The Endometriosis Insurance Crisis
A System That Does Not Value Talent,Time or Risk
Endometriosis surgery is among the most complex, technically demanding, and time-intensive procedures in all of gynaecology. It requires years of specialised training, meticulous preoperative planning, and surgical precision that can span several hours across multiple organ systems. And yet, the reimbursement system treats it as though it were a routine, straightforward procedure — with predictable, damaging, and far-reaching consequences for surgeons, patients, and the future of endometriosis care itself.
The Preauthorization Nightmare
Before a single incision is made, the endometriosis surgeon must navigate one of the most frustrating obstacles in modern medicine — the preauthorization process. Requests are frequently denied on first submission, requiring time-consuming appeals that fall on already overstretched surgical teams. The criteria used by insurance reviewers are designed for simpler procedures and consistently fail to account for the multiorgan, deeply infiltrating nature of advanced endometriosis — consuming extraordinary administrative time before the real work has even begun.
The ICD-10 Code Problem
The available ICD-10 codes for endometriosis are woefully inadequate. They can describe general location — ovarian, pelvic, bowel — but cannot begin to capture the true complexity of the disease. There is no code that communicates deep infiltrating endometriosis involving multiple organ systems, dense adhesions obliterating the Pouch of Douglas, or disease encasing a ureter. Since insurance companies make reimbursement decisions based on these codes, the inevitable result is that the complexity of the surgery is chronically and systematically undervalued.
The CPT Code Crisis
The primary CPT code for laparoscopic endometriosis surgery — CPT 58662 — is expected to represent everything from a ten-minute ablation of superficial lesions to a four-hour excision of deep infiltrating disease involving the bowel, bladder, and ureters. The idea that one code can equitably describe both of those surgical realities is not just inadequate — it is absurd. Additional codes exist for specific components of complex surgery, but their application is inconsistent and frequently challenged by insurers.
The Bundling Problem
Bundling — the practice of grouping multiple procedures into a single reduced payment — is particularly damaging in endometriosis surgery. When a surgeon spends hours excising disease from the bowel, freeing a tethered ureter, and restoring normal pelvic anatomy, each step represents a technically distinct, highly skilled procedure. Bundling collapses that reality into a single diminished payment bearing no relationship to the time, skill, or complexity involved. In the perverse logic of bundling, the more complete and thorough the surgery — the very surgery that produces the best outcomes — the less proportionately the surgeon is compensated.
The RVU Problem
The RVUs assigned to endometriosis surgery codes do not reflect true operative time, years of specialist training, or the complexity of deep infiltrating disease. A procedure taking four hours and requiring multiple surgical specialists is reimbursed at a level that bears no resemblance to its true value — and certainly not to what equivalent complexity commands in any other surgical specialty. Low RVUs mean low reimbursement, and low reimbursement means that performing complex endometriosis surgery is, from a purely financial standpoint, deeply unattractive for surgeons and surgical programmes alike.
The Consequence — Surgeons Not Incentivised to Operate
The cumulative effect of inadequate coding, aggressive bundling, poor RVUs, and exhausting preauthorization battles is both predictable and devastating — surgeons are simply not incentivised to specialise in endometriosis surgery. The financial return on this specialisation is poor, the administrative burden is extraordinary, and the result is a critically small pool of truly expert surgeons. Patients travel hundreds of miles to access specialist care, waiting lists stretch for months, and the women who need the most skilled hands are the least likely to find them within a reasonable distance or within their insurance network.
The Out-of-Network Crisis
Because expert endometriosis surgeons are so few, and because the reimbursement environment makes network participation financially untenable for many specialists, a significant proportion of the best endometriosis surgical care is delivered out of network. For many women, this cost is simply unaffordable. They return to in-network generalists who lack the training to fully address their disease, undergo incomplete surgeries, their disease returns, and the cycle continues — perpetuated by the very system designed to protect them.
What Needs to Change
The path forward requires simultaneous action across the entire reimbursement system:
Expanded ICD-10 codes that accurately capture the complexity of advanced endometriosis
Dedicated CPT codes for the distinct components of complex endometriosis surgery
An end to inappropriate bundling of genuinely distinct surgical procedures
RVU recalibration reflecting true operative time, training, and surgical complexity
Streamlined preauthorization pathways recognising endometriosis as the complex multiorgan disease it is
Advocacy at CMS and insurer level to formally recognise endometriosis surgery as the subspecialty it has always been
The Bottom Line
The women who need expert endometriosis surgery are not asking for a luxury. They are asking for complete, skilled, specialist care for a disease affecting more than ten percent of the female population. The reimbursement system, as it currently stands, makes delivering that care extraordinarily difficult — and accessing it even harder. The tools to fix this exist. What has been missing is the collective will to use them.
