About coding salpingitis chlamydia
The ICD-10-CM code for salpingitis chlamydia is A56.11 (Chlamydial female pelvic inflammatory disease).
Within A56.1 (chlamydial infection of pelviperitoneum and other genitourinary organs), A56.11 is specifically for chlamydial female pelvic inflammatory disease. Related codes cover other chlamydial genitourinary infection (A56.19).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 689 (Kidney and Urinary Tract Infections with MCC, relative weight 1.1415) and DRG 690 (Kidney and Urinary Tract Infections without MCC, relative weight 0.801), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
