CMS Physician Fee Schedule
The published Medicare rates and payment rules behind most of the codes on this page.
Gynecologic oncology billing hinges on radical hysterectomy bundling, lymphadenectomy add-ons, and a parallel chemotherapy administration ladder with J-code waste reporting. Add 90-day global periods on radical surgery and prior auth on biologics, and general billers miss revenue on every case. MedFactor delivers gyn-onc-specific RCM that protects every claim.

From ovarian and cervical cancer to complex pelvic surgery, we tailor billing to the coding rules of every gynecologic oncology subspecialty.
Ovarian
Cytoreductive surgery, omentectomy (58943), debulking with lymphadenectomy, and intraperitoneal chemotherapy administration coding.
Cervical
Radical hysterectomy (58210/58200), pelvic lymph node dissection (38770), and chemoradiation coordination with appropriate bundling.
Endometrial / Uterine
Total laparoscopic hysterectomy (58570/58571), staging lymphadenectomy, and sentinel node biopsy coding accuracy.
Vulvar / Vaginal
Radical vulvectomy, partial vulvectomy, and inguinal lymphadenectomy with proper staged-procedure modifier 58 usage.
Trophoblastic
Hydatidiform mole evacuation, low-dose methotrexate chemotherapy tracking, and hCG-based follow-up E/M coding.
Complex Pelvic
Exenterative procedures, urinary diversion, pelvic reconstruction, and modifier 22 for increased procedural service.
Gynecologic oncology uniquely runs two billing tracks in parallel: a radical-surgery base with lymphadenectomy and omental add-ons, and a chemotherapy administration hierarchy (first hour, each additional hour, hydration, non-chemo IV) with J-code drug waste reported separately on JW. This dual-track complexity is the largest source of gyn-onc denials and leakage.
One surgical session bills a radical hysterectomy base with lymph node and omental add-ons, while a separate chemotherapy encounter bills the administration hierarchy with discarded drug waste on the JW modifier.

Our focus: We sequence the radical hysterectomy as the surgical base, add para-aortic lymphadenectomy and omentectomy as distinct add-ons, and bill BSO with modifier 51 where required. For chemotherapy, we bill 96413 as the first-hour base, 96415 for each additional hour, 96521 for hydration, and 96365 for non-chemo IV infusions — and report discarded single-use vial waste on the JW modifier so the practice is paid for every unit of administered and wasted drug.
Gynecologic oncology billing is governed by radical-surgery bundling, the chemo administration hierarchy, and J-code waste rules that general billing companies cannot navigate effectively.
Radical hysterectomy add-ons (lymphadenectomy, omentectomy) dropped or denied as bundled when billed without correct sequencing and modifiers.
Severity
96413 first-hour, 96415 add-on hours, and hydration/non-chemo codes mis-sequenced, losing the first-hour base and add-on-hour revenue.
Severity
Discarded single-use vial drug waste (JW modifier) not reported, forfeiting reimbursement for wasted chemotherapy units.
Severity
Post-operative visits within the 90-day global of radical hysterectomy billed separately and denied, or missed opportunity for modifier 22 complexity.
Severity
Same-day E/M with a procedure in the global period denied without modifier 25 supporting a significant, separately identifiable service.
Severity
High-cost biologics and chemotherapy agents denied for missing or expired prior authorization, delaying infusion and losing revenue.
Severity

Common questions from gynecologic oncology practices considering MedFactor’s specialty RCM services.
How do you bill a radical hysterectomy with multiple add-on procedures?
Radical hysterectomy is billed as one base procedure code plus add-on codes for distinct work performed in the same session. For cervical cancer, 58210 (radical abdominal hysterectomy with bilateral pelvic lymphadenectomy) or 58200 (with para-aortic lymphadenectomy) is the base, with 38770 (retroperitoneal lymph node dissection) and 58943 (omentectomy) as add-ons, and bilateral salpingo-oophorectomy (58953 components) billed with modifier 51 where the payer requires it. We sequence the highest-valued radical surgery code as the base, add each distinct procedure with the correct add-on code, and apply modifier 51 or 59 for legitimately separate procedures — preventing NCCI bundling denials while capturing every component of the surgical session.
How is lymphadenectomy coded with radical hysterectomy?
Pelvic lymphadenectomy is included in the radical hysterectomy base codes 58210 and 58200, so it is not billed separately when performed as part of those procedures. However, para-aortic retroperitoneal lymph node dissection (38770) is billed as an add-on when performed in addition to the pelvic dissection, and open lymph node biopsy (38530) is billed when only a sampling is performed. We verify NCCI edits before submission so lymphadenectomy is coded at the correct level — included in the base when bundled, add-on when extended, and distinct when sampled — preserving the legitimate lymph-node revenue without triggering bundling denials.
How does the chemotherapy administration hierarchy work?
Chemotherapy IV infusion is billed as a hierarchy: 96413 (chemotherapy administration, intravenous infusion, first hour) is the base, and 96415 (each additional hour) is billed for every hour of infusion beyond the first. Hydration is billed separately with 96521 (first hour) when it is the primary service, and non-chemo drug IV infusion uses 96365 (first hour) for supportive agents such as antiemetics. The chemotherapy administration code must be sequenced first when chemo is the primary reason for the encounter.
We bill the 96413 first-hour base on every chemo infusion, add 96415 for each additional hour, separate hydration and non-chemo infusions with the correct codes, and append the proper J-code for the drug supply — so every administration hour and every drug unit is captured.
How is J-code drug waste reported?
When a single-use vial of a chemotherapy drug is partially administered and the remainder is discarded, the discarded portion is reported on a separate claim line with the JW (discarded drug) modifier, while the administered portion is billed on its own line with the J-code for the drug (for example J9170 for docetaxel). Medicare and most payers require JW reporting for any discarded amount from a single-use vial so the practice is reimbursed for the wasted units. We log every discarded unit, report it on the JW modifier line with the drug J-code, and keep the waste documentation the payer requires — recovering revenue that most practices lose by billing only the administered dose.
How does the 90-day global period affect radical surgery billing?
Radical hysterectomy (58200/58210) carries a 90-day global period, meaning all routine post-operative visits and related care are bundled into the surgical payment and cannot be billed separately. To capture legitimate additional revenue we track the global period in the practice management system, document modifier 22 (increased procedural service) when the radical surgery is unusually complex — such as extensive adhesions, exenteration, or reconstruction — and bill only services that are genuinely unrelated or staged with the correct modifier (58 for staged, 78 for unplanned return). We do not bill routine global follow-up separately, and we ensure every legitimately billable out-of-global service is captured with the right modifier.
When is modifier 25 used with surgery?
Modifier 25 is appended to an E/M code when a significant, separately identifiable evaluation and management service is performed on the same day as a procedure — for example a pre-operative assessment or a separately documented decision-making visit on the day of a minor procedure or an infusion. Within a 90-day global period, modifier 25 only supports an E/M that is unrelated to the global surgery, so we document the medical necessity and the separate nature of the visit. Without modifier 25, the same-day E/M is denied as bundled into the procedure; without supporting documentation, the modifier 25 claim is denied on audit.
We pair every modifier 25 with the supporting note so the E/M is paid rather than denied.
