Clinical InformationClinical

  • Congenital Hyperinsulinism

    a familial, nontransient hypoglycemia with defects in negative feedback of glucose-regulated insulin release. clinical phenotypes include hypoglycemia; hyperinsulinemia; seizures; coma; and often large birth weight. several sub-types exist with the most common, type 1, associated with mutations on an atp-binding cassette transporters (subfamily c, member 8).

  • Fanconi Syndrome

    a hereditary or acquired form of generalized dysfunction of the proximal kidney tubule without primary involvement of the kidney glomerulus. it is usually characterized by the tubular wasting of nutrients and salts (glucose; amino acids; phosphates; and bicarbonates) resulting in hypokalemia; acidosis; hypercalciuria; and proteinuria.

  • Neonatal Hypoglycemia

    blood glucose concentration below the lower limit of established reference ranges in a newborn.

  • Idiopathic Ketotic Hypoglycemia|Accelerated Starvation

    ketotic hypoglycemia that usually occurs in young, thin children in association with infection or fasting, and which typically resolves by age 6-8 years.

  • Ketotic Hypoglycemia

    a condition in which hypoglycemia is accompanied by ketosis. this condition may be a manifestation of another condition such as glycogen storage disease, ketone utilization defects, growth hormone deficiency, or cortisol deficiency.

Patient EducationClinical

Hypoglycemia

Blood glucose, or blood sugar, is the main sugar found in your blood. It is your body's primary source of energy. It comes from the food you eat. Your body breaks down most of that food into glucose and releases it into your bloodstream. When your blood glucose goes up, it signals your pancreas to release insulin.

Questions About P70.4Overview

Is P70.4 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other neonatal hypoglycemia on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What is the ICD-9 equivalent of P70.4?

Under the General Equivalence Mappings, other neonatal hypoglycemia converts to ICD-9-CM 775.6 (neonatal hypoglycemia). The mapping is approximate, so confirm the match fits the documentation.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
