Primary ICD-10-CM Codes for postpartum hypertension
Decision Criteria
clinical Criteria
- Presence of pre-existing hypertension and new-onset proteinuria
documentation Criteria
- Explicit mention of pre-eclampsia complicating the puerperium
Applicable To
- Pre-eclampsia superimposed on chronic hypertension in the puerperium
Clinical Validation Requirements
- Pre-existing hypertension diagnosis before pregnancy
- New-onset proteinuria (≥300 mg/24h) or end-organ damage
- BP ≥140/90 mmHg after delivery
Code-Specific Risks
- Misclassification if pre-eclampsia is not documented
- Incorrect sequencing with chronic hypertension codes
Coding Notes
- Ensure documentation specifies pre-existing hypertension and presence of pre-eclampsia.
O16.5 - Unspecified maternal hypertension complicating the puerperium
Use when hypertension is first noted postpartum and is not specified as pre-existing or gestational.
Applicable To
- Unspecified hypertension in the postpartum period
Excludes
- Pre-existing hypertension with pre-eclampsia (O11.5)
- Gestational hypertension (O13.5)
Clinical Validation Requirements
- No documentation of pre-existing or gestational hypertension
- BP elevation first documented ≥48 hours postpartum
Coding Notes
Ensure documentation clearly states the lack of prior hypertension history.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Postpartum Hypertension to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code O11.5.
Impact
Clinical: May lead to inappropriate treatment plans., Regulatory: Non-compliance with documentation standards., Financial: Potential for claim denials or reduced reimbursement.
Mitigation Strategy
Thorough patient history review, Clear documentation of hypertension onset
Impact
Reimbursement: Incorrect coding may lead to denied claims or incorrect DRG assignment., Compliance: Non-compliance with coding guidelines can result in audits., Data Quality: Inaccurate data affects clinical outcomes and research.
Mitigation Strategy
Verify and document if hypertension was present before pregnancy to use O11.5.
Impact
Incorrect classification of hypertension type can lead to audit findings.
Mitigation Strategy
Ensure thorough documentation and correct code selection.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
