Compliance Tools & Calculators

Free, browser-based calculators for diversion prevention and regulatory compliance. All calculations happen in your browser — no data is sent to a server.

Educational use only. These tools are for guidance and education — not legal determinations. Consult your compliance team, legal counsel, or DEA diversion investigator for case-specific decisions.

DivertGuard's compliance tools are free, browser-based calculators built for diversion program managers, pharmacy compliance officers, and nursing supervisors who need quick, reliable answers to regulatory and surveillance questions — without logging in, installing software, or transmitting data to a server.

The DEA 106 Deadline Calculator removes the guesswork from mandatory theft and loss reporting, computing both the one-business-day preliminary notification window and the 45-calendar-day Form 106 filing deadline from a single discovery date. The Controlled Substance Discrepancy Calculator quantifies count variances and flags whether a shortage meets the significant-loss threshold under 21 C.F.R. §1301.74(c). The Waste Percentage Calculator benchmarks a provider's waste ratio — one of the most consistent early signals of diversion in anesthesia and high-volume clinical units. The Biennial Inventory Due-Date Calculator tracks the two-year controlled substance inventory cycle required under 21 C.F.R. §1304.11(c). The Fentanyl Patch Reconciliation Calculator closes a common accountability gap by reconciling dispensed, administered, wasted, and returned patches in a single step.

Use these tools alongside the program assessment checklist and unit risk assessment for a structured, evidence-based approach to diversion prevention.

DEA 106 Deadline Calculator

Calculates the one-business-day preliminary notification deadline and the 45-calendar-day DEA Form 106 filing deadline from your discovery date.

Controlled Substance Discrepancy Calculator

Quantifies a count discrepancy and flags whether it may meet the threshold for a significant loss under 21 C.F.R. §1301.74(c).

Waste Percentage Calculator

Monitors a provider's waste ratio — a key anesthesia and OR surveillance metric for detecting potential diversion patterns.

Biennial Inventory Due-Date Calculator

Calculates when your next DEA biennial controlled substance inventory is due and how many days remain (21 C.F.R. §1304.11(c)).

Fentanyl Patch Count Reconciliation Calculator

Reconciles dispensed vs. administered vs. wasted vs. returned fentanyl patches — a core diversion control for high-risk transdermal opioids.

Frequently Asked Questions

The DivertGuard checklist is a weighted, interactive self-assessment that walks diversion program managers through the core elements of a defensible controlled substance program — governance, lifecycle accountability, surveillance, security controls, and incident response. It supports hospital, community pharmacy, and multi-site health system settings and generates a real-time percentage score that reveals gaps and guides remediation priorities.

No software, account, or login is required. Every calculator runs entirely in your browser using standard JavaScript. No data is sent to a server, stored in the cloud, or shared with any third party. Your inputs exist only in your current browser session.

These tools process only the numeric values you enter and perform calculations locally in your browser, so no protected health information is collected or transmitted. As a best practice, avoid entering patient names, medical record numbers, or other identifiers into any field. The tools are designed for aggregate program-level analysis, not individual patient records.

These tools are designed for internal compliance work and program improvement — not as substitutes for formal DEA record-keeping or audit documentation. Results can support your preparation and help identify areas to address before an inspection. DEA inspections require original records and logs maintained under 21 C.F.R. §1304. Consult your DEA diversion investigator or compliance counsel for case-specific guidance.

The unit risk assessment is built for diversion program managers and pharmacy compliance officers who oversee multiple clinical areas. It provides unit-level vulnerability profiles for the ED, ICU, OR, Med-Surg, Oncology, and Pharmacy — helping you direct monitoring resources where diversion risk is highest. Nursing managers and department directors can also use it to understand surveillance expectations for their care area.
