How to Use This Calendar

DEA 21 CFR Part 1304 compliance is not a once-a-year event — it is a continuous, documented practice. Most enforcement actions against veterinary registrants stem not from a single catastrophic failure but from accumulated small gaps: months of inconsistent witness logs, a biennial inventory that was never completed, a reconciliation that slipped from monthly to quarterly to annual.

This calendar gives practice managers and compliance officers a month-by-month structure for staying current. Each task is prioritized by urgency:

  • Critical — missed or deferred tasks in this category create direct regulatory exposure
  • High — important for defensibility in an inspection; document completion
  • Medium — best practice; reduces risk over time
💡 VetRx Ledger users:Monthly reconciliation, blind counts, dual-witness enforcement, and biennial inventory documentation are all automated or streamlined in the platform. The calendar tasks marked as "VetRx automates" can be completed in minutes rather than hours.

January

Q1
HighComplete prior-year annual summary review

Review your Schedule II–V usage totals for the prior calendar year. Identify any drugs where consumption significantly diverged from purchase — a gap of >10% without documented explanation is a reconciliation flag. Document your review findings.

CriticalVerify DEA registration expiration date

DEA registrations expire every 3 years. Check your DEA-224 certificate for the expiration date. If it expires before October, your renewal window opens now. DEA recommends renewing 60 days before expiration.

HighUpdate controlled substance authorized handlers list

Any staff changes in the prior quarter should trigger an update to your authorized CS handlers roster. Remove departed staff from system access; add new handlers with documented training completion.

February

Q1
HighConduct Q1 blind count on Schedule II–III drugs

Blind counts (physical vault counts without reference to the running balance) serve as the primary diversion detection mechanism between month-end reconciliations. Perform at least one per quarter on Schedule II items. Document the count with two staff witnesses.

MediumCheck for DEA regulation updates

The DEA publishes regulatory changes in the Federal Register. Subscribe to the DEA Diversion Control Division newsletter or assign a staff member to check for Final Rules affecting veterinary registrants. Key items to watch: Schedule rescheduling (ketamine has been proposed for Schedule II), MATE Act compliance updates, and CSAT reporting threshold changes.

March

Q1
CriticalQ1 month-end reconciliation review

Complete full reconciliation for Q1: verify that all running balances match physical counts, all wastes have dual witnesses, all discrepancies are documented with explanations. The Q1 reconciliation should be retained for at least 2 years per 21 CFR §1304.04.

MediumSchedule annual controlled substance staff training

Most state veterinary boards and DEA consent agreements require annual CS training for all authorized handlers. Schedule Q2 training now to ensure attendance. Training topics: diversion recognition, proper waste procedures, blind count protocol, reporting obligations.

HighCheck CSAT reporting obligations (if applicable)

Veterinary practices that dispense controlled substances above certain thresholds may have ARCOS (Automation of Reports and Consolidated Orders System) reporting obligations. Confirm whether your purchase volumes trigger reporting requirements with your DEA Diversion Investigator or legal counsel.

April

Q2
HighConduct Q2 blind count

Second quarterly blind count. Focus on any drug that showed a discrepancy in Q1. Use two independent counters — one counts, one records — and do not reference the running balance until after the physical count is complete. Compare results to the balance and document.

MediumReview SOP documentation for currency

SOPs for controlled substance handling should be reviewed and re-signed annually, or whenever regulatory requirements change. Confirm that your SOP for dual-witness waste, blind counting, emergency after-hours dispensing, and drug disposal are current and staff-acknowledged.

May

Q2
CriticalBiennial inventory planning (if applicable)

The DEA requires a physical biennial inventory of all Schedule I–V controlled substances on hand every two years, on or around May 1 (the original date most DEA registrations were issued) or the specific biennial date for your registration. If your biennial date falls in H2, begin planning now: identify the count team, schedule a slow-census day, prepare inventory forms, and test your documentation system.

MediumRun staff re-acknowledgment of CS access policies

Have all authorized CS handlers sign an annual access acknowledgment that confirms they have reviewed and understood the current SOP. This creates a dated record of policy awareness that is valuable in diversion investigations.

