Happy Kid Vital Height vs Length LOINC

[Joe Herdliska]

Test patient Happy Kid has a vital of Height (LOINC 8302-2).  This is part of the LOINC group LG34373-7 Body Height.  This LOINC group also incudes 8306-3 for Body Height -- Lying. Per CDC guidelines for growth charts, length is acceptable to use up to 36 months.  Since Happy Kid is under 36 months, our CCDA codes the height as Body Height -- Lying (8306-3).  We are getting a failure because the validator is specifically looking for 8302-2.  Has it been considered to include all LOINCs in LG3473-7 for the height/length vital based on age? Is coding the height/length as 8306-3 for Happy Kid acceptable?  Thank you for any input/guidance you may be able to provide.

I wonder if including both codes might be the best. Since the input is the Height (which implies standing height, though with age context could be seen as lying height), it's going to expect that in the input. What you could do is when you have an incoming C-CDA that specifies standing height for a patient under 36 months, you could retain that code (since that's what it came in as) and add a second one for the lying height. I don't have the clinical knowledge to say how this data would be reconciled though, so I don't know if those values are always a 1-to-1 match.

The validator is only checking for 8302-2 , so you will get an error unless you use that value. The tool as currently designed does not check for multiple codes.

Since they are both part of LG34373-7, would it be valid to use the  Body Height -- Lying (8306-3) for Happy Kid (24 months & 3 weeks at time of visit)? Is that a notable exception for testing Happy Kid, should the validator be updated, or is this invalid? We feel that it is valid to code it with 8306-3 but looking for input based on ETT validation failure. I appreciate your view on this matter. Thank you.

I just wanted to follow up to get your thoughts on if it would be valid to use the  Body Height -- Lying (8306-3) for Happy Kid (24 months & 3 weeks at time of visit)?
