  • F69 is an unspecified code: use it only when the record doesn't document anything more specific. If the record has more detail, check the other codes under F60-F69 below.
  • As a secondary diagnosis it is not a CC or MCC, so it doesn't raise the MS-DRG payment.
  • Doesn't count toward a Medicare Advantage risk score (no HCC in V28).
  • AHRQ's Chronic Condition Indicator classes it as chronic: expected to last 12 months or longer and to limit daily life or need ongoing care.
  • Expected only for adult patients. (Adult list)
