The Billing Lifecycle

Medical billing spans registration, eligibility, coding, charge entry, claim submission, payment posting, denial management and A/R follow-up. Revenue leaks at every handoff, so each step must be tight and measurable.

Clean Claims Are Everything

First-pass acceptance is the strongest predictor of financial health. Automated scrubbing plus payer-specific edits should push your clean-claim rate above 95% before submission.

In-House vs. Outsourced

As payer complexity rises, many practices find outsourced billing delivers higher collections at lower overhead than staffing, training and retaining an in-house team.

Key takeaways

  • Map every step of your billing lifecycle
  • Target a 95%+ clean-claim rate
  • Automate claim scrubbing
  • Benchmark in-house vs. outsourced cost
