About coding autosomal site fragile
The ICD-10-CM code for autosomal site fragile is Q95.5 (Individual with autosomal fragile site).
Within Q95 (balanced rearrangements and structural markers, not elsewhere classified), Q95.5 is specifically for individual with autosomal fragile site. Related codes cover 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), other balanced rearrangements and structural markers (Q95.8) and balanced rearrangement and structural marker, unspecified (Q95.9).
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.
