Other infections specific to the perinatal period (P39)

The ICD-10 code section P39 covers other infections specific to the perinatal period, detailing infections that occur in newborns around the time of birth. These codes are used to classify a range of infectious conditions affecting neonates, helping healthcare professionals document and treat these specialized early-life infections.

This section includes specific codes such as P39.0 for neonatal infective mastitis, which is also known as neonatal staphylococcal mastitis or neonatal breast infection. P39.1 covers neonatal conjunctivitis and dacryocystitis, common terms for eye infections in newborns like bacterial or chlamydial conjunctivitis. P39.3 is for neonatal urinary tract infections caused by bacteria such as Escherichia coli or Pseudomonas. P39.4 addresses neonatal skin infections including infected abrasions and superficial wounds, while P39.8 captures other specified infections like neonatal necrotizing fasciitis or perinatal staphylococcal infections. The category P39.9 is designated for unspecified infections occurring during the perinatal period. These codes assist in accurately identifying infections unique to the perinatal timeframe, ensuring appropriate clinical care and coding accuracy for early neonatal infections.

Instructional Notations

Use Additional Code

The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

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.

Chlamydia trachomatis

Type species of CHLAMYDIA causing a variety of ocular and urogenital diseases.

Conjunctivitis

INFLAMMATION of the CONJUNCTIVA.

Conjunctivitis, Acute Hemorrhagic

A highly contagious disease characterized by subconjunctival hemorrhage, sudden swelling of the eyelids and congestion, redness, and pain in the eye. Epidemic conjunctivitis caused by Enterovirus 70 (EV-70) was first described in Africa in 1969. It is caused also by Coxsackievirus A24 variant (CA24v). Epidemics by this organism have appeared most frequently in Asia.

Conjunctivitis, Allergic

Conjunctivitis due to hypersensitivity to various allergens.

Conjunctivitis, Bacterial

Purulent infections of the conjunctiva by several species of gram-negative, gram-positive, or acid-fast organisms. Some of the more commonly found genera causing conjunctival infections are Haemophilus, Streptococcus, Neisseria, and Chlamydia.

Conjunctivitis, Inclusion

An infection of the eyes characterized by the presence in conjunctival epithelial cells of inclusion bodies indistinguishable from those of trachoma. It is acquired by infants during birth and by adults from swimming pools. The etiological agent is CHLAMYDIA TRACHOMATIS whose natural habitat appears to be the genito-urinary tract. Inclusion conjunctivitis is a less severe disease than trachoma and usually clears up spontaneously.

Conjunctivitis, Viral

Inflammation, often mild, of the conjunctiva caused by a variety of viral agents. Conjunctival involvement may be part of a systemic infection.

Ecthyma

An ulcerative pyoderma usually caused by group A beta-hemolytic streptococcal infection at the site of minor trauma. (Dorland, 27th ed)

Ecthyma, Contagious

An infectious dermatitis of sheep and goats, affecting primarily the muzzle and lips. It is caused by a poxvirus and may be transmitted to man.

Mastectomy

Surgical procedure to remove one or both breasts.

Orf virus

The type species of PARAPOXVIRUS which causes a skin infection in natural hosts, usually young sheep. Humans may contract local skin lesions by contact. The virus apparently persists in soil.

Parapoxvirus

A genus of the family POXVIRIDAE, subfamily CHORDOPOXVIRINAE, which infect ungulates and may infect humans. ORF VIRUS is the type species.

Pyoderma

Any purulent skin disease (Dorland, 27th ed).

Pyoderma Gangrenosum

An idiopathic, rapidly evolving, and severely debilitating disease occurring most commonly in association with chronic ulcerative colitis. It is characterized by the presence of boggy, purplish ulcers with undermined borders, appearing mostly on the legs. The majority of cases are in people between 40 and 60 years old. Its etiology is unknown.

Seroma

Tumor-like sterile accumulation of serum in a tissue, organ, or cavity. It results from a tissue insult and is the product of tissue inflammation. It most commonly occurs following MASTECTOMY.

Trachoma

A chronic infection of the CONJUNCTIVA and CORNEA caused by CHLAMYDIA TRACHOMATIS.
