ICD-10 Code O99.7: Diseases of the skin and subcutaneous tissue complicating pregnancy, childbirth and the puerperium

O99.7 is an ICD-10 diagnosis entry used to group records related to Diseases of the skin and subcutaneous tissue complicating pregnancy, childbirth and the puerperium. You may see this entry in coding references, medical records, or claims workflows when a broader diagnosis category is being reviewed before a more specific code is chosen. ICD-10 entries help standardize how diagnoses are organized for coding, reporting, analytics, and documentation. This code sits within the broader ICD-10 area for Pregnancy, childbirth and the puerperium (O00-O9A).

What is this code?

ICD-10 entries help standardize how diagnoses are organized for coding, reporting, analytics, and documentation. This code sits within the broader ICD-10 area for Pregnancy, childbirth and the puerperium (O00-O9A).

đź“‹Clinical overview

This ICD-10 overview page groups maternal skin-and-subcutaneous-tissue complication codes under a broad parent code. The most accurate billable code usually depends on whether the record specifies pregnancy versus childbirth versus puerperium timing and whether the underlying dermatologic diagnosis is named more specifically.

When is it used?

  • May be used when a clinician documents diseases of the skin and subcutaneous tissue complicating pregnancy, childbirth and the puerperium in a patient's medical record.
  • May appear in hospital records, claims, referrals, and clinical documentation.
  • This code may act more like a grouping or parent code, so a more specific child code may be used in final documentation when available.

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.
  • This entry may represent a broader category rather than the most specific billable code.

đź©şClinical context

When commonly used
  • Parent-code browsing, coding review, and clinical-reference workflows where the goal is to understand the broader maternal dermatologic complication family before selecting a timing-specific child code.
  • Documentation review where the chart clearly links skin or subcutaneous-tissue disease to obstetric care, but the user is navigating the broad umbrella page rather than a more specific child page.
Common workup
  • Related procedures or service context already linked on this page include Obstetric ultrasound, Fetal nonstress testing.
Common management context
  • Overview-level review often includes symptom review, medication or treatment review, obstetric monitoring, and coordination with dermatology or maternal-fetal medicine.
  • The final billable code usually becomes more specific when the chart identifies maternal timing and the underlying dermatologic diagnosis elsewhere in the record.
  • Specialist context already linked on this page includes Obstetrician, Gynecologist, Dermatologist.

🔍Key distinctions

Important notes
  • This parent page is an umbrella overview for multiple maternal skin-and-subcutaneous-tissue complication codes rather than the most specific billable child code.
  • Maternal timing and the underlying dermatologic diagnosis are the key distinctions across this family.
  • This overview page groups maternal skin-and-subcutaneous-tissue-disease codes across pregnancy, childbirth, and the puerperium, so the final billable code usually depends on maternal timing and whether the chart identifies a more specific dermatologic condition.
Important exclusions
  • herpes gestationis (O26.4)
  • pruritic urticarial papules and plaques of pregnancy (PUPPP) (O26.86)
