ICD-10-CM Code Q25.5
Atresia of pulmonary artery

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

Q25.5 is a billable ICD code used to specify a diagnosis of atresia of pulmonary artery. 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 Q255 is used to code Pulmonary atresia

Pulmonary atresia is a congenital malformation of the pulmonary valve in which the valve orifice fails to develop. The valve is completely closed thereby obstructing the outflow of blood from the heart to the lungs. The pulmonary valve is located on the right side of the heart between the right ventricle and pulmonary artery. In a normal functioning heart, the opening to the pulmonary valve has three flaps that open and close like one way doors. As these flaps open and close they allow blood to flow forward into the pulmonary artery and on to the lungs where the blood becomes oxygenated, and prevent backward flow into the right ventricle. With the disease pulmonary atresia, the flap-like openings are completely covered by a layer of tissue, thus preventing the ability of blood flow to the lungs to become oxygenated. The body requires oxygenated blood for survival. Pulmonary atresia is not threatening to a developing fetus however, because the mother's placenta provides the needed oxygen since the baby's lungs are not yet functional. Once the baby is born its lungs must now provide the oxygen needed for survival, but with pulmonary atresia there is no opening on the pulmonary valve for blood to get to the lungs and become oxygenated and the only source of pulmonary blood flow is a patent ductus arteriosus. Due to this, the newborn baby is blue in color and pulmonary atresia can usually be diagnosed within hours or minutes after birth.

Pulmonary artery coarctation and atresia (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 Q25.5 and a single ICD9 code, 747.31 is an approximate match for comparison and conversion purposes.
