Diagnosis coding corner: Perinatal conditions can be coded for life

Why This Topic Matters

Perinatal diagnoses can affect documentation and coding well beyond the birth hospitalization, so accurate understanding of the relevant chapter guidance helps maintain consistent records across the patient’s lifetime.

Article Sections

1. ICD-9-CM perinatal coding guidance

2. Examples and supporting Chapter 15 guidance

   Reviews broad examples of perinatal condition categories and discusses how Chapter 15 guidance relates to other ICD-9-CM chapters. It also notes how unspecified or corrected-history concepts may be handled at a high level.

3. Perinatal conditions in ICD-10

   Summarizes the parallel ICD-10-CM framework for perinatal conditions and notes the relationship to official ICD-10 coding guidelines. This section focuses on the chapter-level structure rather than case-specific selection details.
