Most practices run this decision backwards. They start collecting vendor names, sit through four sales calls, compare percentage rates, and pick whoever sounded most confident. Six months later, the denial rate has not moved, because nobody established what was actually broken before shopping for a fix.
Cardiology makes this more expensive than it would be in other specialties. The code set is dense, prior authorization applies to a large share of high-value procedures, and component modifier decisions on cardiac imaging can cost most of the payment for a study. A vendor mismatch here compounds quickly.
This guide lays out a selection process that starts with your own numbers, moves through the questions that separate real cardiology expertise from a polished deck, and ends with a transition plan that does not stall collections.
Step 1: Diagnose the Problem Before You Shop
Practices rarely have one problem. They have a dominant one, and different dominant problems point toward different kinds of partners.
| What You Are Seeing | Likely Root Cause | What That Suggests |
|---|---|---|
| High denial volume, claims going out fine | Coding accuracy or payer rule currency | A partner with cardiology depth and root-cause denial reporting |
| Claims sitting unbilled for days | Charge capture or staffing capacity | A partner with throughput and defined turnaround commitments |
| Days in AR climbing steadily | Weak follow-up on aged claims | A partner with dedicated AR recovery, not just claim submission |
| Procedures denied for authorization | Prior authorization workflow gaps | A partner handling prior auth in-house with defined coverage hours |
| New providers unable to bill | Credentialing and enrollment backlog | A partner with credentialing as a real service line |
| Nobody can explain the numbers | Reporting and visibility | A partner with denial-reason reporting, not denial counts |
Write down which row describes your practice before the first sales call. It changes which questions matter and which answers should disqualify a vendor.

Step 2: Baseline Your Numbers
You cannot measure improvement against a number you never recorded. Pull these before any transition begins.
- Clean claim rate, meaning claims accepted on first submission without edits
- Denial rate, and the top five denial reasons by volume and by dollar
- Days in accounts receivable, plus the percentage of AR over ninety days
- Net collection rate against contracted allowables
- First-pass resolution rate
- Average days from date of service to claim submission
General benchmarks worth knowing: a clean claim rate in the mid-nineties is healthy, days in AR under forty is reasonable and under thirty is strong, and net collection rate should sit in the mid-nineties. Cardiology practices frequently run worse than these figures, with denial rates well into double digits and AR stretching past sixty days, which is often what prompts the search in the first place.
Keep this baseline. It becomes the only objective way to evaluate the new arrangement in six months.
Step 3: Build a Shortlist That Matches Your Profile
Shortlist criteria that actually predict fit:
- Specialty depth in cardiology specifically, including interventional and electrophysiology if you perform those services
- Experience with your payer mix, including your Medicare contractor’s jurisdiction and your state Medicaid program if relevant
- Scale appropriate to your volume, since a firm built for hospital systems and a firm built for solo practices operate differently
- Staffing model, whether onshore, offshore, or hybrid, and how each function is allocated
- Scope, meaning whether credentialing, prior authorization, and patient billing are included or priced separately
- Integration with your existing systems rather than a required platform migration
Three to four serious candidates is enough. Beyond that, evaluation quality drops faster than optionality improves.
Step 4: Ask the Questions That Separate Expertise From a Sales Deck
This is where most evaluations go soft. General questions produce general answers. Cardiology-specific questions produce clarity fast.
Specialty questions worth asking:
- How do you handle the professional and technical component decision when our physicians read studies performed on hospital equipment?
- Which cardiac services in our mix require prior authorization with our top payers, and who on your team handles those requests?
- How do you stay current with our Medicare contractor’s local coverage determinations?
- How did you handle the 2026 cardiovascular code changes for your existing cardiology clients?
- What are the three most common denial reasons you see in cardiology, and how do you prevent them?
Operational questions worth asking:
- Who specifically works our account, and what happens when that person is unavailable?
- What is your escalation path when a claim needs urgent attention?
- What hours is your team reachable, and in which time zone?
- What is your average turnaround from charge receipt to claim submission?
Reporting questions worth asking:
- Can we see a sample monthly report from a cardiology client, with identifying details removed?
- Does your reporting show denial reasons and root causes, or only denial counts?
- How often do we meet to review performance, and who attends?
A vendor who answers the specialty questions with generalities is telling you something useful.
Step 5: Compare Pricing Models Honestly
The headline percentage is the least informative part of a pricing conversation.
| Model | How It Works | What It Incentivizes | Fits Best When |
|---|---|---|---|
| Percentage of collections | Fee is a share of what is actually collected | Aligned interest in collecting, including aged AR | Most practices, especially with variable volume |
| Flat monthly fee | Fixed amount regardless of collections | Predictable cost, weaker incentive on difficult claims | Stable, predictable claim volume |
| Per claim fee | Fixed amount per claim submitted | Volume of submissions, not necessarily collections | High volume, low complexity mixes |
| Hybrid | Base fee plus a smaller percentage | Balance of predictability and alignment | Larger groups wanting cost certainty |
Percentage pricing in cardiology commonly lands in a range of roughly four to eight percent depending on volume, complexity, and scope. A lower percentage is not automatically better value. If denial management is weak, the revenue lost to unworked denials will exceed the fee difference comfortably.
Ask what is excluded. Credentialing is frequently priced separately, often per payer. Patient statements, appeals beyond a certain level, old AR cleanup, and setup work may all carry additional cost. Get the full picture in writing before comparing anything.
