I hope someone can help us with this confusing question!! If a Nephrologist has been referred to do a consult to manage dialysis for an ESRD patient admitted to the hospital for other reasons than renal, can you code for a consult (99254) and dialysis (90935)? We tried using modifier 25 with the E/M code but it has been getting denied. Medicare is paying for the dialysis (90935) only.
