Follow one-to-one crosswalk.
Despite a major CPT® revamping of genetic test codes (see "81200-81479: Get Ready for Molecular Pathology Overhaul" in this issue), you won’t see a similar change for reporting those test results when you change to ICD-10 on Oct. 1, 2014.
In fact, you can expect a direct crosswalk of a few ICD-9 codes to ICD-10 for reporting a limited number of molecular pathology test results.
Don’t Identify Gene
ICD-9 provides the following limited codes to report some genetic test results:
Each of the preceding codes crosswalks directly to the following codes:
Notice: Neither ICD-9 nor ICD-10 distinguishes the diagnosis codes based on the specific genetic test. For instance, physicians may select Z15.01 or Z15.02 based on BRCA-1 and/or BRCA-2 positive results from a test such as (but not limited to) 81211 (BRCA1, BRCA2 [breast cancer 1 and 2] [e.g., hereditary breast and ovarian cancer] gene analysis; full sequence analysis and common duplication/deletion variants in BRCA1 [i.e., exon 13 del 3.835kb, exon 13 dup 6kb, exon 14-20 del 26kb, exon 22 del 510bp, exon 8-9 del 7.1kb]).
