ICD-10-CM Codes›H00–H59›H30-H36›H35
- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Chronic Condition
H35.729 is a billable ICD-10-CM diagnosis code for serous detachment of retinal pigment epithelium, unspecified eye. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 124 through 125. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 74 closely related codes. The code is flagged as an unspecified code, since codes identifying laterality exist in the same family. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Retinal and vitreous conditions.
