Many industries require permission before action construction, business operations, public events. Medicine is not an exception. Providers in medical billing usually require prior approval to carry out some procedures or administer certain medications. This additional step goes by the name prior authorization (PA) or pre-authorization.
But why is prior authorization required in medical billing? Insurance companies employ it to manage costs, confirm medical necessity, and avoid fraudulent claims. It may seem like an administrative barrier but also keeps providers and patients safe from unnecessary costs.
Medications that often require PA Include:
- Specialty drugs for conditions like cancer or rheumatoid arthritis
- High-cost medications with lower-cost alternatives
- Newly approved or investigational drugs
- Medications for specific age groups
- High-dose prescriptions with addiction risks
Medical procedures that commonly necessitate PA are:
- Advanced imaging (MRI, CT scans, PET scans)
- Surgeries (non-emergency or elective surgeries)
- Long-term or expensive therapies (chemotherapy, rehab)
- Home healthcare services
- Cosmetic or non-urgent procedures
Emergency services typically do not require prior authorization, but nearly all other complex or costly services may.

- Practice type
- Primary care, two locations
- Location
- Southwest US

- 9 providers, 5 onboarded during engagement
- Engagement length
- Ongoing, quarterly reporting

| Month 3 | 34 | After engagement |
| Month 4 | 30 | After engagement |

The challenge
The practice was hiring faster than it could credential. Enrollment applications were filed reactively after a provider started, revalidation dates were tracked by memory, and claims for newly hired providers were held for months before anyone could bill them.
Our approach
Credentialing was coordinated around the onboarding calendar rather than the start date, so applications were filed before a provider arrived. Revalidation moved onto a maintained schedule, and billing workflows were connected to enrollment status so held claims were released the day participation was confirmed.
How the engagement unfolded
- Month 1 Backlog triage Listed every open provider–payer combination and sequenced it by revenue impact rather than by submission date.
- Month 2 Ahead of the start date Moved enrollment filing to the offer-acceptance point, so paperwork runs while a provider is still working out their notice.
- Month 3 Revalidation calendar Put every existing provider on a maintained revalidation schedule instead of tracking renewals informally.
- Ongoing Quarterly review Enrollment status and clean-claim performance reported together each quarter as the practice keeps hiring.
New providers used to sit idle on the billing side for months. Now their enrollment is done before their first clinic day.
