Added $1.2M in revenue
without seeing more patients
A cardiology practice with a full patient schedule was collecting far less than it had earned. Revenue was leaking across billing, authorizations, and AR, silently. Zen found it and fixed it.

The problem
Full schedule. Revenue that didn't match.
Every appointment slot was filled. The physicians were working at capacity. But when collections came in, the numbers told a completely different story, cash flow was weak, AR was aging, and profitability was declining despite a full book of patients.
The revenue was always there. It was just leaking out faster than it was coming in, through uncollected authorizations, aging denials, documentation gaps, and billing workflow breakdowns no one had time to fix.
✖
Eligibility gaps before every visit
Insurance eligibility wasn't being verified consistently. Claims went out on lapsed coverage and were denied at scale.
🗒
Prior authorizations lapsing silently
Cardiology procedures are high-value and require prior auth. Expired or missing authorizations were denying entire claims worth thousands each.
⚒
AR aging without follow-up
Unpaid claims were sitting in AR for 90+ days with no structured follow-up process. Denials were written off rather than appealed.
Zen's approach
Fix the systems losing revenue, not the schedule.
1
Tightened insurance eligibility verification
Every patient verified before every visit. Lapsed coverage caught before claims are submitted, stopping the single most avoidable denial category at the source.
2
Rebuilt prior authorization systems
Implemented proactive auth tracking with expiration alerts. High-value cardiology procedures now go to payers with authorization in place, every time.
3
Built structured AR follow-up processes
Created a tiered follow-up cadence, claims followed up at 15, 30, and 45 days. No claim left unworked. Denials appealed before filing windows close.
4
Reduced documentation delays impacting billing
Identified and eliminated the workflow gaps causing documentation to lag behind billing, so claims go out on time with the records that support them.
5
Identified and eliminated recurring denial causes
Tracked denial patterns by payer and code. Fixed the upstream issues causing the same denials repeatedly, so revenue recovered once stayed recovered.
The result
$1.2M more per year. Same workload.

Why it worked
The schedule was never the problem
Cardiology practices are among the most audit-prone in medicine, high claim values attract payer scrutiny. The gap between earned revenue and collected revenue grows quietly until someone audits it. Zen did.
✔
Eligibility is the first line of defence
Verifying coverage before every visit is the simplest intervention in billing, and the most neglected. It stopped the most common denial category before claims were even submitted.
✔
AR without follow-up is a gift to payers
Payers count on practices not following up. A structured 15-30-45 day cadence recovered claims that would otherwise have been written off quietly as the filing window closed.
✔
Authorization gaps are expensive in cardiology
A denied cardiology claim isn't a $50 loss, it's a $2,000–$15,000 write-off. Getting authorization right before every high-value procedure was where the largest single revenue recovery happened.
✔
Pattern-fixing compounds over time
Fixing a denial once recovers one claim. Identifying why it keeps happening and eliminating the root cause recovers that revenue across every future claim, permanently.
