Clinical InformationClinical
Erdheim-Chester Disease|ECD|Lipogranulomatosis|Polyostotic Sclerosing Histiocytosis
a very rare, multisystem non-langerhans cell histiocytosis that predominantly affects adults. it is characterized by the proliferation in the tissues of lipid-laden macrophages and the presence of multinucleated giant cells. it results in sclerosis of the long bones and failure of the affected organs. patients may present with bone pain, exophthalmos, ataxia, liver failure, kidney failure, and hypopituitarism.Farber Lipogranulomatosis
a very rare autosomal recessive metabolic disorder affecting lipid metabolism. it is caused by mutations in the asah1 gene and is characterized by fatty accumulation in the body tissues. patients develop lipogranulomas in the skin and internal organs, edema and pain in the joints and a hoarse voice. it may be associated with intellectual disability.Large Lipogranuloma Assessment|LPGNLMLG|Large Lipogranuloma|Large Lipogranuloma
an evaluation of the presence or degree of large lipogranuloma in a sample.Lipogranuloma
an inflammatory lesion comprised of lipoid material.Pseudoporphyria
a drug-induced photodermatosis characterized by skin fragility, erythema, and the appearance of tense bullae, erosions and scarring in the absence of abnormalities in porphyrin metabolism.

Questions About T88.8XXSOverview
Is T88.8XXS a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other specified complications of surgical and medical care, not elsewhere classified, sequela on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What does the 7th character S in T88.8XXS mean?
The final character S makes this a sequela code: it reports a lingering problem that remains after the other specified complications of surgical and medical care, not elsewhere classified itself has resolved, not the original event.
What MS-DRG does T88.8XXS group to?
When other specified complications of surgical and medical care, not elsewhere classified, sequela is the principal diagnosis on an inpatient stay, it groups to MS-DRG 922, 923, with relative weights from 1.0177 to 1.7494 depending on complications. Higher weights mean higher Medicare reimbursement.
Is T88.8XXS exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for other specified complications of surgical and medical care, not elsewhere classified, sequela on inpatient claims.
What is the ICD-9 equivalent of T88.8XXS?
Under the General Equivalence Mappings, other specified complications of surgical and medical care, not elsewhere classified, sequela converts to ICD-9-CM 909.3 (late eff surg/med compl). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
