Doctor explained things

“9/1/25 I had PRP yesterday to treat lumbar spine and SI joint pain. As always, the staff was great and made the procedure as smooth as possible.”

Staff and scheduling

“Dr. Tambar believes in profit over patient. Do not trust this guy. Ask your PCP to refer you to an infusion clinic. Leah works under him and follows his direction, I wish she was in her own practice.”

Reported improvement

“Great doctor and great practice. Dr. Tambar changed my life by diagnosing a problem no other doctor could crack. And his office is always efficient, professional and nice.”

Ask before you book

A clinic that answers these clearly is a different proposition from one that deflects. Take the list with you.

  1. 1Which specific product do you use, and is it my own tissue or a purchased donor product?
  2. 2Is it being used as a 361 HCT/P, or under an FDA investigational new drug application?
  3. 3Who performs the injection: the physician of record, or a PA or nurse practitioner?
  4. 4What is the total cost, and what happens if a second treatment is needed?
  5. 5What outcome data do you keep on your own patients for my specific condition?
  6. 6How many of these have you done for this indication, and what does a poor result look like?

What it is likely to cost

Siddharth Tambar, MD has not published pricing, which is true of almost every clinic in this category. Insurance almost never covers the injection itself, though the consultation, imaging and any conventional treatment in the same visit often are covered.

Ask for the total in writing, including whether a second injection is billed separately, and ask for the CPT codes so you can check coverage yourself before you commit.
