Are extra lower back x-ray views covered by insurance?
Often yes, but only when the note says why the basic set was not enough. Code 72110 is the low back x-ray shot with four or more angles, adding the oblique views a two or three angle set leaves out. Plans treat it as diagnostic imaging, so it lands against the deductible before any coinsurance kicks in.
Often
Extra views need a written reason
Four or more views
The extra angles are the whole difference between 72110 and the basic lumbar set. Bill it with no note explaining them and the payer drops you back a code.
Red flags win
Trauma, numbness, weakness, unexplained weight loss or a cancer history in the chart is what makes added lumbar angles read as medically necessary.
Once a year
Some plans allow one lumbar series every twelve months. A film shot at an urgent care last spring can use up that benefit before your patient walks in.
Ask the plan first
Some plans want added views approved in advance. The check before the visit surfaces plan status, deductible left and prior authorization flags where the payer reports them.
What would a real check show for this patient's 72110?
Pick a sample plan and type your fee. This is the visibility a real-time check gives the desk for every actual patient, in under a second.

Estimate from a sample plan. A real check reads the actual plan in under a second.
When 72110 beats the basic series
- Four or more lumbar angles were shot and reported
- The note says what the added angles looked for
- Red flag symptoms or trauma appear in the chart
- No lumbar series billed elsewhere inside the plan limit
Documentation payers expect
Payers expect the clinical question in writing, the number of angles, and a report naming the levels and directions shot. Studies from another office count against the frequency limit, so ask the patient where they have been.
Why extra lumbar views get denied
What the extra views usually lead to
Extra lumbar views tend to end one of two ways. Either care starts and 98941 with 97112 begins eating a visit limit the patient never saw, or the finding points to a lumbar MRI, 72148, which most plans review before approving and which arrives as its own bill from the imaging center. Some patients also leave with a back brace, L0650, and many plans pay for that only from an in network supplier. Checking the plan first means every one of those numbers is expected.
72110, quick answers
What makes extra lower back views covered instead of the basic set?
The note has to name the question the added angles were meant to answer. Without it, most payers pay the basic series rate or deny the line outright.
Does Medicare cover 72110 when the chiropractor takes it?
No. Medicare treats a chiropractor as a physician only for manual manipulation, so films taken or ordered by that office are not payable and the patient pays out of pocket. Say so before the film, not after.
How often will a plan pay for lower back x-rays?
Many allow one lumbar series a year. Films taken at an urgent care or another office count toward that, so it is worth asking the patient where they have been.
Do extra views need approval first?
On some plans, yes. Prior authorization flags come back on the eligibility check where the payer reports them, which is why it pays to run it before the appointment.
Why did the payer pay 72100 when we billed 72110?
That is a downcode. The report did not support the number of angles billed, so the payer priced the smaller lumbar study instead.
