About coding balanced autosomal translocation
The ICD-10-CM code for balanced autosomal translocation is Q95.9 (Balanced rearrangement and structural marker, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q95.9.
Within Q95, choose Q95.9 (Balanced rearrangement and structural marker, unspecified) only when documentation doesn't support a more specific option: balanced translocation and insertion in normal individual (Q95.0), chromosome inversion in normal individual (Q95.1), balanced autosomal rearrangement in abnormal individual (Q95.2), balanced sex/autosomal rearrangement in abnormal individual (Q95.3), individual with autosomal fragile site (Q95.5) and other balanced rearrangements and structural markers (Q95.8).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
