About coding lymphangitis puerperal
The ICD-10-CM code for lymphangitis puerperal is O86.89 (Other specified puerperal infections). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on O86.89.
Within O86.8, choose O86.89 (Other specified puerperal infections) only when documentation doesn't support a more specific option: puerperal septic thrombophlebitis (O86.81).
Use an additional code (B95-B97), to identify infectious agent.
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
