Cardiology Claim Denials in 2026
Hi, I am Derick Perkins, Chief Strategy Officer at GoSource.
I have spent 26 years in healthcare billing and operations, and if there’s one thing I can tell you with certainty, it is this:
Cardiology claim denials in 2026 are not business as usual.
If you’re leading or managing a cardiology practice, chances are you’re feeling it already slower payments, more denials, more rework, and more pressure on your team. Let’s talk about why this is happening and, more importantly, how you can fight back.
What I’m Seeing Across Cardiology Practices
In 2026, claim denials aren’t an occasional hiccup anymore. They’ve become a routine disruption to cash flow even for well-run practices with experienced billing teams.
What surprises many leaders is this:
Clean claims are still getting denied.
Not because care wasn’t appropriate.
Not because teams aren’t working hard.
But because the rules have changed and the margin for error is basically gone.
The Core Problem (It’s Simple, But Serious)
Cardiology billing has entered a new era.
Payers now expect:
- Perfect documentation
- Exact coding
- Flawless modifier usage
- Timely submissions every single time
There’s very little tolerance for “close enough.” Even small missteps can lead to denials, delays, or secondary reviews that tie up your revenue for weeks or months.
Why Cardiology Claim Denials Are Rising in 2026
Let me break down the biggest drivers I’m seeing.
- Stricter Payer Audits
Cardiology procedures are among the highest cost services in healthcare, so payers are watching them closely.
They are no longer just asking, “Was the service performed?”
They’re asking, “Was it documented, coded, and justified exactly the way we expect?”
Cath procedures, imaging, stress tests, interventional work everything is under a microscope.
- Constant Changes to CPT and Coding Rules
Cardiology coding changes fast. What worked last year may now require:
- Different modifiers
- More detailed documentation
- Stronger medical necessity support
Even unintentional use of outdated coding can push an otherwise valid claim straight into denial.
- Tiny Documentation Gaps = Big Consequences
Payers now demand procedure-level precision.
A vague note.
An incomplete diagnosis link.
A weak medical necessity statement.
Any one of these can trigger an immediate denial even when patient care was absolutely appropriate.
In 2026, documentation accuracy matters just as much as clinical quality.
- Modifier Errors (Still a Major Pain Point)
Incorrect, missing, or overused modifiers remain one of the top denial drivers in cardiology.
With more bundled and conditionally paid services, modifier accuracy is non-negotiable.
One small mistake can sink an otherwise perfect claim.
- Delayed Claim Submissions
Timing matters more than ever.
Late submissions are often denied automatically, with little or no room for appeal.
Internal delays, backlogs, or repeated corrections can turn billable work into permanent revenue loss.
The Real Cost of Denials (Beyond the Dollars)
Denials don’t just slow payments they create a ripple effect across your entire practice:
- Higher AR days
- Staff burnout from constant rework
- Lost revenue from unrecoverable claims
- Cash flow instability
- Less time and energy for patient care and growth
Without a proactive plan, denial management becomes reactive, exhausting, and expensive.
