Cash Per Case Down? 5 Causes Hurting ASC Revenue (And How to Fix Them)
Author:
Amanda Whitener, Sr. Director, Client Development at nimble solutions
In many conversations I have with ASCs, cash per case isn’t something they’re consistently tracking. This makes it hard to see where performance is falling short or where it could be improved.
And honestly, it’s almost never one big, obvious issue. It’s usually a handful of smaller breakdowns across the revenue cycle that, over time, start to chip away at performance.
When I dig in with clients, these are the first places I look:
1. Coding Gaps: You’re Leaving Revenue on the Table
This is almost always one of the fastest places to find opportunity.
When you take a closer look, you’ll typically find:
- Codes that were documented but never billed
- Diagnosis codes that are too generic to support medical necessity
- Cases defaulting to lower-reimbursing CPTs due to unclear documentation, without a request for doctor clarification
None of this is unusual—but it adds up quickly.
What to do:
Start with a coding audit. Even small fixes here can make an immediate impact on cash per case.
2. Contracts: You’re Not Getting Paid What You Should
Even strong operations can’t make up for weak or outdated contracts.
I often see:
- Rates that haven’t kept up with the market
- Vague or incomplete contract language
- New or growing specialties not fully accounted for
- Underpayments that aren’t being tracked or recovered
What to do:
Get down to the CPT level. Understand how each payer is reimbursing, where you’re underperforming, and whether contract terms are being applied correctly. This is one of the biggest levers to improve cash per case.
3. Lack of Visibility: You Don’t Know What Changed
Sometimes cash per case drops—and no one can clearly explain why.
That’s usually a visibility issue.
What I always look at:
- Case mix (including high vs. low acuity)
- Payer mix (especially shifts away from commercial plans)
- Specialty mix
- Trends over time
Because usually, something did change:
- A shift toward lower-reimbursing cases
- An increase in Medicare volume
- A specialty mix that’s less profitable than expected
What to do:
Build a simple monthly review process. Ask: What changed this month?
When you have that clarity, performance becomes much easier to manage.
4. A/R and Denials: The Patterns Are There—Use Them
Your A/R is telling you a story—you just have to step back and look at it.
Common patterns:
- Repeat denial reasons
- Payers consistently underpaying or delaying payment
- A/R building up in specific aging buckets
What to do:
Don’t just work A/R—analyze it. Identify patterns, find root causes, and fix the upstream issues creating rework and delays.
5. Front-End Breakdowns: It Starts Earlier Than You Think
Many revenue issues don’t start in billing—they start with the front office.
If eligibility, authorizations, or patient demographic data aren’t handled correctly, it creates downstream issues that impact reimbursement.
What to watch:
- Authorization-related denials
- Eligibility errors
- Gaps in financial clearance
What to do:
Tighten front-end workflows and focus on clean inputs—because cleaner inputs lead to cleaner claims. (As a benchmark, clean claim rates should exceed 95%, and many organizations fall short.)
The Reality
This is exactly where having the right partner makes a difference. At nimble, we don’t operate as a vendor working one part of your revenue cycle—we work alongside your team to connect all of it.
We bring together coding, managed care, front-end operations, A/R, and analytics, and align them around one goal: maximizing cash per case.
That means we’re not just identifying issues—we’re helping fix them, operationalize improvements, and drive measurable results over time.
Because at the end of the day, it’s not just about better processes, it’s about having a partner who understands the nuances of surgical revenue and knows how to turn insight into performance.
