DecisionDx-Melanoma Genomic Testing
DecisionDx-Melanoma, Castle Biosciences’ flagship 31-gene expression profile test, quantifies metastatic risk for invasive cutaneous melanoma by giving a personalized probability of recurrence to guide surgery and surveillance; studies show a hazard ratio ~4.5 for high-risk vs low-risk cohorts (peer-reviewed through 2024).
The test’s biological signature analysis is supported by >4,500-patient validation data and inclusion in NCCN and ASCO guideline discussions as of 2024, cementing market leadership in dermatology molecular prognostics.
Commercially, DecisionDx-Melanoma drove Castle’s revenue growth—about $175 million in total revenue in 2024—with dermatology segment growth year-over-year near 20%, reflecting strong clinician adoption and payer coverage expansion.
DecisionDx-SCC for Cutaneous Squamous Cell Carcinoma
DecisionDx-SCC for cutaneous squamous cell carcinoma is a prognostic genomic test that stratifies patients with high-risk SCC by likelihood of nodal or distant metastasis, guiding clinicians toward adjuvant radiation or intensified nodal surveillance; studies through 2025 show a hazard ratio ~3.5 for metastasis in high- versus low-risk groups. It has driven adoption at major cancer centers, contributing to Castle Biosciences’ dermatology revenue, which rose 18% in 2024 to $160 million, and saw test volumes increase ~40% year-over-year by late 2025.
TissueCypher Barretts Esophagus Test
Acquired to diversify Castle Biosciences into gastroenterology, TissueCypher Barretts Esophagus uses spatial omics to predict 5-year progression risk to esophageal adenocarcinoma, with published hazard ratios ~3.5 and reported negative predictive value >95% in low-risk groups (2024 data).
The test gives physicians actionable intelligence to choose endoscopic eradication therapy versus surveillance; studies show it reclassifies ~30% of management plans and can reduce unnecessary ER visits and procedures.
Financially, TissueCypher is a strategic growth pillar beyond dermatologic oncology; Castle projected mid-single-digit revenue contribution in 2025 and expects addressable GI market expansion to ~$500M by 2028 per industry estimates.
IDgenetix Pharmacogenomic Testing
IDgenetix Pharmacogenomic Testing analyzes genetic variants to guide medication choice and dosing for depression and anxiety, cutting trial-and-error prescribing and improving remission rates—studies show pharmacogenomics can increase response by ~21% and reduce adverse events by ~39%.
By lowering hospitalizations and ineffective prescriptions, it can reduce per-patient annual costs by several hundred dollars; it positions Castle Biosciences as an entry into a mental health diagnostics market projected to reach $9.5B by 2028.
- Improves response ~21%
- Reduces adverse events ~39%
- Potential per-patient cost savings: hundreds $/yr

Medicare Reimbursement and PLA Codes
Private Payer Contracting Strategy
Castle Biosciences aggressively pursues contracts with commercial insurers to expand covered lives for its genomic tests; by Q3 2025 they reported 120 million commercially covered lives, up from 80 million in 2023.
Negotiations lean on peer-reviewed cost-effectiveness studies showing melanoma and skin-cancer genomic testing can cut downstream treatment costs by 20–35%—here’s the quick math: fewer unnecessary surgeries and surveillance visits.
Securing private payer coverage lowers patient out-of-pocket costs, boosts test uptake (Castle reported 28% annual test volume growth in 2024), and accelerates clinician adoption.
Patient Access and Financial Assistance
Castle Biosciences runs a patient assistance program offering sliding-scale fees and payment plans for uninsured or underinsured patients and those with high deductibles, reducing cost barriers to tests like DecisionDX-Melanoma (list price ~USD 8,400 in 2024).
Value Based Pricing Models
Castle Biosciences prices its genomic tests to reflect high clinical value and lab complexity, supporting premium reimbursement; in 2024 Castle reported average revenue per test near $2,100 and molecular gross margins around 60%.
The firm argues value-based pricing reduces total care costs via fewer unnecessary treatments—studies show decision-impact rates up to 30% and potential downstream savings of $1,200–$4,500 per patient in select cohorts.
Instead of low-cost competition, Castle leans on payer contracts and cost-effectiveness data to justify price premiums versus histopathology or limited assays.
- Avg revenue/test ≈ $2,100 (2024)
- Molecular gross margin ≈ 60%
- Decision-impact up to 30%
- Estimated downstream savings $1,200–$4,500/patient
PAMA and Market Rate Adjustments
- CMS 2024 CLFS shifts ~6–9% for molecular oncology
- Castle targets gross margins ~65%+
- Pricing model updates tied to quarterly CMS data reviews
