When to see a nephrologist
Should I see a nephrology specialist?
Most patients reach our clinic through a referral, but you can also come directly if something on your labs or symptoms concerns you. Here are signs that specialty care is the right next step.
Abnormal kidney labs
Elevated creatinine, reduced GFR, or protein or blood in your urine on recent tests.
Blood pressure that won’t come down
Hypertension that needs three or more medications, or that has become harder to control lately.
Diabetes or hypertension — no recent kidney check
If you have either condition and haven’t had your kidneys checked in the last year, it’s worth a visit.
Persistent leg or ankle swelling
Especially if it’s new, symmetric, or worsening — an early sign of kidney or heart involvement.
Recurrent kidney stones
After more than one stone, a metabolic workup can identify what’s driving the problem and prevent future stones.
Family history of kidney disease
Polycystic kidney disease and hereditary nephritis run in families and deserve a baseline evaluation.
Not sure? Call (713) 597-5131 and ask to speak with someone in our intake team — we'll help you figure out whether a visit makes sense for you.
Heat & dehydration risk
Heat hits harder with kidney disease.
Impaired temperature regulation and common medications (diuretics, ACE inhibitors, ARBs) raise the risk of dehydration and acute kidney injury in hot weather. If you’re on a fluid restriction or dialysis, don’t simply drink more — ask your nephrology team how heat changes your prescribed limits.

What to expect
Your first nephrology visit at Remix Medical.
A first visit takes about an hour. You'll leave with a written plan in the patient portal the same day. Tap any step below for the details.
Before you arrive
Complete new-patient paperwork through the patient portal (about 15 minutes). Bring — or have your previous provider fax — recent lab work, imaging, and discharge summaries. Bring a list of every medication you take, including over-the-counter ones.
Arrive 15 minutes early
Our front desk verifies your insurance and collects any remaining paperwork. Plan for about 60 minutes total at the office for a first visit.
Your visit with the nephrologist
Expect a full kidney health history — how you got here, what’s been tried, what you’re worried about. Your nephrologist reviews labs and imaging, performs a focused exam, and explains what’s happening in plain language.
Your personalized plan
By the end of the visit, you’ll have a written plan covering what we think is going on, what’s changing about your treatment, what tests are next, and when we’ll see each other again. A copy lands in the patient portal the same day.
Follow-up
Most nephrology patients are seen every 3 to 6 months depending on the stage of disease. Between visits you can reach our office through the portal or by phone — messages are answered the same business day.
Our approach
Nephrology, remixed.
Most specialty care is fragmented — different clinicians each shift, different hospitalists every admission, referral loops that make you re-explain your story three times. Remix Medical is structured differently.
Continuity with one nephrologist
The same physician sees you at every visit — in the office, on dialysis rounds, after a hospital admission, post-transplant. One doctor who actually remembers your history.
Coordinated with your other specialists
Because Remix Medical is multispecialty, your nephrologist can walk down the hall to discuss your case with cardiology, pulmonary, or your primary care doctor — shared EHR, real conversations.
A practice that answers the phone
Lab questions, medication adjustments, prior-authorization issues — most are resolved the same day. On-call coverage for urgent concerns after hours.
Slower progression through better management
Aggressive use of kidney-protective medications (ACE inhibitors, ARBs, SGLT2 inhibitors where indicated), tight blood pressure targets, and medication review aimed at preserving the function you still have.

- ★★★★★
“Dr. Khosla is an excellent doctor. He is quick to answer your questions. He explains things to you and listens to your concerns. He is easy to talk to. He responds quickly when you reach out to his office. His staff and team are so good about getting back to you. He has been caring for my husband for almost 2 years and I couldn’t have picked a better doctor for my husband. I feel so confident and secure with Dr. Khosla being the kidney doctor on my husband’s medical team.. You won’t find a better doctor- believe me. My husband has a few doctors, but I have never met a doctor like Dr. Khosla. He is genuinely concerned about his patients and their well being. I will say this… I sure hope he doesn’t retire before my husband gets his kidney. Thank you for how you take care of my husband Dr. K.”

Frequently asked
Nephrology questions, answered.
Do I need a referral to see a nephrologist?
It depends on your insurance. Most PPO plans allow you to self-refer. HMO plans typically require a primary care referral. Medicare and Medicare Advantage rules vary by plan. Call (713) 597-5131 and our team will verify referral requirements for your specific plan in under a minute.
What lab tests evaluate kidney function?
The core tests are serum creatinine, blood urea nitrogen (BUN), estimated GFR (eGFR), and a urine albumin-to-creatinine ratio (UACR) to check for protein leakage. A complete metabolic panel evaluates electrolytes; urinalysis looks for blood, protein, and casts. Depending on findings, additional testing may include kidney ultrasound, 24-hour urine collection, or specific antibody panels for autoimmune kidney disease.
What's the difference between a nephrologist and a urologist?
A nephrologist is an internal medicine physician who specializes in the medical management of kidney disease — chronic kidney disease (CKD), hypertension, electrolyte disorders, dialysis, and transplant follow-up. A urologist is a surgeon who handles surgical care of the urinary tract — bladder and prostate conditions and surgical removal of kidney stones. Stone evaluation often involves both specialties.
Can I see the nephrologist by telehealth?
Established patients can use telehealth for many follow-up visits — lab reviews, medication adjustments, and routine chronic kidney disease (CKD) check-ins. New patients are typically seen in person for a first visit, then can transition to telehealth for follow-ups. Telehealth is covered by most commercial plans, Medicare, and Medicare Advantage.
Can I come to Remix Medical for a second opinion?
Yes. Many patients come to us for a second opinion on chronic kidney disease (CKD) management, dialysis decisions, or complex hypertension. Bring your most recent labs, imaging reports, and a list of medications. We’ll review your situation, confirm or refine the diagnosis, and either agree with the current plan or recommend changes. You’re never obligated to transfer care.
What medications should I avoid if I have kidney disease?
Several common medications can harm the kidneys, especially in patients with existing chronic kidney disease (CKD). The most frequent culprits are NSAIDs (ibuprofen, naproxen), certain contrast dyes used in imaging, and some antibiotics (particularly aminoglycosides). Over-the-counter herbal supplements can also be risky. Tell every doctor you see that you have kidney disease — it’s one of the most important things you can do to protect remaining function.
My kidney function is dropping quickly. Can I be seen urgently?
Yes. A meaningful creatinine rise over weeks, new heavy proteinuria, or sudden swelling all warrant urgent nephrology evaluation. Call (713) 597-5131 and explain the situation; we reserve same-day or next-day slots for urgent new referrals. If symptoms include severe shortness of breath, confusion, or you haven't urinated in 12+ hours, go to the emergency room.
