The honest version of "does it integrate with my software." These are the systems this industry actually runs on, and what each one means for a build.
Athenahealth / eClinicalWorks / NextGenEHR and practice management
The systems of record for independent practices — charting, scheduling, billing and patient portal. Integration generally runs through vendor programs or standards-based interfaces, which is a real but navigable process.
Epic / CernerEnterprise EHR
Where the practice is affiliated with a health system. Integration is a formal process with the system's own governance, and should be scoped as such rather than assumed.
ClearinghouseClaims
Availity, Change or similar, carrying eligibility, claims and remittance. The place where denials surface and where a great deal of avoidable rework originates.
Prior authorizationPayer workflow
Payer portals, fax and phone, differing by payer and by procedure. One of the purest examples in any industry of a high-volume job with no standard interface.
Patient communicationFront office
Reminder, recall and two-way messaging platforms, plus the patient portal. Where most patient-initiated contact arrives.
Referral managementCoordination
Inbound and outbound referrals, still substantially fax-based, and a common place for patients to be lost between practices.
Revenue cycleBilling
Either in house or outsourced. Denial management and aged claim follow-up are the highest-value recurring work.
CredentialingCompliance
Provider enrollment and revalidation with each payer, on staggered cycles, with revenue consequences when a date is missed.
