Other problems with newborn (P84)
ICD-10 code P84 is specifically used to classify a wide range of other problems with newborns related to oxygen deprivation, acid-base imbalances, and breathing difficulties occurring around birth.
This code covers conditions like neonatal acidemia, birth asphyxia, hypoxia, and various forms of metabolic and respiratory acidosis or alkalosis in newborns. Synonyms such as neonatal acidosis, moderate birth asphyxia, or anoxic encephalopathy help clarify the diagnoses captured under P84. It also includes issues like ineffective ventilation, blood oxygen levels below normal, and delayed brain injury due to oxygen deprivation (often called anoxic or hypoxic-ischemic encephalopathy). Additionally, it addresses symptoms such as uneven chest movement, neonatal respiratory disorders, and metabolic disorders affecting oxygen delivery and carbon dioxide elimination. Medical coders use this code to document these diverse neonatal complications that result from insufficient oxygen around the time of birth or disturbances in normal respiratory and metabolic balance, essential for accurate infant health records and care planning.
Instructional Notations
Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Acidemia of newborn
- Acidosis of newborn
- Anoxia of newborn NOS
- Asphyxia of newborn NOS
- Hypercapnia of newborn
- Hypoxemia of newborn
- Hypoxia of newborn NOS
- Mixed metabolic and respiratory acidosis of newborn
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- intracranial hemorrhage due to anoxia or hypoxia P52
- hypoxic ischemic encephalopathy [HIE] P91.6
- late metabolic acidosis of newborn P74.0
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Acidosis
A pathologic condition of acid accumulation or depletion of base in the body. The two main types are RESPIRATORY ACIDOSIS and metabolic acidosis, due to metabolic acid build up.
Acidosis, Lactic
Acidosis caused by accumulation of lactic acid more rapidly than it can be metabolized. It may occur spontaneously or in association with diseases such as DIABETES MELLITUS; LEUKEMIA; or LIVER FAILURE.
Acidosis, Renal Tubular
A group of genetic disorders of the KIDNEY TUBULES characterized by the accumulation of metabolically produced acids with elevated plasma chloride, hyperchloremic metabolic ACIDOSIS. Defective renal acidification of URINE (proximal tubules) or low renal acid excretion (distal tubules) can lead to complications such as HYPOKALEMIA, hypercalcinuria with NEPHROLITHIASIS and NEPHROCALCINOSIS, and RICKETS.
Acidosis, Respiratory
Respiratory retention of carbon dioxide. It may be chronic or acute.
Altitude
A vertical distance measured from a known level on the surface of a planet or other celestial body.
Altitude Sickness
Multiple symptoms associated with reduced oxygen at high ALTITUDE.
Aryl Hydrocarbon Receptor Nuclear Translocator
Aryl hydrocarbon receptor nuclear translocator is a basic HELIX-LOOP-HELIX MOTIF containing protein that forms a complex with DIOXIN RECEPTOR. The complex binds xenobiotic regulatory elements and activates transcription of a variety of genes including UDP GLUCURONOSYLTRANSFERASE. AhR nuclear translocator is also a subunit of HYPOXIA-INDUCIBLE FACTOR 1.
Cell Hypoxia
A condition of decreased oxygen content at the cellular level.
Diabetic Ketoacidosis
A life-threatening complication of diabetes mellitus, primarily of TYPE 1 DIABETES MELLITUS with severe INSULIN deficiency and extreme HYPERGLYCEMIA. It is characterized by KETOSIS; DEHYDRATION; and depressed consciousness leading to COMA.
Fetal Blood
Blood of the fetus. Exchange of nutrients and waste between the fetal and maternal blood occurs via the PLACENTA. The cord blood is blood contained in the umbilical vessels (UMBILICAL CORD) at the time of delivery.
Fetal Hypoxia
Deficient oxygenation of FETAL BLOOD.
Hydrops Fetalis
Abnormal accumulation of serous fluid in two or more fetal compartments, such as SKIN; PLEURA; PERICARDIUM; PLACENTA; PERITONEUM; AMNIOTIC FLUID. General fetal EDEMA may be of non-immunologic origin, or of immunologic origin as in the case of ERYTHROBLASTOSIS FETALIS.
Hypoaldosteronism
A congenital or acquired condition of insufficient production of ALDOSTERONE by the ADRENAL CORTEX leading to diminished aldosterone-mediated synthesis of Na(+)-K(+)-EXCHANGING ATPASE in renal tubular cells. Clinical symptoms include HYPERKALEMIA, sodium-wasting, HYPOTENSION, and sometimes metabolic ACIDOSIS.
Hypoxia
Sub-optimal OXYGEN levels in the ambient air of living organisms.
Hypoxia, Brain
A reduction in brain oxygen supply due to ANOXEMIA (a reduced amount of oxygen being carried in the blood by HEMOGLOBIN), or to a restriction of the blood supply to the brain, or both. Severe hypoxia is referred to as anoxia and is a relatively common cause of injury to the central nervous system. Prolonged brain anoxia may lead to BRAIN DEATH or a PERSISTENT VEGETATIVE STATE. Histologically, this condition is characterized by neuronal loss which is most prominent in the HIPPOCAMPUS; GLOBUS PALLIDUS; CEREBELLUM; and inferior olives.
Hypoxia-Inducible Factor 1
A basic helix-loop-helix transcription factor that plays a role in APOPTOSIS. It is composed of two subunits: ARYL HYDROCARBON RECEPTOR NUCLEAR TRANSLOCATOR and HYPOXIA-INDUCIBLE FACTOR 1, ALPHA SUBUNIT.
Hypoxia-Inducible Factor 1, alpha Subunit
Hypoxia-inducible factor 1, alpha subunit is a basic helix-loop-helix transcription factor that is regulated by OXYGEN availability and is targeted for degradation by VHL TUMOR SUPPRESSOR PROTEIN.
Hypoxia-Inducible Factor-Proline Dioxygenases
Dioxygenase enzymes that specifically hydroxylate a PROLINE residue on the HYPOXIA-INDUCIBLE FACTOR 1, ALPHA SUBUNIT. They are OXYGEN-dependent enzymes that play an important role in mediating cellular adaptive responses to HYPOXIA.
Hypoxia-Ischemia, Brain
A disorder characterized by a reduction of oxygen in the blood combined with reduced blood flow (ISCHEMIA) to the brain from a localized obstruction of a cerebral artery or from systemic hypoperfusion. Prolonged hypoxia-ischemia is associated with ISCHEMIC ATTACK, TRANSIENT; BRAIN INFARCTION; BRAIN EDEMA; COMA; and other conditions.
Oxygen
An element with atomic symbol O, atomic number 8, and atomic weight [15.99903; 15.99977]. It is the most abundant element on earth and essential for respiration.
Tumor Hypoxia
Hypoxic conditions in tumor cells due to the tumor outgrowing its blood supply. It is associated with increased METASTASIS and resistance to RADIOTHERAPY and DRUG THERAPY.
