The 10 most common denial codes and what each one actually means
A denial code is a diagnosis, not a verdict. Here is what the ten you will see most often are really telling you, and what the fix is for each.
Revenue cycle management for independent practices
Get paid for the work you've already done
Independent practices lose 10–15% of earned revenue to denied claims, ageing A/R, and undercoding. MedBil runs your billing end-to-end — eligibility through appeals — so that money reaches your account instead of expiring.
Month-to-month. No setup fee. No long-term contract.

The problem
Most practices don't know how much they're losing
Billing failure is quiet. There's no alert when a claim is denied and never appealed, or when a balance crosses 120 days and becomes uncollectible. The revenue simply doesn't arrive, and by the time anyone notices, the window to fix it has closed.
Denials that nobody works
A denied claim is not a lost claim — but only if someone appeals it inside the payer's filing window. Most practices don't have the hours.
Money that ages out
A claim under 30 days old collects at over 95%. Past 120 days, that falls below 30%. Time is the single biggest variable in whether you get paid.
Coding left on the table
Practices routinely bill a level below what documentation supports, out of audit anxiety. That gap compounds across every encounter, every day.
No visibility
If you can't state your denial rate, your days in A/R, and your net collection rate right now, you can't manage them.
The collection-probability and A/R figures above are industry benchmarks and carry an MGMA/HFMA citation wherever they are published as claims about MedBil results.

The process
What actually happens to a claim
Nine steps, every claim, every time.
- 1 Eligibility and benefits Verify active coverage, deductible status, copay, and plan limitations before the encounter.
- 2 Prior authorisation Identify what needs auth, submit it, track it, and escalate when payers stall.
- 3 Charge capture and coding Certified coders review documentation and assign ICD-10, CPT, HCPCS, and modifiers.
- 4 Claim scrubbing Run NCCI edits, MUE checks, and payer-specific rules before submission.
- 5 Submission Electronic submission via clearinghouse, with paper claims where a payer still requires them.
- 6 Payment posting ERAs and EOBs posted against expected reimbursement, with underpayments flagged.
- 7 Denial management Every denial is coded to a root cause, corrected, and appealed inside the filing deadline.
- 8 A/R follow-up Systematic follow-up by ageing bucket, prioritised by collectability and deadline.
- 9 Reporting Weekly and monthly reporting on denial rate, A/R ageing, net collection rate, and cost to collect.
Specialties
We bill for your specialty, not a generic version of it
Cardiology denials don't look like behavioural health denials. Modifier rules, global periods, prior-auth burden, and payer behaviour all change by specialty. Our coders are assigned by specialty, not pooled.
Behavioral Health
Time-based codes, session limits, auth burden, parity rules
Cardiology
Diagnostic testing, device codes, global periods, bundling
Orthopedics
Surgical global periods, DME, modifier 59/XU, heavy auth
Primary Care
E/M levels, preventive vs. problem visits, chronic care management
Internal Medicine

How much does medical billing outsourcing cost?
Most billing companies charge 4–9% of collections. MedBil's rates are published on our pricing page and depend on your specialty and volume.
Do I have to change my EHR or practice management system?
No. We work inside whatever system you already use. [CLIENT INPUT — list supported systems]
How long does onboarding take?
Typically [CLIENT INPUT]. We run in parallel with your existing process for the first two weeks so nothing is dropped.
What happens to my existing A/R?
We can work it alongside new claims. Aged receivables are often the fastest return on the engagement. See A/R recovery.
Am I locked into a contract?
No. MedBil works month-to-month with 30 days' notice.
Is my patient data safe?
Yes. We sign a Business Associate Agreement before touching any data, use encrypted transfer, and restrict access by role. Details on our HIPAA compliance page.
