Medical Practice Billing, Credentialing & Revenue Support
MedWork Services helps U.S. medical practices and multi-specialty groups keep provider enrollment, medical billing and accounts receivable working together. We coordinate credentialing, payer enrollment, billing and AR recovery so providers are set up correctly before claims go out, and unpaid claims have a clear owner.
- Support across all 50 states
- Scope agreed before work begins
- No guarantees on approvals or collections
- The initial audit is complimentary
What problems do medical practices and multi-specialty groups run into?
As a group adds providers, locations and specialties, the administrative work multiplies. Every provider has a separate enrollment status with every payer. Each specialty brings its own coding and authorization rules. One missed attestation or revalidation can hold up a whole roster. Owners often notice only when claims start denying or AR keeps growing.
Common warning signs
- A new provider cannot bill under the group’s contract, and nobody can say when they can.
- The same payer pays some providers and denies others.
- AR rises while visit volume stays steady.
- No one can say which providers are active with which payers.
Why does this happen in multi-provider practices?
Payers load providers by NPI, taxonomy, tax ID and location. If any of those differ between NPPES, PECOS, CAQH and the payer’s own record, an application can stall or a claim can deny. Individual and group enrollments are separate approvals, and a contract or effective date can still be open after credentialing is finished. A single billing workflow rarely fits every specialty, and knowledge about who owns follow-up tends to leave when staff do.
How does it affect revenue and operations?
Providers who see patients before an effective date is confirmed may be exposed to nonpayment. Claims billed under the wrong provider, location or tax ID create denials that look like billing errors but start in enrollment. Aging AR hides which balances are recoverable. Retroactive enrollment is payer-specific and should never be assumed.
Our approach
How does MedWork Services support medical practices?
We begin with a roster-level view: every provider, location and payer on one sheet, so the gaps are visible before any work starts.
01
Build a provider, location and payer roster showing enrollment status and effective dates.
02
Align NPI/NPPES, CAQH, PECOS and payer records for individual providers and for the group.
03
Coordinate enrollment, contracting and revalidation, including new providers and new locations.
04
Review the billing workflow by specialty: eligibility, charge capture, coding handoffs, claim submission and ERA/EOB reconciliation.
05
Work aging AR and denials by payer and root cause, then feed what we find back into enrollment and billing.
The scope is agreed with your practice before work begins.
As you grow
What changes as a practice grows?
| Situation | What needs checking | Why it matters |
|---|---|---|
| Adding a provider | Individual NPI and taxonomy, CAQH profile, license, group affiliation under the existing contract | Applications are filed per provider and per payer, and effective dates are not automatic. |
| Adding a location | Address updates in NPPES, PECOS and CAQH, and the payer’s location record | A claim billed from a location the payer does not have on file can deny. |
| Adding a specialty | Specialty coding, authorization rules and taxonomy | One billing workflow rarely fits every specialty. |
| Changing tax ID, merging or acquiring a practice | Enrollment changes or new applications, contract assignment, EFT and ERA setup | Payments can be misdirected or stop. |
| A provider leaving | Payer, CAQH and PECOS records, and ownership of open AR | Outdated records cause misrouted claims and payer correspondence. |
Which practice types does MedWork Services support?
MedWork Services works with medical groups and clinics across the United States. Practice types we support include:
- Multi-specialty medical groups
- Rehabilitation providers
- Behavioral health practices
- Primary care and family medicine practices
- Specialty clinics
- Telehealth organizations
- New practices
Do not see your specialty or practice type here?
Every specialty has its own payer and coding rules, so please contact MedWork Services directly to confirm we can support it. If it is not a fit, we will tell you plainly.
What does your practice receive?
- A provider, location and payer roster with enrollment status and effective dates
- A tax ID and location map showing which entity bills under which contract
- A billing workflow and responsibility map by specialty
- A prioritized AR worklist and a denial root-cause summary
- A renewal, attestation and revalidation calendar
Is MedWork Services the right fit?
Good fit: practices and groups adding providers or locations, groups whose AR is growing without a clear reason, and owners who want credentialing, enrollment and billing handled as one connected process.
Not a fit: anyone looking for guaranteed collections or approval dates, coding that is not supported by clinical documentation, or legal and clinical advice. MedWork Services provides administrative revenue support only.
How long does it take?
In our experience, a clean Medicare enrollment application takes about 40 business days. Medicaid and commercial payers usually take 45 to 120 days, and some take longer. Treat these as planning figures, not promises. Timing depends on complete documentation, payer review queues, network availability and contracting. After reviewing your provider list and payer mix we agree on milestones. We do not guarantee approval, effective dates or collection amounts.
Clear answers
Questions practice owners ask
What is the difference between credentialing and payer enrollment for a medical group?
Credentialing verifies a clinician’s qualifications. Payer enrollment connects that clinician and the group to a payer’s billing system. Contracting can be a third, separate step. Our guide to provider credentialing and payer enrollment explains each one.
Can a new provider bill under our group’s contract right away?
Not automatically. It depends on the payer, the contract and the written effective date. Confirm the payer’s requirements in writing before treating a pending application as billable participation.
Do you handle billing for several specialties in one group?
Yes. We review the workflow for each specialty, because eligibility, authorization and coding needs differ. Codes must reflect the services documented by the clinician, and responsibilities are agreed before work begins.
Can you work with our current billing team and software?
Yes. The scope can cover a specific backlog, an enrollment gap or an audit. We work across systems such as Athenahealth, eClinicalWorks, AdvancedMD, Kareo, TherapyNotes, SimplePractice, DrChrono and Office Ally. Access and scope are confirmed during assessment.
Do you work with practices in every state?
We support administrative coordination in all 50 states, subject to each state’s, profession’s and payer’s requirements.
Do you work with my specialty?
Please contact MedWork Services directly to confirm. Each specialty has its own payer and coding rules, and we would rather confirm than assume.
Can you help with AR that is more than a year old?
We can assess older balances and identify the options. Timely filing limits, appeal rights and supporting records decide what is possible, and recovery cannot be guaranteed.
What should I prepare before the first call?
The number of providers, specialties, states, main payers and the main problem you want fixed. Please do not send patient information or PHI through the website, email, WhatsApp or Messenger.
