Pre-existing hyp chronic kidney disease comp the puerperium

This code signifies a patient with pre-existing chronic kidney disease (CKD) that is complicated by pre-existing hypertension, and this combined condition is adversely affecting the patient during the puerperium (the period immediately following childbirth). It indicates that the pre-existing hypertensive CKD is a factor in the patient's post-delivery care and recovery.

Use this code when documentation clearly states that a patient with a history of both hypertension and chronic kidney disease is experiencing complications related to these conditions during the postpartum period. Supporting documentation would include physician notes detailing the pre-existing nature of both conditions and their impact on the puerperal state.

• Always sequence this code as a primary diagnosis when it is the main reason for the encounter during the puerperium.
• Ensure documentation specifies both "pre-existing hypertension" and "pre-existing chronic kidney disease" to justify this specific code.
• Do not use this code for gestational hypertension or new-onset CKD during pregnancy or the puerperium; those have different code assignments.
