ICD-10-CM Code Q79.8
Other congenital malformations of musculoskeletal system

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.

Q79.8 is a billable ICD code used to specify a diagnosis of other congenital malformations of musculoskeletal system. 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 Q798 is used to code Poland syndrome

Poland syndrome (also Poland's syndrome, Poland's syndactyly, Poland sequence, and Poland's anomaly) is a rare birth defect characterized by underdevelopment or absence of the chest muscle (pectoralis) on one side of the body, and usually also webbing of the fingers (cutaneous syndactyly) of the hand on the same side (the ipsilateral hand). In most affected individuals, the missing part is the large section of the muscle that normally attaches to the upper arm on one side and the breastbone (sternum) on the other. Other abnormalities may occur on the affected side of the torso. In some cases, additional muscles in the chest wall, side, and shoulder are missing or underdeveloped.

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 Q79.8 and a single ICD9 code, 756.9 is an approximate match for comparison and conversion purposes.
