The 47 Steps Between “You Need an Injection” and Actually Getting One

The day I tell a patient they need an injection, something shifts in the room. There’s relief — finally, a plan. A path forward. What they don’t know, and what I’m going to tell you today, is that the journey has barely started.

Here’s what actually happens.

The Office Visit

When I see you, I’m building a clinical picture from the moment you walk in. I watch how you sit down. I listen to where the pain radiates, what makes it worse, what you’ve already tried. I do a physical exam — testing reflexes, checking sensation, reproducing your symptoms. I review your MRI, correlating what the images show with what your body is telling me.

When I decide you need an epidural steroid injection or a nerve block, that call isn’t casual. It’s the result of everything above, synthesized in real time, cross-referenced against what the evidence says works. It’s medicine the way it’s supposed to work.

And then you leave. And the machine kicks in.

The Invisible Team

Within hours of your visit, my medical assistant is on the phone with your insurance verifying your benefits and confirming the procedure code. My scheduler is checking availability. My authorization coordinator — a dedicated role most patients don’t know exists — is pulling together everything your insurer will require to even consider approving the procedure.

You never see any of this. Most patients think approval is just a quick phone call. It is not.

The Prior Authorization Labyrinth

Prior authorization — prior auth — is insurance-speak for “prove to us this patient actually needs it.” Before they’ll pay for your procedure, your insurer needs documentation. A lot of it.

That means: full clinical notes. Imaging results. Every medication you’ve tried and how long. Every physical therapy session, with dates. Your pain scores — the 1-to-10 number you’ve been asked to rate at every visit — documented over time. Functional limitation spelled out in writing.

The insurance company has a checklist. They want proof that you’ve “tried and failed” conservative care before they’ll greenlight anything interventional. Six weeks of physical therapy. Two medication classes. Weeks of documented suffering.

I want to be very clear: I am not exaggerating. I am describing your policy.

What I want to say to every medical director who designed these criteria: sit in my exam room for a week. Sit with the 68-year-old woman who cannot walk to her mailbox. Then tell me she needs another six weeks of stretching before she’s earned her injection.

The LCD Problem

Medicare patients face an additional layer: Local Coverage Determinations, or LCDs. These are Medicare’s rulebooks — what they’ll pay for, under what conditions. They’re written by regional contractors, and not always by physicians who have spent a day treating spine pain.

They also change. Sometimes mid-year. Sometimes I discover a policy has shifted because an authorization comes back denied for a reason that didn’t exist last quarter. No memo. No warning. The goalpost moved and I was running toward where it used to be.

Running a practice under these conditions is like following a recipe that someone keeps editing while you cook. You adapt, you update your protocols. But patients sometimes wait longer because we’re racing to satisfy requirements that didn’t exist when we first saw them.

The Waiting Game

Once prior auth is submitted, we wait. The insurer has days — sometimes weeks — to respond. We follow up by phone. We send faxes. Yes, in 2025, the American healthcare system still runs substantially on fax machines, and I have made peace with exactly none of that.

Sometimes we’re asked for a peer-to-peer review: a call where I personally argue your medical case to a physician employed by the insurance company — who may be in a completely different specialty, who has never examined you — and who decides whether I am right about what you need. The audacity of that arrangement has never stopped bothering me.

The Denial and Appeal

Denials happen. We appeal. We resubmit with additional documentation, strengthened arguments, more clinical detail. Sometimes we win. Sometimes a second denial arrives anyway and we start over.

What insurers are counting on: attrition. That the friction will outlast the fight. That patients will give up. I’ve watched it happen. I refuse to let it happen without exhausting every option on my end first.

The Finish Line

When approval finally comes through, we schedule you, walk through your pre-procedure checklist, and get you in. The procedure itself — the thing we’ve spent weeks fighting for — often takes fifteen minutes.

Fifteen minutes of careful, image-guided work. Everything else happened before you ever walked into the procedure room.

To You, Reading This

If you’ve been waiting on an authorization and wondering why it’s taking so long, your frustration is completely valid. The system is not designed around your wellbeing. It is designed around cost containment, and there is a meaningful difference.

But behind every delay, there is a team that is not giving up. We are on the phone, on hold, writing letters, scheduling peer-to-peer calls, and resubmitting documentation. We are not stopping.

This blog exists because these conversations deserve to happen in the open. Come back. There is a lot more to say.
