NPI Registration & CAQH Profile Setup

Two free registrations unlock everything: NPI (10 minutes online) and CAQH (1–2 hours). Every insurance application starts from these two profiles. Do them first!

Everything in credentialing starts with your NPI and CAQH profile. NPI Type 1 is your individual provider identifier -apply via NPPES (cms.gov). If you have formed a practice entity, you also need an NPI Type 2 (organizational) -this determines whether claims bill under your personal ID or the group entity. Choose your taxonomy code carefully (it impacts payer routing) and keep your NPI record current; CMS requires changes reported within 30 days. Next, CAQH: the Provider Data Portal (proview.caqh.org/pr) is a centralized profile that payers pull from during credentialing -it is free and essentially mandatory if you want to be in-network. If you did not receive a CAQH welcome email, self-register by clicking "Register" on the portal. You will need your NPI, DEA number (if obtained), license number and state, SSN, and email. CAQH will email your Provider ID and a link to create your account. Usernames must be 8 characters, letters and numbers only -no special characters like @ or #. Put your CAQH credentials in a password manager immediately. The correct order for completing CAQH: fill out Profile Data first, then Review and Attest, then upload Documents, then Authorize organizations. Starting with document uploads before attesting causes rejection loops.

CAQH Deep Dive: Profile, Locations & Malpractice

Use the exact USPS-standardized address everywhere. Re-attest CAQH every 120 days (set a calendar reminder now!). These two habits alone prevent 80% of credentialing delays.

Your CAQH profile is a credentialing application, not a bio -treat every field with precision. Practice locations are the most common failure point: CAQH applies USPS address standardization and may suggest a reformatted address. When it does, adopt that exact format as your canonical address across NPPES, CAQH, payer enrollment, your website, and Google Business Profile -directory mismatches cause credentialing delays and patient confusion. Avoid PO Boxes in practice location fields (CAQH will reject them). If you are telehealth-only, use the "virtual-only location" checkbox. Creating duplicate locations (same address and Tax ID) triggers errors -keep a list of every location created. For malpractice insurance: enter your policy in Profile Data, then upload the face sheet/COI in Documents. Critical detail: the expiration date you enter must exactly match the face sheet document, or CAQH rejects the upload. If renewing an expired policy, you must click "Renew" on the expired record first, enter updated effective and expiration dates, then upload the new face sheet -uploading a renewed document without first renewing the record in the portal causes rejection. CAQH requires re-attestation every 120 days to keep your profile active. Set a recurring calendar reminder every 90 days -expired CAQH profiles disrupt credentialing and directory listings.

Payer Credentialing, Contracting & Enrollment

Start credentialing 120–180 days before opening. Focus on your top 5 payers first. A simple tracking spreadsheet + follow-ups every 2 weeks keeps everything moving.

Understand three distinct stages that happen sequentially: credentialing (payer verifies your qualifications -license, education, malpractice, background, work history), contracting (you agree to the payer's fee schedule, terms, and participation requirements), and enrollment (activating claims submission, ERA/EFT, and directory listing). CAQH supports the credentialing data portion; contracting and enrollment are direct payer processes. Build a "provider packet" even if payers have online portals: W-9 (signed), NPI confirmation (Type 1 and Type 2), license copies, malpractice COI, CV in month/year format with all gaps explained, practice address and hours, taxonomy codes, and a voided check for EFT. Authorize every target payer in your CAQH profile -if a payer cannot see your CAQH data, they treat your application as incomplete. For Medicare, enroll via PECOS (pecos.cms.hhs.gov) -CMS notes it is paperless and processes faster than paper Form 855I. Submit CMS-588 for EFT at the same time. Timeline reality check: commercial payers typically take 60-120 days; Medicare takes 30-90 days; Medicaid varies widely by state. Start credentialing 120-180 days before your target opening date. Track every application in a spreadsheet: payer, date submitted, portal/reference ID, follow-up cadence (every 7-14 days), missing items, effective date, and "live to bill" status.

Fee Schedule Development & Contract Negotiation

Set your fees at 150–250% of Medicare rates — that's standard practice, not greedy. Your top 20 CPT codes will drive 80% of your revenue. Focus your negotiation energy there.

Your fee schedule is the price list for every service you provide, expressed in CPT codes with corresponding dollar amounts. Start with the CMS Physician Fee Schedule (cms.gov/medicare/payment/physician-fee-schedule) -this shows Medicare reimbursement rates by CPT code and locality. Set your practice fees at 150-250% of Medicare rates (this is standard and ensures you never bill below what a payer would reimburse). Commercial payers reimburse at varying percentages of Medicare or their own fee schedules -typical commercial rates range from 120% to 200% of Medicare depending on your specialty, market, and negotiating leverage. When you receive payer contracts, compare offered rates against Medicare and your fee schedule for your top 20-30 most-billed CPT codes -these represent 80%+ of your revenue. Negotiate: new practices have less leverage, but you can request rate increases at contract renewal (typically annual), ask for rate parity with other local providers, and push back on unfavorable terms like all-products clauses (requiring participation in all plan products if you join one) or silent PPO provisions. Understand your state's "any willing provider" laws -some states require payers to accept any qualified provider who agrees to contract terms. Review fee schedule annually against updated Medicare rates and market benchmarks; many practices leave money on the table by never updating their charge master.

Denial Prevention, Management & Appeals

Verify eligibility before every visit and submit claims weekly. Those two habits keep denials under 5%. And always appeal — 60–70% of denied revenue is recoverable!

Denials are not a cost of doing business -they are a signal of workflow problems. The average medical practice denial rate is 5-10%, but top-performing practices achieve under 4%. Denials fall into preventable categories: eligibility/coverage denials (patient was not active or service was not covered -prevent with real-time eligibility verification before every visit), authorization denials (prior auth was required but not obtained -build auth checking into your scheduling workflow), coding denials (incorrect ICD-10/CPT pairing, unbundling errors, modifier misuse -prevent with coding education and claim scrubbing), duplicate claim denials (resubmission without proper handling -track original claim status before resubmitting), and timely filing denials (claim submitted after payer's deadline, typically 90-365 days -prevent with weekly claim submission discipline). Build a denial management workflow: (1) categorize every denial by root cause, (2) work high-dollar denials first, (3) appeal within payer timelines using the correct appeal form and supporting documentation, (4) track appeal outcomes, and (5) report denial trends monthly to identify systemic issues. Many practices never appeal denials, leaving 60-70% of recoverable revenue on the table. Automate what you can: your PM/clearinghouse should flag common rejection reasons before claims are submitted, and ERA auto-posting should route denials to a work queue rather than letting them age silently.
