Patient admitted for oversewing of Patent Foramen Ovale (PFO).

The ACHI Index does not appear to provide a pathway leading directly to a code to classify the procedure of oversewing of PFO.

Our interpretation of research is PFO is a type of atrial septal defect.

ICD-10-AM appears to classify PFO as an ASD.

Q21.1 Atrial septal defect
Excludes: primum atrial septal defect (Q21.21)
Q21.10 Atrial septal defect, unspecified
Q21.11 Patent or persistent foramen ovale
Nonclosure of foramen ovale
Q21.12 Sinus venosus defect
Q21.13 Ostium secundum defect
Type II atrial septal defect
Q21.14 Coronary sinus septal defect
Atrial septal defect located in coronary sinus
Q21.15 Lutembacher's syndrome
Q21.19 Other specified atrial septal defect
Cor triloculare biventriculare
Single common atrium

Possible Index pathways that have been considered to classify the procedure of oversewing of PFO are:

Closure / atrial / septal defect (open) (with patch graft) 38742-02 [617]
Or
Procedure / atrium, heart (intrathoracic) NEC 96221-01 [606]

1. Please advise if Patent Foramen Ovale (PFO) is an atrial septal defect?
2. Please advise the correct ACHI Index pathway to follow and code to assign to classify the procedure of oversewing of PFO.

VICC research indicates that the enquirer correctly interprets a patent foramen ovale (PFO) to be a type of atrial septal defect (ASD). It also indicates that PFOs can be closed by a number of methods, including oversewing.

Therefore VICC advises when oversewing of PFO is documented to follow the lead term Closure and the Index pathway Closure/atrial/septal defect (open)(with patch graft) to assign 38742-02 [617] Closure of atrial septal defect.
