E55.0Rickets, active

E55.0 is the ICD-10-CM diagnosis code for rickets, active. It belongs to category E55 (vitamin D deficiency), block E50-E64 (other nutritional deficiencies) and chapter 4 (endocrine, nutritional and metabolic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within E55 (vitamin D deficiency), E55.0 is specifically for rickets, active. Related codes cover unspecified (E55.9).

Don't report E55.0 together with the conditions in its Excludes1 note: celiac rickets (K90.0), Crohn's rickets (K50.-), hereditary vitamin D-dependent rickets (E83.32), inactive rickets (E64.3) and 3 more.

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 553 (Bone Diseases and Arthropathies with MCC, relative weight 1.2494) and DRG 554 (Bone Diseases and Arthropathies without MCC, relative weight 0.8331), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 268.0 (rickets, active).
