Explore the Wider Healthcare Practice

A billing engine connects to the systems around it, so these related services cover the platforms your revenue cycle depends on.

“Hospitals and health systems spent an estimated $19.7 billion in one year trying to overturn denied claims.” — American Hospital Association

Most of those denials are avoidable, so billing software that verifies eligibility and scrubs claims before submission stops the rework that drains the healthcare industry.
Market Context

Types of Medical Billing Software in 2026

Software plays a crucial role in the billing process, so buyers now weigh whether to build, buy, or outsource it.
Billing versus RCM

Billing versus RCM

Medical billing software creates, scrubs, and submits claims, while revenue cycle management surrounds it, so buyers should set scope before they develop medical billing software.
Build versus outsource

Build versus outsource

Outsourcing hands off the work but not control, so billing companies and healthtech teams increasingly build medical billing software they own rather than rent a billing solution.
Beyond off-the-shelf

Beyond off-the-shelf

When complex billing rules do not fit a product, custom medical billing software development gives healthcare organizations the workflows and software solutions their process actually needs.
Interoperability first

Interoperability first

Modern billing systems in healthcare live or die on EDI and FHIR, so the right medical billing software must connect cleanly to payers and clearinghouses.

Patient payments

Give patients clear statements and healthcare payment options that improve collections.

“Physicians complete an average of 39 prior authorizations per week, spending about 13 hours on the process.” — American Medical Association

That workload runs on phone calls and faxes, so automating prior authorization through EDI and FHIR removes one of the slowest steps in the revenue cycle.
The Revenue Cycle

All Billing Processes, One System

Revenue leaks between steps, so we build billing solutions that carry a claim cleanly across the entire billing process from access to payment.
01

Patient access

Front-end eligibility and prior authorization confirm coverage before care, cutting denials downstream.
02

Charge and coding

Charge capture and medical coding turn each encounter into an accurate, billable medical claim.
03

Claims and remittance

Claim submission and 835 remittance move billing information between provider and payer systems.
04

Denials and payment

Back-end denial work, payment posting, and collections recover revenue the first pass missed.

Payer Connectivity

Built to Reach Every Payer

Every claim and payment crosses a payer boundary, so we engineer connections that keep money moving instead of stalling in rework.
Faster payment
Fewer surprises
Ready for what's next
Connections that hold

Claims to cash

Claims go out clean and remittance posts automatically, so payment reconciles without staff keying every line.
  • Electronic claims: professional, institutional, and dental claims validated and submitted through EDI 837 before they reach a payer.
  • Automated remittance: 835 payments posted straight to patient accounts, so cash lands faster with less manual work.

Coverage up front

Verifying coverage and authorization before care stops the denials that come from eligibility gaps later.
  • Real-time eligibility: coverage confirmed through EDI 270 and 271 before a claim is ever built.
  • Authorization tracked: prior authorization handled through EDI 278 and reconciled inside the billing workflow.

Modern payer APIs

As payers move to real-time APIs, FHIR keeps your billing software current instead of locked to legacy formats.
  • FHIR and Da Vinci: coverage discovery, documentation, and prior authorization automated through modern payer APIs.
  • Both pathways: systems that speak EDI and FHIR, since payer support still varies from plan to plan.

Reliable by design

A billing platform is only as good as its links to payers and clearinghouses, so we build those to stay up.
  • Clearinghouse integration: claims routed, acknowledged, and tracked across the clearinghouses your team already uses.
  • Legacy bridge: a standards-based interface that lets older billing systems reach modern payer APIs.

Denials and AI

Clean Claims, Fewer Denials

Denied and misadjudicated claims drain revenue, so we build the logic that catches problems on both the provider and payer sides.
Claim scrubbing
Denial prediction
Adjudication
AI coding

Catch errors early

Scrubbing checks each claim against payer and coding rules, so this software enhances billing accuracy before submission.
  • Rule engine: claims validated against payer-specific edits and coding standards, so avoidable billing errors never reach the payer.
  • Coding validation: ICD-10, CPT, and HCPCS checks that keep the medical billing process compliant and clean.
  • Real-time flags: errors surfaced to billers as claims are built, not after a payer sends them back.
Image slot

Fix claims first

Machine learning reads historical denials to streamline billing and flag the claims most likely to be rejected next.
  • Prediction models: ML trained on your denial history so billing staff work the riskiest claims first.
  • Appeal workflows: structured resubmission that recovers revenue instead of writing it off.
  • Root-cause analysis: recurring denial patterns traced to their source, so the same error stops repeating.
Image slot

The payer side

For payers and TPAs, we build auto-adjudication engines that apply configurable rules, process claims at scale, and support faster, more consistent claim decisions.
  • Auto-adjudication: rules that adjudicate clean claims automatically and route exceptions for review.
  • Payer rule engine: configurable logic so plans manage benefits, edits, and pricing without a rebuild.
  • Audit trail: every adjudication decision logged and explainable, so payment determinations stand up to review.
Image slot

Assisted accuracy

AI-assisted coding suggests and checks codes to improve billing on complex claims with fewer errors.
  • Suggested codes: models that propose ICD-10 and CPT codes from documentation for coder review.
  • Governed models: AI kept documented and auditable, so accuracy gains never compromise compliance.
  • Human in the loop: coders confirm every AI suggestion, so the model assists rather than decides.

