Hello. A patient was recently referred for HBOT from her radiation oncologist. Hx: In 2020, high grade urothelial carcinoma of bladder stage T2 N0. Bladder received total dose 6000 cGy at 200 Gy per fraction. The lower pelvic nodes received total dose of 4400 cGy. Chemo and radiation treatment completed in August 2020. Patient continued CT urogram every 3 months, cystoscopy every 6 months. Recurrence in Jan 2023. Bladder tumor via cystoscopy. Had transurethral resection of tumor, high grade urothelial carcinoma. Radical cystectomy with ileal conduit, anterior vagina resection.

6/19/23 CT with erosive changes to pubic symphysis. “Differential of ORN if radiation treatment to this area”. 7/31/23 PET with CT: “intensely metabolic erosive changes present centered on the pubic symphysis. Could represent infectious/inflammatory etiologies such as a septic joint.” MRI ordered in August 2023, do not have copy of results at this time. 9/9/23 – admitted. Diagnosis includes osteomyelitis of pubic bone. Started long term antibiotics. (do not currently have more details from admission, at this time).
Patient has 2-3/10 pain while sitting, 8-9/10 pain after walking currently.

Would it be appropriate to bring this patient in with ORN, however is not of the mandible? She has a diagnosis of OM in September 2023, underwent treatment with long term antibiotics and symptoms still continue. No debridement known at this time. Wanted to consider CROM as well. Also, STRN related to the pubic symphysis? Payor is Medicare.

Thank you!

Sarah, this is indeed a challenging case. You have been thorough to describe your findings to us —helpful. BUT, to Medicare (more specifically your fiscal intermediary), you have described a hodgepodge that makes no sense and would likely not be approved.

Others, feel free to jump in and give opinions.

If this were my patient, and I was doing an intake consultation, I would not address any of the confounding diagnoses and focus specifically on the STRN of the pubic area. I’m sure on physical examination that there are several other findings that you did not include, such as any open skin wounds, definite changes due to radiation … such as complete pubic hair loss in the radiated field, vaginal wall non-healing wounds, vaginal atrophy, etc. These (no matter how trivial) complete the diagnosis of STRN with non-healing latent effects of radiation in normal tissues (LENT).

You have stated that the patient is being treated for osteomyelitis, but there is no record of surgical procedure, debridement, culture, and sensitivity, etc … so, you really haven’t defined OM from a clinical standpoint for HBOT. That requires the above, plus appropriate antibiotics for at least six weeks, and then recurrence in the same location. And, I don’t see reference of an open, draining wound or fistula …. So, do not tell this story to Medicare. It will not pass muster.

Based on your fiscal intermediary, the diagnosis of ORN is limited entirely to the mandible. When I have a mixed problem like your patient, I suggest telling the story of multiple tissues being involved in the radiation area, with the final diagnosis (from an HBOT standpoint) of STRN.

This is just my opinion, I would encourage others to chime in here.

Thank you very much. I will ensure the documentation tells the story of one avenue for a single diagnosis, STRN, and include further applicable assessment details.
