81234 Dmpk gene detc abnor allele
Also known as: DMPK repeat analysis, Myotonic Dystrophy 1 testing
Molecular analysis of the DMPK gene to detect abnormal CTG repeat expansions associated with Myotonic Dystrophy type 1.
In Plain Language
muscular dystrophy gene test; myotonic disorder genetic screening
Clinical Context
Used to diagnose Myotonic Dystrophy type 1 by measuring CTG trinucleotide repeat length for phenotype prediction and carrier status determination.
RVU Information
CPT 81234 does not have a physician work RVU assigned by CMS. Reimbursement for this code is determined by payer-specific fee schedules.
Billing & Documentation
Lab and pathology codes require an order from the treating provider with clinical indication. For molecular pathology and genetic testing, document the specific analytes tested and clinical rationale.
