Z32.01 ICD-10-CM Code: Encounter for pregnancy test, result positive

Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.

Inpatient Payment Groups (MS-DRG)

Potential MS-DRG participation — not a DRG assignment.

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v44, Appendix B.

  • MS-DRG 951 — OTHER FACTORS INFLUENCING HEALTH STATUS (MDC 23)

A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.

Coder workflow for Z32.01

MedCoder structured workflow — derived from this code’s own official record

Before you code Z32.01

  1. Confirm the reason for the encounter this Z code records: the circumstance it records. Check whether the code may be reported as first-listed or principal — some Z codes are limited to one position — and do not report a history or status code for a condition documented as current. Z code categories and their reporting positions (Guidelines I.C.21.c, I.C.21.c.15).

    Guide: Z codes as principal or first-listed diagnosis →

Documentation check

The provider’s diagnostic statement
Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).
The reason for the encounter
Whether the code records the encounter’s purpose, a status, or a history — and whether it may be first-listed (Guidelines I.C.21.c).

Every row is derived from this code’s own record — its title, tabular notes, 7th-character family and same-category siblings — with fixed MedCoder wording; nothing is inferred about a patient. The official notes and guideline text are in the sections each row links to, and they control.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name Z32.01 or its code family, from the CMS ICD-10-CM tabular instructional notes. Tabular-note edges are stored at the code family level that carries each note.

Referenced by 1 Excludes1 note: Z34 — Encounter for supervision of normal pregnancy (via Z32.0.-).

These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.

Referenced by 13 Excludes2 notes: Z00 — Encounter for general examination without complaint, suspected or reported diagnosis (via Z32.-), Z00-Z13 — Persons encountering health services for examinations (Z00-Z13) (via Z32.-), Z01 — Encounter for other special examination without complaint, suspected or reported diagnosis (via Z32.-), Z01.4 — Encounter for gynecological examination (via Z32.0.-), Z02 — Encounter for administrative examination (via Z32.-), Z03 — Encounter for medical observation for suspected diseases and conditions ruled out (via Z32.-), Z04 — Encounter for examination and observation for other reasons (via Z32.-), Z05 — Encounter for observation and evaluation of newborn for suspected diseases and conditions ruled out (via Z32.-), Z08 — Encounter for follow-up examination after completed treatment for malignant neoplasm (via Z32.-), Z09 — Encounter for follow-up examination after completed treatment for conditions other than malignant neoplasm (via Z32.-), Z11 — Encounter for screening for infectious and parasitic diseases (via Z32.-), Z12 — Encounter for screening for malignant neoplasms (via Z32.-), Z13 — Encounter for screening for other diseases and disorders (via Z32.-).

These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.

MS-DRG Grouper Relationships (FY2027)

Potential MS-DRG participation — not a DRG assignment.

FY2027 MS-DRG: not on the CMS CC/MCC list — as a secondary diagnosis this code does not change MS-DRG severity for that release.

Named in the grouper logic of 1 MS-DRG: DRG 951 (MDC 23).

From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
