Diagnosis and Disease Status
Primary diagnosis: [Diagnosis] — [ICD-10 code if known]
Histology/subtype: [Histology/subtype]; Date of initial diagnosis: [Date or approximate month/year]
Current stage/disease category: [AJCC/TNM if applicable; otherwise localized / locally advanced / metastatic / relapsed / refractory]; Staging basis: [Imaging / Pathology / Clinical] — [Date]
Sites of disease: [List sites with imaging dates] (Include if metastatic.)
- Pathology: [Specimen site]; [Procedure type]; [Report date]; [Key findings including grade, receptors/mutations if applicable]
- Imaging evidence: [Modality]; [Date]; [Pertinent findings quantifying burden or progression]
- Tumor markers: [Marker] — [Values with dates showing trend] (Include only if clinically used for this malignancy.)
- Performance status: [ECOG / Karnofsky] — [Date assessed]
- Organ function relevant to regimen safety: [Renal: Cr, eGFR — date]; [Hepatic: AST/ALT, bilirubin — date]; [Hematologic: ANC, Hgb, Plt — date] (Include only values pertinent to safety thresholds for requested regimen.)
- Comorbidities/contraindications affecting regimen choice: [List with brief relevance and dates of key events]
- Pending studies impacting regimen: [Test name]; [Ordered date]; [Expected date]; [Whether regimen is contingent vs. bridging approach] (Omit if none pending.)
Prior Therapies and Outcomes
(Include for non–first-line requests. Explicitly connect prior failures to step-therapy criteria where applicable.)
| Line | Regimen | Dates | Best Response — Evidence Source | Reason Stopped |
|---|---|---|---|---|
| [Line number] | [Regimen name] | [Start – Stop] | [CR / PR / SD / PD] — [Imaging / lab / symptom source, date] | [progression / toxicity / completion / other]; [Toxicity type and grade if applicable] |
(Add rows as needed for additional lines of therapy.)
- Residual or unresolved toxicities affecting future therapy: [List with current grade/severity and dates]
- Relevant surgery: [Procedure]; [Date]; [Key outcome: margins/pathology] (Include only if impacts current request.)
- Relevant radiation: [Site/dose/fractions]; [Dates]; [Response/toxicity] (Include only if impacts current request.)
Requested Therapy
Regimen: [Regimen name and components]
Indication: [Diagnosis]; [Stage/disease status]; [Line of therapy]
Intent: [curative / adjuvant / neoadjuvant / consolidation / maintenance / palliative]
Route and Setting: [IV / SC / oral]; [infusion center / specialty pharmacy / home infusion]
Dosing and Schedule: [Cycle length]; [Days of administration]; [Frequency]; [Planned number of cycles or duration criteria]
Patient metrics for dosing: [Weight with date]; [Height with date]; [BSA with date] (Include if weight/BSA-based dosing.)
Planned dose adjustments: [Adjustments for renal/hepatic impairment or other factors with clinical rationale] (Include only if applicable.)
For oral agents: [Daily dose]; [Quantity/days supply]; [Refills requested] (Include only for oral oncolytics.)
Drug codes: [HCPCS J-code]; [NDC] (Include if required by payer.)
Supportive care relevant to approval: [Required premedications]; [Growth factor support]; [Prophylaxis required by regimen] (Omit routine items not tied to approval criteria.)
Medical Necessity Rationale
- Guideline/compendia basis: [Guideline or compendia name, version, date] — [Category/level of evidence if applicable] (If off-label, explicitly state and cite compendia category or peer-reviewed literature.)
- Patient-specific eligibility alignment: [Stage/disease status]; [Biomarker status with dates]; [Prior lines completed]; [Contraindications to alternatives]; [Organ function parameters meeting safety thresholds]
- Alternative therapies and why not appropriate:
- [Alternative 1] — [Reason: prior failure with date / contraindication / inferior efficacy for biomarker profile / unacceptable toxicity risk]
- [Alternative 2] — [Reason not appropriate]
- [Additional alternatives as relevant]
- For continuation requests: [Objective benefit: radiographic / biochemical / symptomatic response with evidence and dates]; [Current tolerability and toxicity management]; [Why continuation is medically necessary vs stopping/switching] (Include only for continuation requests.)
- For non-preferred product/site exceptions: [Clinical reason: prior reaction, documented medical exception, device/administration constraints, site-of-care safety considerations] (Include only if requesting non-preferred product or site.)
Safety and Monitoring Plan
- Baseline assessments completed: [Labs with dates]; [Cardiac imaging if applicable with date]; [Screening tests with dates]
- On-treatment monitoring: [Lab frequency]; [Imaging/response assessment cadence]; [Toxicity monitoring approach]
- Dose modification strategy: [General thresholds for hold/reduce/discontinue per guideline or label] (Summarize at high level; do not paste full protocol.)
Time Sensitivity
- Objective trigger: [Imaging or clinical finding with date showing progression, organ compromise, or symptomatic burden]
- Clinical window: [Specific timeframe and consequence of delay, e.g., "Delay beyond X days/weeks risks loss of curative window / organ failure / hospitalization"]
(For Standard priority requests, note relevant timing such as adjuvant start goal post-operatively or surveillance interval. For Expedited-Urgent, must include patient-specific harm statement with objective data.)
Supporting Documentation
- [Pathology report — date — Confirms diagnosis/histology/subtype]
- [Molecular/biomarker report — date — Lists actionable markers guiding therapy] (Note if pending with expected date.)
- [Imaging report(s) — date — Staging or progression documentation]
- [Recent clinic note — date — Performance status and treatment discussion]
- [Pertinent labs — date — Baseline organ function/safety parameters]
