Medicaid billing generates the majority of revenue for many home care agencies. Here's how to do it right.

Medicaid Billing Basics

Getting Set Up

  1. Complete Medicaid provider enrollment in your state
  2. Obtain your Medicaid provider number
  3. Enroll with a Medicaid billing clearinghouse (or bill directly through your state's portal)
  4. Set up your billing software (many EMRs include Medicaid billing)

Fee-for-Service vs. Managed Care

Fee-for-Service: Bill your state Medicaid agency directly. Rates are published. Payment is predictable.

Managed Care: Contract with MCOs (managed care organizations). Each MCO may have different rates, requirements, and claim submission processes.

Common Medicaid Service Codes

Code Service Typical Rate
T1019 Personal Care Services $12–$28/hr
T1021 Home Health Aide $15–$35/hr
S9122 Home Health Aide (hourly) $15–$30/hr
S9123 Nursing care (RN, per hour) $40–$75/hr
G0151 Physical therapy services $50–$100/visit

Important: Codes and rates vary significantly by state. Check your state's Medicaid fee schedule.

Documentation Requirements

Every Medicaid claim must be supported by:

  • Service authorization — valid prior authorization on file
  • Care plan — signed by physician or authorized provider
  • Visit notes — documenting services provided, time, and client condition
  • Caregiver signature and date
  • Client/representative signature (required in many states)

Documentation Do's and Don'ts

Do: - Document in real-time or same day - Be specific about tasks performed - Note any changes in client condition - Include start and end times

Don't: - Use vague language ("provided care") - Document services not actually provided - Use the same note for every visit (copy-paste) - Backdate documentation

Claims Submission Process

  1. Verify eligibility before each service date
  2. Submit claims electronically through your clearinghouse
  3. Use correct billing codes with appropriate modifiers
  4. Meet timely filing deadlines — varies by state (90–365 days)
  5. Track submission status and follow up on pending claims

Handling Denials and Appeals

Common Denial Reasons

  • Client not eligible on date of service
  • No valid authorization
  • Duplicate claim
  • Incorrect coding
  • Missing documentation

Appeal Process

  1. Identify the denial reason from the remittance advice
  2. Correct the issue (documentation, coding, eligibility)
  3. Resubmit within your state's appeal deadline
  4. Track appeal outcomes and adjust processes to prevent recurrence

Revenue Optimization

  • Verify eligibility monthly — catch changes before they cause denials
  • Submit claims within 48 hours of service delivery
  • Audit 10% of claims before submission for accuracy
  • Follow up on unpaid claims every 14 days
  • Enroll in multiple waiver programs for diversified revenue