June

Q2
HighMid-year compliance self-audit

Conduct a mid-year self-audit against the DEA's compliance checklist (or a tool like the VetRx Ledger 47-point checklist). This is not a substitute for external audit, but it identifies gaps while you still have 6 months to remediate before year-end. Common mid-year findings: expired DEA-222 order forms (obsolete in e-CSOS era but some practices still maintain), unsigned log entries, inconsistent lot/batch recording.

HighAnnual staff CS training execution

Complete and document annual controlled substance training for all handlers. Issue certificates of completion, retain in personnel files. This training record is specifically requested during DEA inspections.

CriticalQ2 reconciliation review

Complete H1 reconciliation. Review the first six months of the year as a complete unit: are purchase volumes tracking with consumption? Are all Schedule II purchases documented on DEA-222 or e-CSOS? Are there any ARCOS discrepancies requiring reporting?

July

Q3
CriticalBiennial inventory execution (if July/August anniversary)

For registrations with July/August biennial dates: conduct the required physical inventory. The inventory must capture the exact count of each Schedule I–V substance on hand on the inventory date, including partial units. Two staff members must be present. Retain the completed inventory for 2 years minimum.

HighQ3 blind count

Third quarterly blind count. If this is a biennial inventory month, the biennial inventory satisfies the blind count requirement for Q3.

August

Q3
CriticalDEA renewal check (for October/November expiration)

If your DEA registration expires in October or November, your 60-day renewal window opens now. Renew online at DEA.gov. Late renewal (within 30 days of expiration) is permitted but creates compliance gap risk. An expired registration means you cannot legally possess controlled substances — even briefly.

MediumReview drug disposal and reverse distribution procedures

Controlled substances that are expired, unusable, or in excess must be disposed of through DEA-registered reverse distributors or via authorized takeback events. Confirm that your current disposal process is documented and that disposal records are retained per DEA requirements. Improper disposal is a separate violation category with significant penalties.

September

Q3
CriticalQ3 reconciliation and year-end planning

Complete Q3 reconciliation and begin year-end planning. Identify any recurring discrepancies that need investigation before year-end. If you plan to conduct an optional annual third-party compliance audit, schedule it for Q4 now.

MediumUpdate emergency contact and registrant information with DEA

Registrant changes (ownership changes, new responsible veterinarian, address changes) require notification to DEA within 30 days. Confirm that your DEA-224 information accurately reflects current practice ownership and registrant of record. A mismatch at inspection is a citable deficiency.

October

Q4
HighQ4 blind count

Fourth quarterly blind count. Given the proximity to year-end, this count is particularly important — year-end discrepancies that aren't identified and documented now become part of your annual reconciliation problem.

MediumYear-end inventory preparation

Plan for your December 31 year-end physical inventory (if you maintain calendar-year records). Identify who will conduct the count, prepare inventory sheets, and schedule the count during a low-census period to minimize disruption.

November

Q4
HighComplete any deferred compliance remediation

If your mid-year audit or Q3 reconciliation identified gaps — unsigned log entries, missing documentation, incomplete biennial inventory paperwork — this is the last practical window to remediate before year-end.

CriticalRenew state CS permits (varies by state)

Many states require a state-level controlled substance registration separate from the federal DEA registration, often with annual renewal. Expiration dates vary by state. Confirm your state CS permits are current. Common states requiring separate permits: California, Florida, New York, Texas, Illinois. Check your state veterinary board for specific requirements.

December

Q4
CriticalYear-end physical inventory

Complete the year-end physical inventory (if calendar-year records). Count all Schedule I–V substances on hand as of December 31 (or your fiscal year-end). This inventory becomes the opening balance for the following year and the baseline for your annual reconciliation. Two-person count is required.

CriticalAnnual reconciliation sign-off

The registrant of record (owner-DVM) should review and sign the annual reconciliation. This creates an affirmative, dated compliance record. Any unexplained discrepancies should be documented with investigation notes, not left as unexplained gaps.

HighArchive prior-year records

DEA requires controlled substance records to be retained for 2 years (Schedule II) and 2 years (Schedule III–V) from the date of the activity. Confirm that records from 2 years prior are properly retained and accessible. Digital records must be readily retrievable — an auditor should not have to wait more than a few business days for records.
