How to reduce medical claim denials

Start with your own data, not a checklist

Generic denial-reduction advice is generic because every practice is different. Your top denial category is probably not the same as the practice next door, and effort spent on categories you do not have is wasted.

Pull three months of denials and group them by cause first. Root cause analysis covers how. Then work the list below in the order your own data dictates.

The interventions, by typical return

1. Verify eligibility before the visit

Eligibility denials are the largest preventable category in most practices and the cheapest to eliminate, because the check happens before the service rather than through an appeal afterwards. Verify at scheduling and again at check-in for anything more than a few days out.

2. Confirm authorisation before the service

Maintain a list of procedures requiring prior authorisation by payer, and make the check a step somebody owns rather than something everybody assumes. An authorisation obtained after the service is usually worth nothing.

3. Fix the specific coding issues you actually have

Not coding in general — the two or three codes or modifiers that generate most of your coding denials. A targeted audit of those is worth more than broad coding training.

4. Close the documentation gap

Where medical necessity denials recur, show the providers the denied claims and the payer policy. Specific examples change behaviour; general reminders do not.

5. Submit faster

Shorter submission lag removes timely filing denials entirely and reduces coordination-of-benefits problems. One to two business days from complete documentation is a reasonable target.

What not to bother with

• Chasing a target denial rate. There is no reliable universal benchmark, and the figures circulating are mostly unsourced. Track your own trend instead.
• Appealing everything. Some denials are correct. Time spent appealing those is time not spent on the ones with a case.
• Broad coding training when three codes cause most of your problem. Target it.
• Scrubber rules nobody reviews. Claim scrubbing helps, but rules go stale as payer policy changes and then silently stop catching things.

Who should be doing this

Prevention spans departments: front desk for eligibility, clinical for documentation, billing for coding and submission. That is exactly why it often gets done by nobody — it is no single department's job.

Whoever handles your billing should be telling you which category dominates each quarter, because they are the only ones who can see it. If they are not, see what they should be doing.
