E16.8 — Other specified disorders of pancreatic internal secretion
E16.8 is a billable, specific ICD-10-CM code for other specified disorders of pancreatic internal secretion. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Increased secretion from endocrine pancreas of growth hormone-releasing hormone
- Increased secretion from endocrine pancreas of pancreatic polypeptide
- Increased secretion from endocrine pancreas of somatostatin
- Increased secretion from endocrine pancreas of vasoactive-intestinal polypeptide
Other codes that can never be billed with E16.8
These codes carry an Excludes1 note pointing at E16.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E16.8 alone.
- E22.0Acromegaly and pituitary gigantism
Risk adjustment
E16.8 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Medicare coverage
E16.8 is named in 4 Medicare coverage policies — 4 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How E16.8 is indexed
