Procedures Performed

Common outpatient procedures performed at this ambulatory surgery center, based on reported specialties.

Cataract SurgeryThe clouded natural lens of the eye is removed and replaced with a clear artificial one. It is one of the most common outpatient procedures performed in the country, usually takes under 30 minutes per eye, and is done under light sedation with numbing drops rather than general anesthesia.LASIK / Refractive SurgeryA laser reshapes the cornea to correct nearsightedness, farsightedness, or astigmatism, reducing dependence on glasses or contacts. The procedure itself takes minutes per eye. Vision is often noticeably better within a day, though it can take several weeks to fully stabilize.Glaucoma SurgeryCreates a new drainage path for fluid inside the eye to lower internal pressure. Glaucoma damages the optic nerve silently, so the goal is preventing further vision loss rather than restoring vision already lost. Several minimally invasive options are now performed in outpatient settings.Retinal SurgeryRepairs the light-sensitive tissue at the back of the eye, most often for a detached or torn retina, or for bleeding related to diabetes. Timing matters — a detaching retina is treated urgently because delay increases the risk of permanent vision loss.Eyelid Surgery (Blepharoplasty)Removes excess skin and fat from the upper or lower eyelids. When drooping upper lids block part of the visual field, the procedure is functional rather than cosmetic and is often covered by insurance if visual field testing documents the obstruction.Corneal TransplantReplaces damaged or clouded corneal tissue with donor tissue. Modern techniques often replace only the affected layer rather than the full thickness, which shortens recovery. Vision improves gradually over months, and stitches may stay in place for a year or longer.
Knee ArthroscopyA camera and small instruments are inserted through incisions the size of a buttonhole to repair cartilage, trim a torn meniscus, or remove loose fragments. Because the joint is not opened fully, recovery is far faster than traditional open knee surgery.Shoulder ArthroscopyUses a small camera and instruments through tiny incisions to repair the shoulder joint — commonly for impingement, labral tears, or damaged cartilage. Most patients go home the same day and begin physical therapy within the first week.ACL ReconstructionRebuilds the torn anterior cruciate ligament using a graft, since a fully torn ACL does not heal on its own. The surgery itself is outpatient, but returning to cutting and pivoting sports typically takes nine to twelve months of structured rehabilitation.Rotator Cuff RepairReattaches torn tendons in the shoulder to the bone. Pain relief often comes well before strength does — a sling is typical for several weeks and full recovery commonly takes four to six months, with physical therapy doing much of the work.Carpal Tunnel ReleaseCuts the ligament pressing on the median nerve at the wrist to relieve numbness, tingling, and night pain in the hand. The procedure takes about 15 minutes under local anesthesia. Night symptoms often improve immediately; grip strength returns over several weeks.Joint ReplacementDamaged joint surfaces are replaced with implants, most commonly at the knee or hip. Once exclusively a hospital procedure, selected healthy patients now have this done at surgery centers and go home the same day with a structured recovery plan.
Tonsillectomy / AdenoidectomyThe tonsils and sometimes the adenoids are removed for repeated infections or sleep-disordered breathing. Recovery is notably harder for adults than children, with significant throat pain for a week or more and a real emphasis on staying hydrated.Ear Tube PlacementTiny tubes are placed through the eardrum to drain fluid and ventilate the middle ear, most often for children with recurrent ear infections. The procedure takes about 10 minutes and the tubes usually fall out on their own within a year.Sinus Surgery (FESS)A camera and instruments passed through the nostrils open blocked sinus drainage pathways, with no external incisions. Considered for chronic sinusitis that has not improved with medication. Congestion often worsens briefly before it improves.SeptoplastyThe wall of cartilage and bone between the nostrils is straightened to improve airflow through a blocked side. It addresses breathing rather than external appearance, though it is sometimes combined with cosmetic reshaping.Turbinate ReductionSwollen tissue inside the nose is shrunk to improve airflow, frequently at the same time as septoplasty. Often the difference between a nose that is structurally straight and one that actually feels open.LaryngoscopyA scope examines the voice box and vocal cords, used for persistent hoarseness, difficulty swallowing, or throat pain that has not resolved. Small lesions can sometimes be biopsied or removed during the same procedure.
Breast Augmentation / ReductionBreast size is increased by placing implants, or decreased by removing breast tissue and skin and repositioning the remaining tissue. Reduction is often performed to relieve back, neck, and shoulder pain caused by breast weight.RhinoplastySurgery that reshapes the nose by altering the bone and cartilage beneath the skin. It is performed to change appearance, to correct breathing problems caused by internal structure, or both. Swelling takes months to fully resolve.FaceliftLiposuctionFat is suctioned out from beneath the skin through small tubes called cannulas, reshaping a specific area such as the abdomen, flanks, or thighs. It targets localized deposits and is a contouring procedure rather than a method of weight loss.Wound ReconstructionRebuilds skin and underlying tissue where a wound is too large or too damaged to close directly. Surgeons move nearby tissue, or transfer skin and muscle from elsewhere on the body, to cover the defect. Often follows trauma, infection, or cancer removal.Skin GraftingHealthy skin is taken from one area of the body and transplanted to cover a wound or burn elsewhere. Both the graft site and the donor site need care, and the donor site is often the more uncomfortable of the two.
Bunion Correction (Bunionectomy)The bony prominence at the base of the big toe is removed and the bone realigned, often with screws or plates. Recovery involves weeks in a protective shoe or boot, and swelling can persist for several months.Hammertoe CorrectionA toe permanently bent at the middle joint is straightened, sometimes with a temporary pin holding the correction. Considered when the toe rubs painfully in shoes or has developed calluses and sores.Plantar Fascia ReleaseThe tight band of tissue along the bottom of the foot is partially released to relieve stubborn heel pain. Reserved for cases that have not improved after months of stretching, orthotics, and other conservative treatment.Ankle ArthroscopyA small camera and instruments treat problems inside the ankle joint — impingement, loose fragments, or damaged cartilage — through incisions a few millimeters wide, avoiding a larger open exposure.Ingrown Toenail RemovalThe edge of a nail growing into the surrounding skin is removed under local anesthesia. When the problem keeps recurring, the nail-forming tissue at that edge is also treated so it does not grow back.Foot Fracture RepairBroken bones in the foot are realigned and stabilized with hardware so they heal in position. Because the foot bears your full weight with every step, alignment matters more here than the small bone size suggests.

