Extremely low birth weight newborn, 500-749 grams

This code identifies a liveborn infant with an extremely low birth weight, specifically weighing between 500 and 749 grams at the time of birth. This weight range signifies significant prematurity and often correlates with substantial health risks and developmental challenges.

Assign this code for newborns documented with a birth weight within the 500-749 gram range. This is typically used in conjunction with codes for prematurity and other conditions related to low birth weight. Documentation must explicitly state the birth weight in grams.

• Always sequence this code after the appropriate Z38 code for liveborn infant.
• Do not confuse with codes for other low birth weight ranges; ensure the documented weight falls precisely within 500-749 grams.
• Verify the birth weight is recorded in grams, not pounds and ounces, to avoid miscoding.
