN guidelines for the specific indication 1
• Lack FDA approval for the labeled indication 1
• Listed as Category 3 (major disagreement) in NCCN guidelines 2
• Used outside established evidence without supporting data from recognized guideline bodies 1

Clinical trials represent the best management for any cancer patient and participation should be encouraged, but enrollment in a trial does not automatically make a treatment "standard of care" outside that trial context. 2

Documentation Requirements

Adequate documentation for medical necessity determination must include:

• Pathology confirmation with relevant biomarkers 1
• Staging workup results including appropriate imaging studies and laboratory tests 1
• Performance status assessment 2, 1
• Prior treatment history and response 2
• Organ function testing relevant to proposed therapy 2, 1
