ICD-10 Code O99.73: Diseases of the skin and subcutaneous tissue complicating the puerperium
What is this code?
ICD-10 codes are diagnosis classification codes used in healthcare records, reporting, coding workflows, and billing support. This code sits within the broader ICD-10 area for Pregnancy, childbirth and the puerperium (O00-O9A).
đź“‹Clinical overview
This ICD-10 code is commonly used when documentation describes a maternal skin or subcutaneous-tissue disease complicating pregnancy, childbirth, or the puerperium. The most accurate code depends on maternal timing and whether the chart more specifically identifies the underlying dermatologic diagnosis elsewhere in the record.
When is it used?
- May be used when a clinician documents diseases of the skin and subcutaneous tissue complicating the puerperium in a patient's medical record.
- May appear in hospital records, claims, referrals, and clinical documentation.
- This code can be used as a clinically usable diagnosis entry in standardized coding workflows.
What it does not mean
- A code alone does not explain severity, treatment plan, or outcome.
- A medical code should not be treated as a substitute for a doctor's diagnosis or advice.
đź©şClinical context
- Obstetric, dermatology, maternal-fetal medicine, inpatient, delivery, postpartum, and prenatal documentation where maternal skin or subcutaneous-tissue disease materially affects pregnancy monitoring or management.
- Coding and utilization-review workflows where the record clearly ties maternal skin or subcutaneous-tissue disease to pregnancy, childbirth, or the puerperium and maternal timing changes the final complication code.
- Related procedures or service context already linked on this page include Obstetric ultrasound, Fetal nonstress testing.
- Maternal skin or subcutaneous-tissue disease follow-up often includes symptom review, medication or treatment review, obstetric monitoring, and coordination with dermatology or maternal-fetal medicine.
- Documentation usually becomes more specific when the chart identifies trimester or delivery timing, the underlying dermatologic diagnosis, severity, and whether additional maternal-fetal surveillance is needed.
- Specialist context already linked on this page includes Obstetrician, Gynecologist, Dermatologist.
🔍Key distinctions
- This ICD-10 family captures maternal skin or subcutaneous-tissue disease as a pregnancy-related, childbirth-related, or puerperium-related complication, while separate diagnosis coding may still carry the underlying dermatologic disorder detail documented elsewhere in the chart.
- Trimester or maternal timing detail matters, and clearer chart language about the underlying skin or subcutaneous-tissue condition can add specificity beyond this broad maternal complication family.
- Puerperium or postpartum maternal skin or subcutaneous-tissue documentation is coded separately from pregnancy or childbirth encounters because the maternal recovery context has changed.
