Wiki Need clarification w/ 5th digits 640-649

Best answers
Hello all. I am a new coder. I am having trouble w/ the 5th digits for the 640-649 series.

I have a pt 5d post-partum w/ HTN. Pre-eclampsia complicating the pregnancy.

I coded 642.41--pregnancy delivered with mention of antepartum complication during current episode of care. It was recommended to use 642.44 post-partum condition or complication.

Can anyone explain the 5th digits here? 5th digit 4 reads to me like it is just a post-partum complication only.

Thanks--I appreciate any and all feedback. SB
5th digits Chapter 11

If the patient is still in the hospital from the delivery (current episode of care) the fifth digit code would be 2 (642.42). If this is a foll0w-up or the patient was re-admited or in observation for the problem (a new episode of care) the fifth digit would be 4 (642.44). There is a good description of the uses for the fifth digits on page 199 of the 2012 ICD-9.
I hope this helps.
