The above claim has been largely debunked, and even Snopes has determined that claim to be mostly false-

What's True:
The bill could greatly expand the obligation on healthcare providers to file fetal death certificates. In order to fully discharge that legal obligation, healthcare providers would, in many cases, have to consult with patients about the details of the fetal death, even if the patients would strongly prefer not to discuss fetal death certificates and similar considerations. Thus, the bill was likely to multiply the trauma suffered by patients who undergo an abortion or miscarriage in Pennsylvania.

What's False:
However, Pennsylvania law does not require patients themselves to register fetal deaths, or file, obtain or pay for a fetal death certificate, and it does not fine them for having a miscarriage. The bill would not introduce such legal requirements.

This is another classic example of why I don't trust either political extreme, and the left have their share of conspiracy theories just like the right does. Lastly, I am personally opposed to House Bill 118 of 2021, as Pennsylvania already has enough restrictions on abortions in place and said restrictions have done little to curb abortion procedures, so more of the same would be pointless.

does this also need to be done for abortions, as miscarry is a natural spontaneous abortion

If you're going to go down this sort of road, you shouldn't make it so easy to refute, unless you get participation points from comments---I'm still trying to figure out how that one works.

So I'm struggling a little with this person's characterization for two reasons:

One, the medical professional is the one who fills out the death certificate, so I'm not clear where the whole "force [the woman] to fill out this form" comes from.

Two, having read HB118, I did not see anything to suggest that the legislature voted to "fine women who miscarry." The only costs I even see mentioned are if the woman chooses to have the remains disposed of in a manner that goes beyond "usual and customary."

So what am I missing here?
