We are analyzing (not simply counting) 30 metaphases and performing 4 karyotypes. What is the correct way to bill this test?

Thank you for your question.
The correct coding would be 88264, 88285

88264-Chromosome analysis; analyze 20-25 cells
88285-Code 88285, Chromosome analysis; additional cells counted, each study, covers all additional cells counted and, therefore, should be reported once. The descriptor indicates the analysis of additional cells (plural).

Our understanding of the cpt manual is that when the verbiage "each" is used, it signifies the ability to bill that code with multiple units- an example is 88280 which also pluralizes the word karyotypes and indicates each study. 88285 should be able to be billed with multiple units.

Please see the coding tips and CPT assist information below.


Question: Is code 88285 appropriately reported for each additional cell counted beyond the number specified in the base code (eg, 88261 or 88262), or does it cover all additional cells counted for the study (ie, single test result)?

Code 88285 does not specify the number of additional cells, and is reported once regardless of the number of additional cells scored.
