Pelvic Inflammatory Disease

Pelvic inflammatory disease (PID) is an infection of the uterus, ovaries, and other female reproductive organs. PID causes scarring in these organs. This can lead to infertility, ectopic pregnancy, pelvic pain, abscesses (a collection of pus), and other serious problems.

Questions About A18.17Overview

Is A18.17 (Tuberculosis of genitourinary system) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report tuberculous female pelvic inflammatory disease on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does A18.17 group to?

When tuberculous female pelvic inflammatory disease is the principal diagnosis on an inpatient stay, it groups to MS-DRG 742, 743, 757, 758, 759, 974, 975, 976, with relative weights from 0.6636 to 2.8860 depending on complications. Higher weights mean higher Medicare reimbursement.

What is the ICD-9 equivalent of A18.17?

Under the General Equivalence Mappings, tuberculous female pelvic inflammatory disease converts to ICD-9-CM 016.60 (TB ovary & tube-unspec) and 016.70 (TB female gen NEC-unspec). 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.
