Perinatal infections
Default principal diagnosis: inpatient Yes · outpatient Yes

Clinical InformationClinical

  • 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.

  • 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.

  • 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.

  • Foreign Body in Penis

    extraneous material located within the penis.

Patient EducationClinical

Skin Infections

Your skin is your body's largest organ. It has many different functions, including covering and protecting your body. It helps keep germs out. But sometimes the germs can cause a skin infection. It often happens when the germs enter your body through a break, cut, or wound on your skin.

Questions About P39.4Overview

Is P39.4 (Other infections specific to the perinatal period) a billable code?

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

What is the ICD-9 equivalent of P39.4?

Under the General Equivalence Mappings, neonatal skin infection converts to ICD-9-CM 771.89 (perinatal infection NEC). 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.
