Is I87.309 billable?

Yes, but I87.309 is an unspecified code. I87.309 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, I87.309 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting I87.309 — the more specific alternatives are listed below.

Inclusion terms

Alternative wording in documentation that is classified to I87.309.

  • Chronic venous hypertension NOS

Excludes1 — never code together — inherited from I87.3

The conditions below can never be reported together with I87.309 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • chronic venous hypertension due to deep vein thrombosis (I87.0-)
  • varicose veins of lower extremities (I83.-)

Excludes2 — not included here — inherited from Chapter 9

The conditions below are not part of I87.309, but a patient may have both at the same time. When documentation supports it, I87.309 and the excluded code may both be reported.

  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
  • systemic connective tissue disorders (M30-M36)
  • transient cerebral ischemic attacks and related syndromes (G45.-)
