This is a patient demand report for sports medicine and cartilage restoration practice owners and marketing leads. It shows what patients pay for MACI and microfracture, how MACI is billed and approved, what the evidence patients read says, and what they find when they search before they call. The practice-side facts come first; the patient detail below is the evidence behind them.
For practice owners: what this search looks like from your side
Some facts, side by side.
Vericel reported MACI revenue of $239.5 million for 2025, up 21% from $197.3 million, with a record number of implanting surgeons and biopsies in the fourth quarter, and guided to $280 to $286 million for 2026. (Vericel full-year 2025 results)
In one military cohort of 58 biopsied knees, 55.2% went on to MACI within two years. (Arthroscopy, Sports Medicine, and Rehabilitation, 2026)
The patient deciding between the biopsy and the implant waits roughly a month for insurance approval. The manufacturer reports an average turnaround of 25 to 30 days.
When I reviewed the pages that rank for this question, most gave one price line per option, several were copies of the same figures, and none explained the two-stage process or the insurance wait.
What those mean together for your practice is for you to work out.
If you want a second opinion on how your cartilage restoration pages and patient communication look from the patient’s side, book a 30-minute call. I will look at your site and your market before we talk. You can also read what a page like this is worth to an orthopedic practice.
What patients pay
Microfracture is the cheaper, simpler option. The surgeon makes small holes in the bone under the damaged cartilage so that a repair tissue can form. A US insurance database study found average total charges of about $7,259 per patient for microfracture, including the surgery and the care before and after it. (Orthopaedic Journal of Sports Medicine, 2015)
Autologous chondrocyte implantation, the family MACI belongs to, cost about $16,017 per patient in the same study. Those figures come from 2008 to 2010 data and did not break out the cost of the cells themselves, so they are a floor rather than today’s price. MACI also bills the lab-grown implant separately, on top of the two procedures.
The clearest long-run view comes from a German insurance study of 127 matched pairs followed for five years. In the year of surgery, MACI cost about €14,804 against €5,459 for microfracture. In years two and three, costs were close. In years four and five, MACI patients cost slightly less than microfracture patients. (Orthopaedic Journal of Sports Medicine, 2019)
So MACI is far more expensive up front, and the difference shrinks the longer the follow-up runs.
Two procedures also means two recovery periods, two sets of facility and anesthesia charges, and a gap in between.
What Medicare pays your practice
On the surgeon side, the CMS 2026 Physician Fee Schedule (October release) sets a national facility fee of $1,494.69 for the MACI implantation code and $623.26 for arthroscopic microfracture of the knee (CPT 29879), before geographic adjustment. The implant itself is billed separately, and I have not found a public 2026 Medicare figure for it. The sources also cover how MACI is billed and how long approval takes.
According to Vericel’s reimbursement guide, MACI is billed with CPT 27412 for the surgery and HCPCS J7330 for the implant, and the company’s MyCartilageCare program helps with the insurance process. Vericel reports that 89% of MACI cases activated in 2022 were approved on initial submission, with an average turnaround of 25 to 30 days. (Vericel MACI reimbursement guide)
Those are the manufacturer’s own figures. From the patient’s side, the experience is a wait of about a month between deciding and getting approval, and what they are told depends on how your office handles their insurer.
What the evidence patients read says
The trial behind MACI’s approval, SUMMIT, randomized 144 patients to MACI or microfracture. At five years, MACI’s advantage on the combined pain and function score was maintained and was statistically significant. (American Journal of Sports Medicine, 2018)
That advantage, and the German finding that later-year costs run lower, is the main argument patients will read for paying more up front. For a small defect in an active patient, microfracture is often still the first step. For a larger defect, or after a microfracture that did not hold, MACI is where many surgeons turn.
Who patients are
MACI is approved for symptomatic, full-thickness cartilage defects of the knee in adults. Its label notes that effectiveness in joints other than the knee, and safety and effectiveness in patients over 55, have not been established. (MACI prescribing information, revised 9/2025)
| MACI | Microfracture | |
|---|---|---|
| Number of procedures | Two (biopsy, then implant) | One |
| What repairs the defect | The patient’s own cartilage cells, grown in a lab on a membrane | Repair tissue from the bone marrow |
| Billing | Surgery code CPT 27412 plus the implant, HCPCS J7330 | Arthroscopic procedure only |
| FDA status | Approved in 2016 | Long-established surgical technique |
The MACI patient goes through two steps. The first procedure takes a small sample of their healthy cartilage. The cells are grown in a lab, seeded onto a membrane and sent back for a second surgery, where they are implanted into the defect.
Not every biopsy leads to the implant. In the military cohort cited above, 55.2% of 58 biopsied knees went on to MACI within two years.
Cartilage damage often comes with other knee injuries. My pages on ACL reconstruction cost and meniscus surgery cost cover the most common ones, and knee replacement cost covers the end of the road that cartilage repair aims to delay.
Questions patients ask before they book
These are the questions your page and your front desk need to answer.
- How large is the defect, and where is it? A good page explains that size and location drive the recommendation.
- Is the patient within the approved age range? A good page states that MACI’s safety and effectiveness over 55 have not been established.
- What will each of the two MACI procedures cost? A good page explains that there are two estimates, and the front desk provides both in writing.
- How long does approval usually take with their insurer? A good page gives your office’s own experience, not only the manufacturer’s figure.
- If microfracture fails, what is the next step and its cost? A good page names the revision options and links to them.
What a page that wins this search includes
- The two-stage process, explained as a timeline. Biopsy, lab growth, approval wait, implant. None of the ranking pages I reviewed explained it.
- Both costs, stated plainly. The first-year gap and the five-year view side by side, so the higher up-front price has its context.
- What happens between the biopsy and the implant. The insurance wait, who calls the patient, and what the next step is. None of the ranking pages covers that gap.
- Your own approval experience by payer. The manufacturer’s 89% figure is useful, and your own record is more persuasive.
- The evidence linked. SUMMIT and the German cost study, so the reader can check both.
Frequently asked questions
How much does MACI cost compared with microfracture? Much more in the first year. A German study found about €14,804 for MACI against €5,459 for microfracture in the year of surgery, with costs converging over the following years.
Does insurance cover MACI, and how long does approval take? Often, yes. The manufacturer reports 89% of 2022 cases approved on initial submission, with an average turnaround of 25 to 30 days.
Is MACI worth it if microfracture is cheaper? It depends on the defect. The SUMMIT trial found a lasting advantage in pain and function at five years for MACI, and later-year costs ran lower in one large study.
Is there an age limit for MACI? MACI’s label says safety and effectiveness in patients over 55 have not been established.
What happens if a microfracture fails? Revision options include MACI or other cartilage restoration procedures. Which one fits depends on the defect.