How We Work

Our Development Process

You get a billing platform that fits your workflow and reaches payers cleanly, because scope, interoperability, and compliance are settled before the build, not patched after go-live.
Step 1

Discovery

Before any code is written, we map your billing workflow, payer mix, and compliance obligations, and identify every system the software will need to reach. This is where scope becomes clear, so the build that follows fits your process rather than forcing you to fit it.
  • Billing workflow mapped
  • Payer and EDI needs confirmed
  • Compliance scope set
Step 2

Architecture

We design the data model and the EDI and FHIR interfaces that the whole platform depends on, and decide how each integration will connect and stay secure. Getting this foundation right is what lets the system scale later without a costly rebuild.
  • Secure data model
  • EDI and FHIR interface design
Step 3

Build and validate

We develop in two-week sprints and validate claims, transactions, and compliance on every increment, with demos you review as the software takes shape. Testing runs alongside the build, so problems surface early instead of after go-live.
  • Claim and transaction testing
  • Security and compliance validation
Step 4

Deploy and support

We roll out in phases so live billing keeps running, then stay on to track payer and regulatory change and keep the system current. Support is backed by an SLA, so the platform stays reliable long after launch.
  • Phased, low-risk rollout
  • SLA-backed support and updates
Cost and Timeline

The Cost to Build Medical Billing Software

The cost to build medical billing software depends on scope, so these drivers shape any estimate.
check icon

Billing versus full RCM

A focused billing module costs far less than a full revenue cycle platform, so scope is the first driver of any medical billing software development services estimate.
check icon

EDI and payer integrations

Each EDI transaction and payer connection adds engineering, so the number of integrations shapes both timeline and budget more than feature count does.
check icon

Prior authorization automation

Automating prior authorization through the 278 transaction and Da Vinci FHIR adds capability that pays back in fewer manual tasks but extends the initial build.
check icon

Denial prediction and AI

AI-based denial prediction and coding depend on data readiness, so model work is scoped separately from the core billing software development process.
check icon

Payer-side adjudication

Building auto-adjudication and payer rule engines for payers or TPAs adds scale and rule-configuration work beyond standard provider-side billing.
check icon

Clearinghouse and volume

Clearinghouse connections and high transaction volume raise reliability and infrastructure requirements, which shape architecture and long-term cost.

Questions You May Have

What is medical billing software?

Medical billing software manages getting healthcare providers paid: it verifies eligibility, assigns codes, scrubs and submits claims, works denials, and posts payments. It exchanges data with payers through EDI X12 and, increasingly, FHIR.

What is the difference between medical billing and RCM?

Medical billing is the core process of creating, submitting, and collecting on claims, while revenue cycle management is the broader end-to-end process around it. Billing is one step inside RCM, so buyers should set scope before they build.

What EDI transactions do medical billing software solutions use?

The main X12 transactions are the 837 for claims, the 835 for remittance, the 270 and 271 for eligibility, and the 278 for prior authorization. Modern systems increasingly add FHIR APIs alongside X12.

How does automation streamline billing workflows like prior authorization?

Traditionally it uses the X12 278 transaction, which the software generates and tracks automatically. Newer systems add FHIR automation through the Da Vinci guides, and because payer support varies, systems usually handle both pathways.

How does software reduce claim denials?

It verifies eligibility up front and scrubs claims against payer and coding rules so errors are fixed before submission. Machine learning can also predict likely denials from historical data, so teams work the riskiest claims first.

Can a medical billing system integrate with our EHR?

Yes. Medical billing software can integrate with EHR and EMR systems, practice management software, patient portals, clearinghouses, and payer systems using HL7, FHIR, and EDI X12, so billing does not require duplicate entry.

What does it cost to develop medical billing software?

Cost depends on scope: a focused billing module costs far less than a full RCM platform with payer-side adjudication. The main drivers are the number of EDI and payer integrations, prior-authorization automation, and AI, and a precise estimate follows discovery.

Should we build, buy, or outsource medical billing?

Outsourcing handles the work but gives little control over software or data, and buying the best medical billing software product still constrains workflows. Building custom makes sense when billing is core to your business, such as for billing companies, healthtech, or payers.
