ICD-10-CM Code Q93.2
Chromosome replaced with ring, dicentric or isochromosome
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.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.Q93.2 is a billable ICD code used to specify a diagnosis of chromosome replaced with ring, dicentric or isochromosome. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
POA Indicators on CMS form 4010A are as follows:
| Indicator | Meaning | CMS Will Pay CC/MCC DRG Costs |
|---|---|---|
| Y | Diagnosis was present at time of inpatient admission | Yes |
| N | Diagnosis was not present at time of inpatient admission | No |
| U | Documentation insufficient to determine if the condition was present at the time of inpatient admission. | No |
| W | Clinically undetermined. Provider unable to clinically determine whether the condition was present at the time of inpatient admission. | Yes |
| 1 | Exempt from POA reporting | No |
The ICD code Q93 is used to code 22q13 deletion syndrome
22q13 deletion syndrome (spoken as twenty-two q one three) is a genetic disorder caused by deletions or rearrangements on the q terminal end (long arm) of chromosome 22. Any abnormal genetic variation in the q13 region that presents with significant manifestations (phenotype) typical of a terminal deletion should be diagnosed as 22q13 deletion syndrome. 22q13 deletion syndrome is often placed in the more general category of Phelan-McDermid Syndrome (abbreviated PMS), which includes some mutations and microdeletions. The PMS name is less precise, since there is disagreement among researchers as to which variants belong in the PMS category. The Developmental Synaptopathies Consortium defines PMS as being caused by SHANK3 mutations, a definition that excludes terminal deletions. This latter definition of PMS is incompatible with the defintion of 22q13 deletion syndrome by those who first described 22q13 deletion syndrome.

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)
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 Q93.2 and a single ICD9 code, 758.5 is an approximate match for comparison and conversion purposes.
