ICD-9 header code V53.3

[dewittpe]

V53.3 is a header code used in CVD:

pccc/src/pccc.cpp

Lines 22 to 26 in 2a8b78e

	dx_cvd = {"4161","4168","4169","4240","4258","4242","4243","4250","4251","4252","4253",
	"4254","426","4270","4271","4272","4273","4274","4276","4277","4278","4279","4280","42883",
	"4291","4293","43311","7450","7451","7452","7453","7456","746","7471","7472","7473","7474",
	"74781","74789","9960","9961","99661","99662","V421","V422","V432","V433","V450","V4581",
	"V533"};

V53.31, V53.32, and V53.39 are the assignable codes under the V53.3 header:

These assignable codes are explicitly listed in the tech dep:

pccc/src/pccc.cpp

Lines 68 to 71 in 2a8b78e

	dx_tech_dep = {"5190","5364","9960","9961","9962","9964","99661","99662","99663","99666","99667",
	"99668","9969","V433","V440","V441","V442","V443","V444","V445","V446","V450","V451",
	"V452","V460","V461","V462","V5301","V5302","V5331","V5332","V5339","V5350","V5351",
	"V5359","V536","V550","V551","V552","V553","V554","V555","V556"};

As such, for consistency, it would be good to have the header V53.3 also map to tech dep, or to only have the explicit assignable codes. I suggest using the header code to be consistent with the use of other header codes in the software.

It is worth noting that V53.3 was a valid ICD-9 from the CDC through 2012 for "Cardiac device"
