Medical billing transforms patient encounters into revenue through a systematic 12-step process that ensures accurate claims submission and timely reimbursements.
The 12 Core Medical Billing Steps
1. Patient Registration
Collect demographics (name, DOB, address), insurance details, and emergency contacts during initial visit or online pre-registration. Accurate data prevents 30% of claim denials upfront.curogram
2. Insurance Verification
Confirm active coverage, copay amounts, deductibles, and referral requirements before services. Real-time eligibility checks via payer portals reduce verification errors by 85%.collaboratemd
3. Clinical Encounter
Document services via superbill containing CPT procedure codes, ICD-10 diagnoses, and HCPCS supply codes from the provider-patient interaction.drcatalyst
4. Medical Coding
Professional coders translate clinical documentation into standardized codes:
- CPT: Procedures (99213 office visit, 27130 hip replacement)
- ICD-10: Diagnoses (E11.9 diabetes, J45.909 asthma)
- HCPCS: Supplies/drugs (J3420 Vitamin B12 injection)
5. Charge Entry
Enter coded charges into practice management software with correct pricing from fee schedules. Includes modifiers like -25 (significant separate service) or -59 (distinct procedure).outsourcestrategies
6. Claims Scrubbing
Automated software validates claims against payer rules, catching errors like missing modifiers or code mismatches before submission. Clean claims have 95%+ acceptance rates.curogram
7. Claim Submission
Transmit electronically via clearinghouses (e.g., Availity, Change Healthcare) using CMS-1500 (professional) or UB-04 (facility) formats. EDI 837 standard ensures HIPAA compliance.collaboratemd
8. Payer Adjudication
Insurers review claims (7-30 days), applying medical necessity, contract terms, and bundling rules. Results in payment, denial, or rejection with EOB/ERA explanation.curogram
9. Payment Posting
Apply reimbursements, contractual adjustments, and patient payments to accounts receivable. ERA auto-posting reduces manual errors by 90%.outsourcestrategies
10. Denial Management
Analyze denials by reason code (CO-97 bundled, PR-45 adjustment), appeal with medical records, or resubmit corrected claims. Recovers 10-20% lost revenue.collaboratemd
11. Patient Billing
Invoice remaining balances via clear statements showing insurance payments, adjustments, and patient responsibility. Offer payment plans for balances >$100.medicalbillingandcoding
12. Reporting & AR Analysis
Monthly reports track Days in AR (target <45), clean claim rate (>95%), and denial rates (<5%). Guides process improvements.curogram