I wish I could give the Kaiser system NW a better review. This is for all kaiser in Portland. Not just interstate. Access to the medical care/appointments is simply awful . It is frustrating and makes me feel unsupportive. When kaiser commercials pop up and they talk about how great and compassionate they are, my eyeballs roll up into the eyeball sockets. One day I am sure they will get stuck there. Example, today I went to schedule some appointments. My physician wanted me to schedule a follow up appointment in person or virtual in 3 weeks. Nothing available for 6 weeks. Mammogram 3 months. Cardiology follow up 'nothing available at this time', Appointment for low back injection "Nothing available at this time". What is the point of having medical insurance if you cant use it? To my doctor I would give a 5 star review. It took a while to find a doctor that would listen and work with me but I did and she is awesome (when I get an appointment), I would also give 4- 5 stars for the majority of physicians and employees that I was actually able to schedule with. (dont get me started on the cookbook medicine approach) Kaiser has good people but a crappy system

At my previous appointment with Dr. Cohen-Tanugi, we discussed the option of an in-office procedure to address the issue of Dupuytren's Contracture affecting my left hand. During the 12/7 visit, Dr. Cohen-Tanugi performed an ultrasound to determine which fingers were eligible for non-surgical treatment. Dr. explained that the pinkie finger was the only candidate for the needle procedure. I felt that the result was the best result, given the condition of my fingers. Today, I have more mobility in the pinkie. Additionally, my left hand seems more flexible, in general. I appreciate Dr. Cohen-Tanugi's ability to make the process understandable. He takes time to be congenial, and then gets down to business. Making appointments with his office was effective.

They have a revolving door, an elevator, and offices. It definitely met my expectations for a doctor's office. In fact, they have many offices in one building. The staircase has carpet on the stairs which was a really nice touch. Would definitely visit again if I had a doctor's appointment. Didn't get 5 stars because of the ambience and the food options but lots of people were there so I can tell doctor's offices are having a moment right now.

Dr. Foege is extremely skilled at administering my cervical epidural steroid injections. He's the only provider that I will allow to do this procedure. I don't know what I'd do if he ever left Kaiser. His team is also wonderful. They treat me with respect and kindness every visit. Thank you all for your excellence.

I was seen on 11/4/25 by Dr. Jean B. Ross MD. Right away she was attentive, proactive, listened, truly observed me, and thoroughly examined me, and got all necessary and presumptive lab results to rule anything out and identify what is actually going on inside my body. She knew exactly how to treat it and what to do in my specific situation which happened to include factors making some traditional treatment methods more difficult. She did everything she could to make me comfortable and offered a transfer to the ED if I felt like I could not take appropriate care for myself at home. I felt comfortable going home so I made that choice. The most surprising compassionate moment came when in the middle of a busy day, a new day, new patients, took the time to remember me and called me this morning to check on me and see how I was doing. I let her know that her treatments were helping my physical symptoms but I could not retain any food or water. Everything came right back up. She mentioned she was worried about this and then asked if I was able to come back in to get some fluids. I came back upon her request and got the fluids I needed. I feel so much better after that. I still have pneumonia, but it feels much more tolerable. Her compassionate care and careful attention is the reason why I am functioning at a normal level right now. Because of her help, I am able to drink sips of water over time and eat small amount of soft or puréed food without vomiting it back up. Because of her help I am able to take care of myself and feel the best that I can going through this. I am extremely grateful for Dr Jean B. Ross MD and all the staff that helped on 11/4/25 and 11/5/25. They are all outstanding!! But Dr. Ross deserves a special thanks and deserves public and peer appreciation on how dedicated she is to patients she does not care for on a regular basis. She is extremely kind, caring, and immediately knows how to build a great rapport with patients. She is detailed in her charting, ensuring accurate information and adding addendums when new information is available or if there is any follow up that took place. She went above and beyond any physician I have ever met (and I have met a lot within the Kaiser network) and she is the most outstanding provider I have ever met. I wish she worked in primary care because I would switch to her in a heart beat. She is willing to do what it takes to ensure her patients have the best care and best prognosis. I cannot thank her enough. I was seen by my primary doctor for this the day before seeing Dr. Ross. I was barley examined, and only ordered a basic strep A test. But it was the dedication to patient care, being actually caring and compassionate and empathetic for patient outcomes. Thinking about what obstacles they face not being in a medically monitored facility. She thinks about how the treatment I receive here will impact how I am able to sleep, work, eat, drink fluids, be in a clean safe environment and guidance on promoting good ways to have a good healing environment outside of the medical center. Dr Ross deserves direct praise from peers and her leadership team. I wish I could give her a raise or a bonus or a reward myself. She is very deserving of something very special to reward and celebrate the work she does and the positive impact she has on Kaiser Permanente and the community that she serves. Please whoever reads this please please make sure she gets some kind of reward or something physical to commemorate the good name she gives Kaiser and her hard work and dedication to the Interstate Urgent Care department. Please!!! She needs to be recognized!!!