Step 6: Read the Contract Terms That Actually Bite
Most billing agreements read fine until you want to leave. Terms worth negotiating before signing:
- Contract term and renewal, including whether renewal is automatic and what notice period applies
- Termination rights, including whether you can exit for cause and what constitutes cause
- Data ownership, confirming that your patient and financial data remains yours
- Data export, specifically the format, timeline, and cost of receiving your data if you leave
- Transition-out obligations, meaning what the vendor must do to hand off open AR
- Performance commitments, and what happens if they are not met
- Scope definition, so that routine work does not later become a billable add-on
- Business associate agreement and security documentation
The data export and transition-out terms matter more than practices expect. A vendor that makes leaving difficult has reduced your leverage for the entire relationship.
Step 7: Plan the Transition Before Go-Live
Transitions stall collections when they are improvised. A realistic plan covers:
- A defined go-live date with a cutoff for which claims belong to which party
- A decision on old accounts receivable, whether the outgoing vendor works it to completion or the new partner takes it over
- Credentialing continuity, confirming no payer enrollment lapses during the handoff
- System access and integration testing before, not after, go-live
- A parallel period where both teams are engaged, if the volume justifies it
- Staff training on any new front-end workflows the partner requires
- A named point of contact on both sides for the transition itself
Expect thirty to ninety days depending on practice size and payer count. Practices that compress this timeline usually pay for it in a cash flow dip during the changeover.
Step 8: Set Checkpoints After Go-Live
Evaluate against the baseline from Step 2, not against impressions.
- At thirty days: are claims going out on schedule, and is the submission lag stable or improving?
- At sixty days: is the denial rate moving, and are denial reasons being reported with root causes?
- At ninety days: how do days in AR, clean claim rate, and net collection rate compare to baseline?
- At six months: has the AR over ninety days percentage improved, and is aged AR being worked?
Schedule these reviews when you sign, not when you start worrying. A partner confident in their work will welcome the structure.

Red Flags During Evaluation
- Reluctance to provide references from cardiology practices of similar size
- Reporting samples that show counts without reasons
- Guarantees of specific collection percentages, which no billing company can responsibly promise
- Vague answers on who handles prior authorization
- Pricing that is not disclosed clearly in writing before signing
- Pressure to sign quickly, or discounts that expire during the evaluation window
- Unwillingness to discuss what happens if the relationship ends
Common Pitfalls in Choosing a Billing Partner
At Zee Medical Billing LLC, we often see the same patterns when cardiology practices bring us their claim history after a difficult vendor relationship:
- Selecting on price alone, then losing more to unworked denials than the fee difference saved
- Never establishing a baseline, so improvement becomes a matter of opinion
- Assuming a local address implies knowledge of local payer rules
- Not confirming who handles prior authorization, or during what hours
- Skipping the data export and transition-out conversation until after signing
- Accepting denial counts as reporting instead of denial reasons and causes
- Compressing the transition timeline and absorbing an avoidable cash flow gap
- Never revisiting the arrangement, so a fit that worked three years ago quietly stops working
Most of these are avoidable during evaluation and expensive afterward.
FAQs
How long does it take to switch cardiology billing companies?
Most transitions run thirty to ninety days depending on practice size, provider count, and payer mix. The timeline covers system access and integration testing, payer enrollment verification, staff training on any new front-end workflows, and a defined cutoff separating old claims from new ones. Practices that compress this schedule commonly experience a temporary cash flow dip. Building the timeline into the agreement, with a named transition contact on both sides, prevents most of the disruption.
What questions should I ask a cardiology billing company before signing?
Ask specialty questions rather than general ones. How do they handle professional and technical component decisions on cardiac imaging? Which of your services require prior authorization with your top payers, and who processes those requests? How do they track your Medicare contractor’s local coverage determinations? How did they manage the recent cardiovascular code changes for existing clients? Then ask operational questions about who works your account, escalation paths, turnaround times, and whether reporting shows denial reasons or only counts.
What happens to my old accounts receivable when I switch billing companies?
This has to be decided explicitly, because defaults vary. Common arrangements include the outgoing vendor working existing AR to completion for a defined period, the new partner taking over the full AR book, or a split where older claims stay with the previous vendor while newer ones transfer. Each arrangement has cost and recovery implications. Leaving it unresolved is how aged claims fall between two teams and quietly age past timely filing limits.
What contract terms matter most with a billing company?
Data ownership and export terms matter more than most practices expect, since a vendor that makes leaving difficult reduces your leverage throughout the relationship. Also review contract term and renewal mechanics, termination rights and what counts as cause, transition-out obligations for open AR, scope definition so routine work does not become a billable add-on, and any performance commitments along with remedies if they are missed. Confirm the business associate agreement and security documentation as a baseline.
How do I know if my cardiology billing company is performing well?
Compare current numbers against the baseline you recorded before the transition. Track clean claim rate, denial rate with reasons, days in accounts receivable, percentage of AR over ninety days, and net collection rate. Improvement should be visible within ninety days in submission timeliness and denial rate, with AR metrics following over the next several months. If reporting is vague or hard to obtain, that itself is a performance signal worth addressing directly.
Conclusion
Choosing a cardiology billing company works best as a structured process rather than a comparison of sales calls. Diagnose the dominant problem, record the numbers, shortlist for fit rather than reputation, ask questions specific enough that generalists cannot answer them, and settle the contract and transition terms before signing rather than after.
Key takeaways:
- Identify what is actually broken before evaluating vendors.
- Record baseline metrics, because improvement cannot be measured without them.
- Ask cardiology-specific questions that a general biller cannot answer convincingly.
- Compare pricing models and exclusions, not just headline percentages.
- Negotiate data ownership, export, and transition-out terms before signing.
- Plan thirty to ninety days for transition and decide who works old AR.
- Schedule performance checkpoints at signing, not after problems appear.
The practices that get this right usually spend more time on evaluation and far less time repeating the process eighteen months later.
