Electronic billing (e‑claims) is standard — you submit claims electronically, and payers respond in days. But payment processing (collecting from patients) is the fastest‑growing process. The medical billing market forecast shows that payment processing is growing at over 14% CAGR, because patients are paying more out‑of‑pocket (deductibles, copays, non‑covered services).

What's driving this? High‑deductible health plans. Patients now owe hundreds or thousands before insurance kicks in. The medical billing market analysis notes that the fastest‑growing application is financial, as providers use payment portals, text reminders, and payment plans to collect from patients.

What's new? AI that estimates a patient's out‑of‑pocket cost before a procedure, reducing surprise bills and bad debt.

The bottom line: if you're a patient, ask for an estimate before treatment. If you're a provider, invest in payment technology. Cash flow is oxygen.
