ICD-10-CM Code Q93.5
Other deletions of part of a chromosome

Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
POA Exempt
POA Exempt Code
The Center for Medicare & Medicaid Services (CMS) requires medical coders to indicate whether or not a condition was present at the time of admission, in order to properly assign MS-DRG codes. This "Present On Admission" (POA) indicator is recorded on CMS form 4010A.
| ICD-10 from 2011 - 2016

Q93.5 is a billable ICD code used to specify a diagnosis of other deletions of part of a chromosome. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

POA Indicators on CMS form 4010A are as follows:

IndicatorMeaningCMS Will Pay CC/MCC DRG Costs
YDiagnosis was present at time of inpatient admissionYes
NDiagnosis was not present at time of inpatient admissionNo
UDocumentation insufficient to determine if the condition was present at the time of inpatient admission.No
WClinically undetermined. Provider unable to clinically determine whether the condition was present at the time of inpatient admission.Yes
1Exempt from POA reportingNo

The ICD code Q935 is used to code 9q34 deletion syndrome

9q34 deletion syndrome, also known as kleefstra syndrome, is a rare genetic disorder. terminal deletions of chromosome 9q34 have been associated with childhood hypotonia, a distinctive facial appearance and developmental disability. the facial features typically described include arched eyebrows, small head circumference, midface hypoplasia, prominent jaw and a pouting lower lip. individuals with this disease may often have speech impediments, such as speech delays. other characteristics of this disease include: epilepsy, congenital and urogenetic defects, microcephaly, corpulence, and psychiatric disorders. from analysis of chromosomal breakpoints, as well as gene sequencing in suggestive cases, kleefstra and colleagues identified ehmt1 as the causative gene. this gene is responsible for producing the protein histone methyltransferase which functions to alter histones. ultimately, histone methyltransferases are important in deactivating certain genes, needed for proper growth and development. moreover, a frameshift, missense, or nonsense error in the coding sequence of ehmt1 can result in this condition in an individual.

Other autosomal deletions (approximate match)

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code Q93.5 and a single ICD9 code, 758.39 is an approximate match for comparison and conversion purposes.

Parent Code: Q93 - Monosomies and deletions from the autosomes, not elsewhere classified
