Cardiology medical billing
The full cycle from charge entry through resolved payment, including eligibility checks and prior-authorization work that carries more weight where a patient's specific plan sets the rules.
Cardiology Revenue Cycle Hawaiʻi
In Hawaiʻi, you don't bill insurance. You bill a plan.
Two structural facts shape almost every cardiology claim in the state: Medicaid runs through five managed-care plans, and Medicare runs through Noridian. We build both into every claim we touch down to the local coverage rule and the technical/professional split.

Why specialized billing
Cardiology stacks services. Hawaiʻi stacks payers.
Cardiology billing is unusually unforgiving because so many services layer on top of each other. An echocardiogram or nuclear stress test often carries a technical and a professional component that may bill separately depending on who owns the equipment and who reads the study. Diagnostic catheterization, electrophysiology studies, and device implants carry global periods and bundling edits a generalist coder can miss and once you add a second procedure in the same session, modifier selection stops being optional.
Here that complexity compounds, because a practice isn't reconciling one dominant rulebook. It works across Medicaid managed care spread over five plans, Medicare Advantage plans that have long enrolled a large share of eligible residents, traditional Medicare through Noridian, and commercial coverage concentrated in HMSA. Treat all of that as one generic "insurance" bucket and you lose clean claims to avoidable technicalities the wrong authorization pathway, or a technical-component modifier one plan processes differently than Medicare does.
What we do
Cardiology billing & coding, end to end
Our core services work the same everywhere we operate the plan- and contractor-specific detail is built into how each one runs in Hawaiʻi.
02 · CODING
Cardiology coding
CPT, ICD-10-CM, and HCPCS built around medical necessity and modifier accuracy including the technical and professional splits common in cardiac imaging and testing.
03 · CLAIMS
Submission & scrubbing
Claims are prepared, scrubbed, and filed electronically, then tracked so a rejection from a specific QI plan or from Noridian gets fixed before it becomes a denial.
04 · APPEALS
Denial management
Denied claims are traced back to a root cause authorization, documentation, or coding corrected, and appealed where the record supports reconsideration.
05 · POSTING
Payment & reconciliation
Payments are posted and reconciled against contracted rates, so underpayments from any single plan don't quietly go unnoticed.
06 · RCM
Revenue cycle management
The whole process is tied together as one accountable cycle instead of a series of separate handoffs between disconnected steps.
State-specific payer & reimbursement
Built for Hawaiʻi's payer map
Several parts of this environment are specific enough that they'd need to be rewritten entirely for a page about Ohio or Arizona.
MedicaidManaged care
Med-QUEST runs through five plans, not fee-for-service
Med-QUEST is administered by the Hawaiʻi Department of Human Services, and effectively all beneficiaries are enrolled in QUEST Integration. Reimbursement depends on which plan the patient currently carries each contracts and pays independently, and credentialing has to happen at the plan level in addition to state Medicaid enrollment.

MedicareNoridian J-E
Traditional Medicare runs through Noridian
Noridian Healthcare Solutions administers Part A and B for Jurisdiction E, grouping Hawaiʻi with California, Nevada, Guam, American Samoa, and the Northern Mariana Islands not with any other single state. Local coverage determinations, enrollment, and appeals for traditional Medicare all run through Noridian.
Durable medical equipment relevant to ambulatory cardiac monitors and remote-monitoring hardware falls under a separate Noridian jurisdiction covering more of the western states.
CommercialHMSA-heavy
Commercial coverage is concentrated in HMSA
Hawaiʻi's Prepaid Health Care Act, in effect since 1974, requires most employers to offer coverage to employees working as few as 20 hours a week well below the ACA's 30-hour threshold. That has kept employer-sponsored coverage unusually widespread, and HMSA, the state's Blue Cross Blue Shield licensee, covers more than half of residents.
HMSA's coverage policy and prior-authorization rules for advanced cardiac imaging and procedures touch a larger share of a typical practice's commercial claims here than any single carrier tends to elsewhere.
DevelopingMarket shift
An HMSA affiliation worth tracking
HMSA and Hawaiʻi Pacific Health announced a proposed affiliation in January 2026 that would align the state's largest insurer more closely with one of its largest hospital systems. As of mid-2026 the proposal remains under legislative and regulatory review, with competing systems raising concerns about referral patterns and competition.
Independent cardiology practices should treat this as developing rather than settled: any change to how HMSA contracts and refers could affect network participation and payer negotiations.
// Requirements tied to any of this can change and usually depend on the individual plan, not the payer type alone verify current policy directly with the plan before assuming how a service will be handled.
Where claims break
Common cardiology billing problems in Hawaiʻi
Some denial patterns show up everywhere a missing modifier on a same-day procedure, thin documentation of medical necessity on a repeat stress test, an eligibility check skipped before a scheduled catheterization. Hawaiʻi adds a few of its own on top of those.
Plan-switching & stale authorizations
An authorization approved by one QI plan doesn't carry over if a patient switches plans at open enrollment, and each plan can set its own frequency limits on recurring services like Holter monitoring or follow-up echocardiography. Miss the switch and you file under a stale auth.
Neighbor-island referrals
Catheterization, EP, and cardiothoracic surgery capacity is concentrated in Honolulu, so neighbor-island patients are frequently transferred and professional and facility charges can originate from two locations for one episode. Place-of-service coding and transfer documentation matter more here.
Telehealth documentation
Telehealth follow-up for heart failure or post-procedure recovery must satisfy Hawaiʻi's own documentation standard under state law not only a payer's telehealth policy. A note that doesn't reflect adequate history and symptom review can undercut both the record and the claim.
How the cycle runs
Our cardiology revenue cycle workflow
The workflow isn't unique to Hawaiʻi but several stages carry state-specific decision points.
01
Eligibility & verification
Confirm not just Medicaid or Medicare, but which QI or Medicare Advantage plan is active that determines the authorization pathway.
02
Charge capture & coding
Apply cardiology-specific logic technical/professional splits, modifier use, medical-necessity documentation before a claim goes out.
03
Routing & submission
Claims route electronically to the correct plan or to Noridian by payer type, with status monitored so rejections are caught early.
04
Payment & reconciliation
What's received is reconciled against contracted rates, so underpayments don't sit unnoticed on any single plan.
05
Denial analysis & appeals
Denials are traced to their cause authorization, documentation, or coding and reconsideration is pursued where the claim supports it.
06
Reporting
Reporting gives visibility into how claims perform plan by plan which matters far more here than in a single-payer market.

Case mix worth coding for
Heart failure is a Hawaiʻi story, not a footnote
A 2025 study using Kaiser Permanente Hawaiʻi and Northern California patient data found meaningfully higher rates of incident heart failure among Native Hawaiian and Pacific Islander patients than other groups consistent with well-documented higher rates of hypertension, diabetes, and obesity in this population. AlohaCare, one of the state's QI plans, has already launched a remote-monitoring program specifically for members with heart failure.
For a practice managing that mix, accurate coding for chronic care management and remote monitoring isn't a minor add-on it reflects the case load many Hawaiʻi cardiology practices already carry.

Losing claims between Noridian and a QI plan?
If your practice is losing time to Medicaid plan-switching, prior-authorization delays that differ by payer, or claims that seem to vanish somewhere between contractors that's exactly the kind of problem a cardiology-only billing team is built to sort through.
We're not opening an office in Honolulu our team supports Hawaiʻi practices as part of a nationwide operation built around a single specialty.
