I am going through the 2015 Coding Handbook for CM and PCS. One of the questions to code was "Noncompliance with medication, unintentional, due to patient's advanced age." I chose "Z91.14 - Patient's other noncompliance with medication regimen." However, the correct answer was "Z91.130 - Underdosing of medication regimen due to age-related debility." The question is, is the default for noncomplaince "underdosing" if not specified to obtain the surrounding specificity. Just trying to understand when it is safe to assume underdosing.
