State Controlled Substance Registration (CDS / CSR)
About half the states require their own controlled substance registration in addition to the federal DEA registration, and most of them require it before the DEA will approve Form 224. We identify whether your state requires one, file it, and keep it renewed on its own cycle.

Want us to run it?
Tell us which states and how many providers; we map the requirements at no cost.
A state controlled substance registration goes by different names: CDS registration in Maryland and New Jersey, CSR in Massachusetts, controlled substance license in Michigan and Illinois, and similar terms elsewhere. Whatever the name, it is issued by a state agency, separate from the medical board, and it authorizes controlled substance activity within that state. Texas, Florida, California, New York, Georgia and Virginia do not issue one; New Jersey, Maryland, Massachusetts, Connecticut, Delaware, Illinois, Michigan and others do.
The sequencing matters. In states that require a CDS, the DEA will not issue a registration until the state one is in hand, and the state will not issue one until the license is active. ClainetRCM runs the three in order, tracks the separate renewal cycles, and updates all of them when a provider changes address.

- of states require a CDS or CSR
- Before DEA
- in most of those states
- Separate cycle
- from the license and DEA
Where this usually goes wrong
Not knowing the state requires one
Providers who move from a state without a CDS to one that has it apply to the DEA, get rejected, and only then discover the state step.
Renewal cycles out of step
A license may renew every two years, a CDS every year or every three, and the DEA every three. Tracked separately, one of them is missed.
Prescribing authority limits
Some states restrict the schedules a nurse practitioner or physician assistant may prescribe, and the CDS application must match those limits or it is returned.
What ClainetRCM handles
One coordinator owns the file from intake to effective date, so you always know who to call and what is outstanding.
- State-by-state determination of whether a CDS or CSR is required for each provider and location
- CDS application prepared and filed with the correct state agency
- Sequencing so the license, CDS and DEA are issued in the right order
- Schedule selection matched to the provider's state prescriptive authority
- Renewals on each state's cycle, filed before expiration
- PDMP enrollment where the state requires it as a condition of registration

How the work runs
Boards move on their own timeline; what we control is a complete application on day one and a verification chase that never goes quiet.
- 1
Provider review and pathway
Education, training, exams, work history and existing licenses are collected and compared with what the target board requires. We choose the fastest eligible route.
- 2
Application prepared and filed
The board application is completed, fees paid, and fingerprinting, jurisprudence exams and mandated coursework scheduled.
- 3
Verifications chased
Schools, training programs, exam authorities and prior boards are asked for verification and followed up weekly until every one arrives.
- 4
License issued
Deficiency requests are answered the same business day; the license number is delivered to your credentialing file the day it posts.
- 5
Registrations and renewal calendar
State CDS, DEA and PDMP registrations are filed in order, and every expiration date and CME rule goes on one monitored calendar.
Frequently asked questions
No. The DEA registration is federal and required everywhere. A CDS or CSR is a separate state registration that only some states require, and in most of those states it must be obtained before the DEA registration.
It changes as states amend their laws. New Jersey, Maryland, Massachusetts, Connecticut, Delaware, Illinois and Michigan are among the states that require one; Texas, Florida, California and New York do not. We verify the current requirement for each state at intake rather than relying on a list.
Most states issue it in two to six weeks after a complete application. Because the DEA application waits on it, we file the CDS the day the state license is issued.
In states that require one, yes, if they prescribe controlled substances. The application must match the schedules their state prescriptive authority allows. See nurse practitioner licensing.
