Physician Practice Registration Checklist: NPI, CAQH, DEA, State License, and Credentialing
The administrative registration process for a new physician practice involves more moving parts than almost any other business type. You need registrations from federal agencies (CMS, DEA), state agencies (medical board, pharmacy board, business registration), and private organizations (CAQH, insurance payers) — and many of these are interdependent. Starting one application before completing a prerequisite can delay your opening by 30–90 days. This checklist puts every step in the right order so you can track progress and open on schedule.

The Quick Answer
Start this process 4–6 months before your target opening date. The longest lead-time items are insurance credentialing (60–150 days per payer via CAQH) and DEA registration (2–4 weeks, $888 fee). NPI Type 1 (your personal NPI) and NPI Type 2 (your practice entity NPI) are free and process in 1–10 business days at nppes.cms.hhs.gov. Your state medical license must be active and unrestricted before any other application can proceed. Set up your CAQH ProView profile immediately after forming your business entity — payers reference CAQH for credentialing and it's the single most time-sensitive step for an insurance-accepting practice.
Step 1 — State Medical License and Entity Formation
Before anything else: confirm your state medical license is active, in good standing, and will not expire during your first 12 months of practice. Most state medical licenses require renewal every 1–3 years and 25–50 CME hours per cycle. If your license is expiring within 6 months of your planned opening, renew it first. Next, form your business entity (PLLC or PC) with the state secretary of state. Obtain your federal EIN from the IRS (irs.gov, free, same-day via online application). Register your business name (DBA or assumed name) if your practice name differs from your legal entity name. These steps take 1–5 business days and cost $100–$500 in state fees. Without an active entity and EIN, you cannot apply for NPI Type 2, DEA, or business banking.
Step 2 — NPI Registration (Type 1 and Type 2)
National Provider Identifiers (NPIs) are your federal provider identity numbers and are required for insurance billing, DEA registration, and Medicare enrollment. NPI Type 1 is your individual physician NPI — you likely already have this from residency or a previous job. If not, apply free at nppes.cms.hhs.gov (processing: 1–10 business days). NPI Type 2 is your practice entity's NPI — required for group billing and insurance contracting. Apply online at the same NPPES portal using your EIN. You'll need your entity legal name, EIN, practice address, and taxonomy code (your specialty code — find it at nucc.org). Important: update your NPI Type 1 with your new practice address and phone number as soon as you have a confirmed office location — payer directories use NPPES data and outdated addresses cause claim rejections.
Step 3 — CAQH ProView for Insurance Credentialing
CAQH ProView (proview.caqh.org) is the centralized credentialing database used by the majority of commercial insurance companies. Instead of submitting separate credentialing applications to each payer, you complete one CAQH profile and authorize payers to access it. Your profile includes: education and training history, work history for the past 10 years, malpractice insurance documentation (COI), DEA registration, state license, board certifications, and hospital privileges (if any). Keep your CAQH profile 100% complete and authorized — payers check it quarterly, and an unauthorized profile halts credentialing. Set a quarterly calendar reminder to re-authorize your profile. Most payers require 60–120 days to complete credentialing after receiving your CAQH access — which is why you must start CAQH setup 4–6 months before your opening date.
Step 4 — DEA Registration and State Controlled Substance License
A DEA Controlled Substance Registration is required to prescribe Schedule II–V medications (opioids, benzodiazepines, stimulants). Apply at deadiversion.usdoj.gov. The registration fee is $888 for a 3-year individual registration. DEA registration requires an active state license, NPI, and a practice address. Processing time is typically 2–4 weeks; online applications are faster than paper. In addition to the federal DEA registration, most states require a separate state controlled substance registration or license — check your state pharmacy board's website. Some states (e.g., New York with iStop, California with CURES) mandate use of the state Prescription Drug Monitoring Program (PDMP) before prescribing controlled substances — register with your state's PDMP and complete any required training before writing your first Schedule II prescription.
Step 5 — Medicare and Medicaid Enrollment
Enrolling in Medicare as a participating provider allows you to bill CMS for Medicare patients. Apply through PECOS (Provider Enrollment, Chain, and Ownership System) at pecos.cms.hhs.gov — enrollment processing takes 30–90 days. You'll need: NPI Type 1 and Type 2, EIN, state license, malpractice insurance, and banking information for EFT payment setup. Medicare enrollment also gives you access to Medicare Administrative Contractor (MAC) resources and fee schedules. For Medicaid: each state has a separate Medicaid enrollment process — contact your state Medicaid agency directly. Medicaid enrollment can take 60–120 days and may require site visit verification. Important: you cannot bill Medicare or Medicaid until your enrollment is approved — do not see Medicare/Medicaid patients with the intention of billing until you have your provider number. DPC physicians who opt out of Medicare must file a formal opt-out affidavit with their MAC.

FREQUENTLY ASKED QUESTIONS
How long does insurance credentialing take?
Credentialing with commercial insurance payers takes 60–150 days on average, depending on the payer. UnitedHealthcare and Anthem tend to be faster (60–90 days); Medicaid managed care plans and smaller regional insurers can take 90–150 days. Start credentialing applications simultaneously with CAQH setup — do not wait for one payer approval before applying to the next. Practices that delay credentialing by 60 days miss 60 days of insurance revenue that can never be recovered.
Can I see patients and bill insurance before credentialing is complete?
No. You cannot bill an insurance payer until you have an approved provider contract with that payer. Billing before approval results in claim denials and potential fraud liability. However, you can see patients on a self-pay or cash basis before credentialing is complete. Some physicians open DPC or cash-pay practices during the credentialing window and then transition insurance patients once approved — a practical approach to avoid a complete income gap.
Do I need a separate DEA registration for each state I practice in?
Yes. DEA registration is state-specific — your DEA number is tied to a single registered location. If you practice in multiple states (common for telehealth) or relocate, you need a separate DEA registration per state. The DEA Diversion website allows online multi-state registration. Each state registration costs $888 for a 3-year term. Some telehealth-only states have pursued DEA registration waivers post-COVID — check the current DEA telehealth prescribing rules as of your opening date, as these regulations have been in flux.
